The in place inchworm exercise is a dynamic variation of the traditional inchworm that adds an element of hand movement to increase the challenge. Start by standing tall with your feet hip-width apart. Hinge at the hips and walk your hands out in front of you until you reach a plank position, then continue "walking" your hands forward, allowing your body to follow until you've moved a desired distance. Reverse the movement by walking your hands back towards your feet and return to standing, engaging your muscles throughout the motion for a full-body workout that also promotes flexibility and coordination.
