Muscle groupsBack, Core
DescriptionLie down on your back and start in a hollow body hold position with your arms elevated behind your head and legs elevated over the ground. Keep your core engaged and pressing your lower back into the ground.
Start the movement by lifting your upper body in the same movement as you bend your knees and move your arms up and then sideways.
When you knees are bent and arms are straight to your sides, you can reverse the movement until you are back into hollow body hold position.
Repeat for the required amount of times.
