This is a fun one. Here’s how you do it:
Balance on the back of your glut muscles.
Lift your feet of the ground and place your hands at your ankles or behind your thighs
Hold your balance and then rock you pelvis back and roll back to your shoulders (try to keep your head tucked toward your chest and keep your head from hitting the floor).
Roll back up and balance in the same place you started.
Try not to let your feet hit the floor when you come back up.
Also, try to keep your shoulders from crunching up to your ears.
The slower your roll, the harder it will be! It will be easier if you try and keep your spine in a C-shape. Hense the name Rolling-Like-A-Ball. That curve will make it easier to get back up.
Have fun, enjoy it and let yourself feel like a little kid again.
