Seated Knee Raises (abs)
Seated Knee Raises strongly target the lower abs with a compact range of motion, making them an efficient tool for building a six-pack. Sit on the edge of a bench or chair and lean back slightly, holding the edge for support. Draw your knees up toward your chest using your lower abs, then extend your legs back out without letting your feet touch the floor between reps.

Medicine Ball Straight Leg Raises
Medicine Ball Straight Leg Raises add resistance to a classic lower-ab movement, using the weight of the ball to make bigger gains than the bodyweight-only version. Lie on your back holding a medicine ball between your feet or ankles, legs extended toward the ceiling. Lower your legs slowly toward the floor without letting your lower back arch, then raise them back up using your lower abs.
