Crunches: Bent Knee (abs)
Crunches: Bent Knee are the classic, tried-and-true ab exercise, effective when you focus on a controlled contraction rather than momentum. Lie on your back with your knees bent and feet flat on the floor. Curl your shoulders and upper back off the floor toward your knees, holding an isometric squeeze at the top for a beat before lowering back down with control.
Medicine Ball Side Planks
Medicine Ball Side Planks firm the whole midsection, with the added ball work making them especially effective for the obliques and overall core strength. Prop yourself up on one forearm in a side plank, hips lifted so your body forms a straight line, and hold or reach a medicine ball with your free hand. Hold the position, keeping your hips square and lifted, then switch sides.
Medicine Ball Pass-throughs
Medicine Ball Pass-throughs use resistance through a large range of motion, hitting both the upper and lower abs on the way to a faster six-pack. Sit with knees bent and feet lifted slightly off the floor, holding a medicine ball. Pass the ball under your knees from one hand to the other, then pass it back over the top, keeping your core braced and your feet off the ground throughout.
