Ab challenge - Forearm side plank with medicine ball (core, legs, shoulders, arms)

Begin on the floor on one side, legs straight and stacked on top of one another, and the forearm on the floor with the elbow directly beneath the shoulder. Hold a ball in the top hand and extend the arm to the front while raising the torso into side plank. Slowly lift the ball toward the ceiling while maintaining the side-plank position. Lower the ball and repeat until you have met your desired amount of reps.
