"For as the body without the spirit is dead, so faith without works is dead also." James 2:26
Recovery is an equally essential component of an exercise program because it gives the body time to repair, rebuild, and strengthen itself between workouts.
Exercising loses lots of fluids. Drink at least half your body weight in ounces to properly replace and rehydrate.
Working out breaks down muscle. You can help repair and rebuild your muscles by consuming proteins with essential amino acids.
When you work out, you burn carbohydrates stored in muscle for energy. You need to replenish it by consuming carbs.
Get some sleep. 7-9 hours os sleep is essential for muscle repair and growth.
