Introduction

In terms of training, what is the difference between a good bodybuilder and a great bodybuilder? It's not that the great bodybuilder works out longer, with more intensity or with heavier weights. The factor in training that separates the two is that the great bodybuilder has a complete routine. It's a routine that includes isolation work to keep their body in proportion.

Some weightlifters often make the mistake that isolation work is useless and a full compound routine is all one needs to build muscle. While compounds are the quickest way to work your body, they fail to fully exhaust the muscles. This is where isolation work is needed.

While a compound workout is faster, isolations will better target each individual muscle, resulting in a complete workout. This puts more stress on the muscles, and thus makes them grow better than a full compound workout.

Read on and learn why isolations are so important, and how a full isolation routine can actually be a benefit for some people. I will go through the benefits and the negatives of isolation work, and which isolations are best used to gain the most muscle mass.


Question
What Is The Best All Isolation Workout? Be Specific.

The best all isolation workout would be one that targets every muscle only once, in order to be efficient with your time. There is no benefit working the same muscle with more than one exercise per day. Plus for a workout to be the best that it can be, no muscle should be neglected.

The workout will be split into 3 parts over a 12-week period, in order to prevent any muscle adaptation. The first part is designed to be more strength oriented to prepare you for the second half. The second part is designed for size gains. The third part is intense, as it incorporates the benefits of strength and size gains. It is done last in the routine because your body will need days off to recover from the whole routine, especially the third part.

Each workout should not last for more than an hour, as isolation exercises are able to be performed faster and with less rest than compounds.

The whole routine would look like this:

    • Weeks 1-5 : Part 1 - Strength Gains
    • Weeks 6-10 : Part 2 - Size Gains
    • Weeks 6-12 : Part 3 - Intense Size and Strength Gains
    • Week 13 : Rest

Repeat

The best all isolation workout would look like this:

Exercise Reference Guide

While all of the following are isolation exercises, they do not only use a single muscle during the exercise. It is rare to find an exercise without more than one muscle being worked in it, whether it is a secondary muscle or a stabilizer assisting the main muscle. The main focus for isolation work is to concentrate fully on using the main muscle to move the weight.

Main Muscles Worked - The muscles that are used the most during the exercise.

Secondary Muscles Worked -Muscles that assist the main muscles in the exercise.

Stabilizers - Muscles that are not worked by movement, but rather assist in stabilizing the body in addition to the weight of the exercise.

      2. Wrist Extensors

What To Do:

      1. Set an incline bench at the lowest possible angle. Then, with a dumbbell in each hand, lie face down on the bench so that the top of the bench is supporting your chest.
      2. Extend your arms in front of you so that they are perpendicular to the angle of the bench. Your palms should be facing each other and your elbows should be slightly bent.
      3. Maintaining the slight bend in your elbows, lift the weights by pulling your arms apart in an arcing motion. Think about trying to squeeze your shoulder blades together.
      4. Continue moving your elbows up until the dumbbells are at either side of your head. Slowly return to the starting position.

Main Muscles Worked:

      1. Tibialis Anterior

Secondary Muscles Worked:

        None

Stabilizers:

        None

What To Do:

      1. 1. To do Smith-machine reverse calf raises, position the bar high enough on the rack so it can lie comfortably on the shoulders.
      2. 2. Use a platform to stand on; the same you'd use for normal raises, but instead of keeping your heels on the floor, this time the toes start on the floor with heels elevated onto the platform. Align the platform so it is inline with the bar. If you put it forward/back, it will emphasize higher or lower on the calf. Similarly, the stance you use can affect where it hits; the closer your feet are, the sides will hit isolated, whereas the farther apart feet are, the more front tibialis will hit.
      3. 3. From there you will push down with your heel, the opposite of pushing up with your arch for calf raises.

A lot of exercises and muscles were mentioned here. Most of them you've heard of before, but for the ones that may sound strange and you want to learn more about, a complete list of muscles written in this article can be found at this link.

Nutrition Section Of The Workout

As with any workout routine, the proper nutrition is required to feed your body the nutrients it needs to properly repair itself and build muscle after a workout. Creatine is a widely popular and recommended supplement to take, along with a post workout protein shake. Multivitamins are also strongly recommended to replenish your body with needed vitamins and minerals that you may not get enough or any at all during the day.

