Single Arm Plank Rotation With Knee
To do the Single Arm Plank Rotation With Knee, set up in a side plank position from your hand with your bottom leg in back of your top leg.
Then lift that back leg as if kicking it back and up toward the ceiling slightly. Reach your top hand out in front of you and overhead. Your chest will rotate toward the ground as you lift up into this side plank position with your opposite arm and leg raised.
Rotate your chest back open as you tuck your raised leg under and forward, driving your knee forward as you tuck your raised arm down to meet it. Try to touch your knee to your elbow as you rotate your chest back open and away from the ground.
After slowly tucking the knee to the elbow and feeling yourself pivot around that shoulder. The muscles around your rib cage should really be working. Then kick the leg back out and reach back out and overhead with your hand.
Move slowly to stay balanced and try to keep your hand on the ground under your shoulder.
Beginners can tap the toe down behind them or even just do the knee tuck without the kick out.
