a. Start in a split stance with the right leg forward. b. Start slowly lowering the hips with the entire body straight down in to a lunge position. Both legs should form two 90 degree angles. c. Tighten core and swing arms for balance and momentum, jump up and switch legs so that the front leg in the lunge position will now be the left leg. Keep the knees and feet pointed forward throughout the exercise. d. Make sure on every jump and switch, that the legs both come down bent in the lunge position. e. Repeat repetitions, so that both legs are worked evenly.
