How long should a jump rope be for my height?
Stand on the center of the rope with one foot and pull the handles upward they should reach your armpits for beginners, or chest height for more advanced jumpers. Most adjustable ropes come in a 10 foot length that can be shortened to fit. A rope that is too long will drag and catch on the ground, while one that is too short forces you to jump higher than necessary, wasting energy and breaking your rhythm.