Fat:

Healthy fats are required in a bodybuilding diet because they aid in maintaining healthy hair and skin, promoting healthy cell function, function in energy storage and vitamins A, D, E, and K can only be digested and used by the body in the combination with fats. Healthy fats include such foods as olive oil, flax seeds and nuts. Fats should equal 20-25% of your total caloric intake.

Protein:

At least 1 gram of protein per pound of bodyweight is recommended for a weightlifting routine, protein aids in the building and repairing of your muscles. Healthy forms of protein include fish, lean red meat, poultry, protein shakes, eggs and skim milk. Protein should equal 35-40% of your total caloric intake.

PROTEIN CALCULATOR

Carbohydrates:

Carbs aid in the immediate usage of energy. Carbs require less water to digest than fat and proteins; therefore they are the most commonly used energy source in the body. Healthy forms of carbohydrates would be foods such as wheat bread, brown rice, oatmeal and nuts. Carbohydrates should equal 40-45% of your total caloric intake.

Calories:

Total calories can be roughly calculated by multiplying your body weight times 15. Then consider these factors:

If Bulking:
Consume 6-8 balanced meals with a total of 500-1000 excess calories.

If Cutting:
Consume 6-8 small balanced meals with a total deficit of 500-1000 calories.

Sleep:

The right amount of sleep is also needed, 7-8 straight hours is required to repair your muscles adequately and for your CNS (Central Nervous System) to recover.

The Central Nervous System.
The human central nervous system consists of the brain and spinal cord. These lie in the midline of the body and are protected by the skull and vertebrae respectively.

This collection of billions of neurons is arguably the most complex object known.

The central nervous system along with the peripheral nervous system comprise a primary division of controls that command all physical activities of a human.

Neurons of the central nervous system affect consciousness and mental activity while spinal extensions of central nervous system neuron pathways affect skeletal muscles and organs in the body.

Also avoid drinking anything 2 hours before you go to sleep, use the bathroom right before bedtime, cut out all lights in the room, loosen and relieve any pressure you may have on your bladder before bed, do not take a nap in the day and relax yourself, as to not worry about any days' events.


Question
What Is Your Favorite Isolation Exercise? Why?

Hands down, my favorite isolation exercise is smith machine shrugs. I like it the best for a number of reasons. One reason is that using the smith machine for shrugs eliminates the need for balancing the bar. This is a great help as your body, forearms especially, can hold the bar up longer because of the support. This allows you to totally concentrate on lifting the weight with your traps.

The Smith machine also has the perfect slant to it. This slant gives you a little more range of motion than you would have with just a barbell. This is because when using a barbell you cannot put your legs slightly past the barbell and slightly arch your back backward. On a smith machine this is possible, thus making the exercise safer and more efficient.

Another reason the smith machine shrug is my favorite exercise is because I see the most benefit from it. It is the best mass builder out of both isolation and compound work for your traps. It's awesome to be able to flex your huge traps gotten from the Smith machine shrugs. I believe traps are one of the most noticed muscles on someone, even with their clothes on, and a much needed muscle to complete your physique.


Question
What Are Some Of The Benefits Of An All Isolation Workout?

-> Completely Exhausting A Muscle:

    • This is the most well-known benefit of isolation work. Compounds work multiple muscles at once, yet it is impossible to work each of those muscles to its max with a single compound exercise. One muscle will tire out before the other. Thus the only way to get a complete workout with compounds would be to do a compound exercise for every muscle in your body. And that is not feasible due to energy and time.

  • This is where isolation work shines, each muscle can be worked to its maximum potential that does not take an extreme amount of time or more energy than one has.

-> Less Opportunities For Injuries:

    • Injuries can arise in all types of workouts, but they are much less common in isolation exercises. This being because compounds are more intense than isolations. They use several muscles in conjunction at once, which greatly opens the door for one muscle overpowering another, thus resulting in a pulled muscle. Another reason is often compounds require you to place great strain on your body.

  • Examples are the "Big 3": squats, deadlifts and bench press. Squats and deadlifts put a great deal of pressure on your spinal column while bench press puts pressure on your chest and shoulders at once, often contributing to a pulled muscle if the barbell slips.

