|Incline Plank - Marching Legs|
The most effective abdominal exercise is the plank - an isometric exercise, requiring you to hold your muscles in a contracted position to maintain stability. When you have mastered the basic plank (you may need to start on your knees), you can try these modifications to target different muscles and add a new level of challenge to your abs routine. How long can you hold?
