Lie on your stomach comfortably on a flat, supportive surface.
Place your arms above your head, keeping your palms down.
Slowly raise your left arm and right leg off the ground, raising each as high as your flexibility allows. Keep your elbow and knee straight. Then slowly lower your arm and leg to the starting position to complete one repetition. Repeat 9 more times to complete one set of 10 repetitions.
Repeat the process and perform 10 repetitions while raising your other arm and leg.
You’ve completed this one! Great job!
