Feet hip width or slightly further apart. Feet pointing forwards or just slightly turned out. Keeping back flat and head facing forward, bend knees until upper and lower legs are at 90 degrees. Ensure knees travel in line with feet and heels remain flat to the floor throughout. Avoid locking the knees when legs are straight.

From the lowest point jump up and tuck your knees up to your chest.