-> Targeting Every Muscle:

    • There are some muscles that you would actually have to work longer and harder just to hit with compound exercises. This is where isolation work helps, it enables you to work a muscle that is hard to hit with compounds.

  • An example of this would be calves. With only using compound workouts, one would have to perform extra sets of squats or lunges to target the calves. Then even at that point they would not get worked nearly as much as a few simple sets of calf raises.

-> Bringing Up A Lagging Body Part:

  • Part of being a bodybuilder is having the ability to have your muscles in proportion to each other. Add in the fact that if a certain body part overpowers another, you are opening yourself up for an injury. Plus the fact that your body grows in proportion to itself, meaning it will be harder for the rest of your body to grow if you have some body parts lagging. Isolation work allows you to target a specific muscle if it is lagging behind, in order to build it up to match your other muscles.


Question
What Are Some Negative Aspects Of An All Isolation Workout?

-> Slower Strength Gains Compared To Compounds:

    • Compound exercises use multiple muscles at once combined with the movement along two or more joints. When your muscles work in conjunction with each other, it better conditions them for strength gains. This is why powerlifters mainly just do compound work. Isolation exercises do not work multiple muscles at once the way compounds do, which is the reason for slower strength gains when doing isolations.

  • Also isolation exercises are not normal movements for our body for the most part. A straight-arm pull-down, which works your lats, is rarely ever used in real life. However a pull-up, which also works your lats, is used in real life for such things as hoisting yourself on to something. The same principle applies to leg extensions, which work your quads. Rarely will you ever do something in real life that resembles a leg extension. However a squat, which also works your quads, is used many times a day for standing yourself up.

-> Longer Workouts:

  • The isolation benefit for a more complete workout does have a price. An isolation workout will last a good deal longer than a compound workout due to the fact that a separate set must be done for every body part. In a compound workout you may work three muscles at the same time, combining muscles in 1 workout.

-> More Effective Exercises For Some Body Parts:

  • Even though for the most part isolations will work a muscle better than compounds, there are some exceptions. Squats are an example. No matter how many sets of leg extensions you do, they will not equal up to a few sets of squats. Squats put constant resistance on your quads the entire time, and use your entire legs to hoist the weight back up. Leg extensions only require you to push weight up with just your quads and they do not place a constant resistance on your legs like squats do.


Question
Who Would Benefit From Using An All Isolation Workout?

The people who gain the most benefit from an all isolation workout would definitely be bodybuilders. Bodybuilding competitions are not judged by the competitor's strength or time spent in the gym. Isolation work is required to keep your body in symmetry. A bodybuilder can build an outstanding physique with only isolation work. No other weightlifter or athlete can benefit more from an all isolation workout.

While bodybuilders have the most benefit, there are others who would benefit from an all isolation workout. These would be older people who may not have the strength or bone support to do squats, deadlifts, bench presses, or pullups. Also for the inexperienced weightlifters, who may not know correct form for the big compound exercises or have enough strength to perform them, would benefit from an all isolation routine.

There are not many people that can do pullups on their first day in the gym or can do a set of squats in proper form. An isolation workout would give these people an introduction to weightlifting before they start doing the more advanced exercises. Whatever the reason, an all isolation routine has its place in weightlifting.

That concludes my article. I hope everyone has enjoyed it and gained some knowledge that you may have not known. I also expect my article to open the people's minds who believe isolation work is useless; so they realize that isolation work can and should be included in your routine to complete it.

Introduction

Isolation movements are excellent for targeting specific muscles. They are used in order to develop a muscle to its fullest potential. Take the biceps for example. You can do countless pullups and barbell rows that will hit your biceps somewhat, but if you crave for that extreme muscle development you must do curls and isolation movements that will hit them to the max and in return give you super-man arms.

To sum it all up, isolation movements are exercises that target one muscle and work little to no secondary muscle groups.


Question
What Is The Best All Isolation Workout? Be Specific.

Compound movements are a smart part of every routine. But without isolation bodybuilders and even power lifters won't be as strong or as muscularly developed as they are. Isolation movements are important in a workout routine.

I believe that in order to achieve the maximum size possible, one must include compound movements such as squats and deadlifts into their workout. But sometimes people have injuries or are rehabilitating and are unable to. This is where this all isolation workout comes in. If you are feeling over-trained or too sore you can also do this workout and take a break from compounds.

