The Single-Leg Squat Press combination exercise works your shoulders, back, triceps, butt and legs.
Standing on one leg, you're gonna first do a shoulder press and then come down into a single leg squat. Now you wanna keep the hand in front of your chest steady so that it provides resistance as you do those shoulder presses. Continue like this for 1 minute then switch legs and repeat. You're going to do 2 sets total.
