Swiss ball reverse hyperextension x 20
Tips:

Hands on the ground, directly underneath the shoulders, hips on top of the ball and toes touching the ground so you are forming an inverted V with your body.

Legs wide, turn the toes out and flex the feet.

Squeeze your butt at the top of the movement for two seconds before lowering with control to touch and go again.
