Hi Anne! Even though the click doesn't hurt, I would consider trying the modified version since it is still very challenging.
Instead of reaching long lever with arms and legs, place the ball between bent knees and crunch up with your upper body to get it. As your arms take the ball and extend back over your head, lower your bent legs toward the ground until your toes touch. Now bring your bent knees back toward your chest, and at the same time, bring the ball up with your arms and place the ball in between your shins/knees. Lower the ball until your toes touch, and at the same time, lower your arms back just as before except without a ball this time.
Hope this helps!
