Instructions
Lay on a mat with your arms flat by your sides and your glutes, hamstrings, and calves all resting on a Swiss ball.
Pull your heels into the Swiss ball allowing you to ‘grip’ the ball between your heels and glutes.
Putting pressure on your arms, roll your lower body back so that your glutes and lower back leave the ground with the Swiss ball held tightly.
Lower your back and glutes slowly back to the ground to complete one rep.
