When you eat and what you eat is very important when you are working out. It is best to eat about an hour or two before your workout and a half hour after.
If you are an early riser and you want to get your workout done first thing in the morning I would suggest a light carb like an apple and maybe a smear of almond or peanut butter. This will give your body the quick and sustained energy to accomplish your work-out.
An important part of your post-work-out nutrition should be a high-quality protein something lean like eggs or chicken. If you work-out in the evening it would be perfect if you could add in fish or chicken to your dinner, your body always needs to recover with a good protein and a high-fiber carbohydrate.
Your body did the work. It feels great! Now reward it with super nutritious foods to help it grow strong.
