The exercise ball pike is a challenging move that targets the core. It involves thrusting the hips into full flexion over a ball, then extending out to a foot-elevated plank with the feet on the ball. It's a challenging move from a strength perspective, but also for balance. It can be the centerpiece of an ab workout or go along with other body weight or ball movements in an ab circuit.
Works the abs through a wide range of motion
Excellent as low-rep strength training for abs
