Primary Muscle: Abs
Equipment: Bodyweight
Level: Beginner
Purpose: To target the lower abs.
Execution: From a lying position on the floor, place your hands along either side of your body for support and extend your legs. Holding a medicine ball in between your feet, raise your legs up over your body, rolling your pelvis off the floor. Squeeze at the peak contraction and give a strong exhale before returning slowly to the start position. Lower your legs to the point just before your lower back starts to lift off the floor before lifting for another repetition.
