Feel like you're short on time? Don't let that deter you from getting in a quality sweat session. Do your best not to cut any corners, but if necessary you can delete the stretch series from the workout. You can work on your flexibility later in the week.
Remember that working out is only part of the equation; you have to eat clean to see results. Simple nutrition is the best because it's maintainable. Healthy living doesn't have to be complicated. Stick to your plan of choice and eat for muscle building or fat loss. Make sure to make lean meats, veggies, complex carbs, and healthy fats the basis for your meal plan.
Keep these key principals in mind and you'll be good to go: Eat every three hours and have your first meal within 30 minutes of waking; drink at least one gallon of water with two lemons daily; skip fillers, preservatives, and artificial colorings; and eat gluten- and dairy-free foods (except whey isolates).
