Start with your body balanced on your forearms (or palms) and toes. Do not allow your back or legs to drop or curve. Maintain for 30 seconds, 2-3 times. Attempt different plank modifications: first on palms, then forearms, then side plank. Each session should last at least 2 minutes. Do not execute if you have had recent operations, tendon issues, organ swelling, or cardiac or vascular problems.
