One Arm Stable Switching Plank

" One-arm stable switching plank: Come down into a plank with your palms chest-width apart on the floor, pulling your abs and squeeze your glutes. Now, inhale as you shift your weight to your right arm and rest your left arm on the outside of your left thigh. Stay up for two counts, then exhale and switch sides, shifting your weight to your left arm as you place your right hand on your thigh and hold for two. Keep alternating sides until you've done this five times on each side. The second time you do this exercise, do a side plank, rotating your upper body to the right side while extending your left arm over your shoulder. Hold for two counts. Return to center and switch sides, rotating and extending your right arm above your shoulder. Keep alternating sides, holding each position for two counts until you've done this five times on each side. Remember to inhale when you move to one side and exhale when you come back to center. The third time you do this exercise, do with a push up in between each side plank. Rotate your upper body and extend your arm over your shoulder. Hold for two counts. Return to the full plank position and do a push up. Then, rotate to the other side, again extending your arm above your shoulder and hold for two counts. Return to the full plank position and do a push up. Keep alternating sides, holding each position for two counts and doing a full push up in between until you've done this five times on each side. Remember to inhale when you move to one side and exhale when you come back to center. This move works your arms and chest, your core, and your glutes. "