Question
What Is Your Favorite Isolation Exercise? Why?

My favorite isolation exercise is the concentrated bicep curl. It's one of my favorites for numerous reasons. First off, that's the very first exercise that hooked me on bodybuilding. I was watching Pumping Iron and when the scene where Arnold was performing the exercise came up I froze.

All I could remember was his huge arms and a vein the thickness of an electrical cord going down them. I was stunned. I wanted to look like that!

Aside from that, this exercise delivers great blood flow to the muscles and in return gives me a great pump. It makes the arms expand and it stretches out the muscle fibers. It's a great exercise that should be in everybody's arm routine. It delivers solid gains and it's fun for me to add weight as I progress. I remember that I started out with only 20 pounds but now I'm up to a solid 50-pound dumbbell and it keeps climbing!


Question
What Are Some Of The Benefits Of An All Isolation Workout?

The best benefit delivered from an all isolation workout is the results! Put in simpler terms, it will give you maximum muscle growth. When body parts are neglected they won't be able to grow. Isolation movements give you the ultimate edge. You get to hit the muscle group that couldn't be hit with compound movements, or it wasn't hit as good and that's why it's lacking.

Take calves for example. Many people suffer from the 'chicken leg syndrome.' Even if their quads and hammies are developed excellently, their calves look like toothpicks. Many will complain that their genetics suck, or that they haven't played soccer when they were youngsters and that's why their calves aren't developed.

If you ask them what they do many will give you their leg routine: squats, leg presses, extensions, curls and maybe 2-4 sets of calve raises at the end, maybe. That's where the problem lies folks. You can't get big calves by doing squats. Unless you are genetically gifted in that area you must isolate the calves with a decent amount of sets. That's where isolation workouts come in, and that's when results happen!


Question
What Are Some Negative Aspects Of An All Isolation Workout?

-> Less Power

    If you are performing an all isolation workout all the time you won't have the chance to experience the great results that come from compound movements such as squats and deads. By doing so your body won't be as powerful as it could have been. As you increase your squat or dead your total body strength also shoots up, and that's a big thing to miss.

-> Less Muscle

    Isolation workouts are perfect for putting the finishing touches or making that stubborn body part grow. But if you are not taking advantage of compound movements you won't be able to get as big as your body could have been. Exercises such as squats will make your whole body grow because they put tremendous stress on a lot of muscle groups at once. More stress means more muscle fibers being torn, which translates to more total muscle gained.

-> HGH (Human Growth Hormone)

      As you put tremendous stress on your body by having a lot of compound lifts your body releases more

HGH

    to build up the muscle. In return you will feel more energized, you will recover way faster than before, and most importantly your body will grow. If you follow an all isolation workout all the time you won't be able to cause that much stress on your body for that rich supply of natural HGH.

-> Weaker Joints

      Since you won't be doing any compound lifts your joints, tendons and ligaments won't be under any big stress. As you progress with the isolation movements you will get stronger muscles without having your joints and tendons catch up to the level where you muscle is at. With that being said the chances of

injury

    of when you do attempt to do compound lifts get very high.


Question
Who Would Benefit From Using An All Isolation Workout?

Bodybuilders are the first on the list that can benefit from an all isolation workout. The reason is simple. When competing, bodybuilders must display a high level of muscularity. In order to do that every body part must be developed. You cannot develop everything perfectly just from compound lifts alone, and that's where isolation work comes in to play.

By isolating each muscle you can get it to grow to its maximal potential and in return be very muscularly developed. Body parts such as calves, rear delts and biceps are examples of what can happen when isolation exercises are allowed in the routine.

Along with bodybuilders many athletes can benefit from an all isolation workout. Every athlete has a sport in which one body part is used more often than the others. By isolating that and making that muscle even stronger and more developed an athlete increases the odds of being better than the opponent.

An example of this is a basketball player with huge calves that increase his/her vertical jump or an baseball player with bigger and stronger forearms for the ultimate grip.

In conclusion, isolation workouts are important and should be in everybody's routine! It will help bring up all the lacking parts that you couldn't grow otherwise and maximize your muscle potential.

Good Luck!
