15. Iron Mikes
Stand upright with your chest slightly lifted, feet hip-width apart, toes pointing straight forward.
Place your hands on the back of your head to the back of your head with your elbows pointing to the side.
Lunge backward with your right leg and place your toes on the floor. Do not pull your head down with your arms.
In the down position, the knee of your front foot must be directly above the ankle. Now jump into the air and switch the two legs to be back in the lower lunge position.
