It’s best not to work out right after eating. But how long should you wait before you get active? Try to wait about 30 minutes after you eat a snack. Wait about 2 to 3 hours after you eat a small meal. And wait about 3 to 4 hours after you eat a large meal. If you wait the right amount of time after eating to work out, it may help you avoid cramping or other digestive problems.

Make sure to talk with your doctor before starting any new fitness routine.
