A. Any time of the day is good for exercise. Don't workout immediately after a heavy meal. Give at least one hour gap and then exercise. If the meal is a snack then half an hour gap is sufficient.

A. You should always stretch after work out. When you exercise, you increase the tension in the muscles. Stretching helps your muscles to relax. So, stretching before the workout, your muscles hardly get any time to stay in the relaxed state. Moreover, after workout, your muscles are warm which reduces the risk of injury due to stretching. Never stretch a cold muscle.

Carbohydrate will help to restore depleted glucose-stores, and protein will help in recovery and growth of muscles.

A. It is advisable to follow 1 : 2 : 3 ratio of Fat : Protein : Carbohydrate in your diet under normal conditions.

A. Undoubtedly, protein supplements help in better and fast recovery of muscles.
