To test and strengthen your balance, try a side plank with a leg raise â get into side plank position, then lift your top leg and hold for one count. Lower it and repeat, then switch sides. In addition, planks work all the muscles you need to maintain proper posture, like your back, chest, shoulders, abs, and neck.
A beautiful thing about the plank is that small changes make the movement much harder to perform. One of the most effective ways to amplify a plank is simply to lift up an arm or foot. By doing this, your body has to work harder to resist instability and rotational force. Start off by holding a good plankâemphasis on goodâwith only one foot in contact with the ground, and then progress to lifting an arm up.
