1. Train Everything
Train every muscle don't skip any muscle because you don't think that it needs to be worked on. Because every muscle supports a muscle. Like if you want a big chest you pecs have to be built and so does your shoulders, triceps, back, biceps, and legs (supports your back.)
2. Free Weights Are Better Than Machines
This point has been proven time after time. Machines only give you 75% of the pump that you would get from a machine. So only use machines for things that you need them for like the lat pull down, or the leg extension or leg curl.
3. Use Proper Nutrition
For an average bodybuilder you should eat 6 meals a day each meal should have the protein range of 20-30 grams. And you should have a lot of carbs before you workout.
4. Rest In between Sets
You should rest for 30-60 seconds in between each set. This gives your muscles just enough rest to keep up with your workout.
5. Use Supplements That Work
If you have been trying supplements out and some don't work for you at all then don't buy it. It isn't worth your money to buy stuff that doesn't work for you.
6. Keep The Cycle Going
This is about training cycles you should always have one planned out for 6-10 weeks at a time these are meant for building mass and for having a game plan for getting in and out of the gym as quickly as possible.
7. Use exercises that work!

You should try to get in at least 1-2 gallons of water a day. This will help wash the lactic acid out of you muscles and will make you feel better. I suggest taking creatine to help you out with keeping water in.
