Squat to Lunge
To do the Squat to Lunge, start with your feet about hip-width to shoulder-width apart. Squat down, sitting your butt back. Do not round forward as you squat down. Keep your heels down and sink your butt so that your quads are about parallel to the ground.
Then jump up and switch into a lunge stance as you land. One foot will be forward and then other will lunge back as you drop your back knee down toward the ground. Sink low in the low and keep your chest up.
In the lunge, your front heel should be down and your weight should be fairly centered.
Jump back into the squat and then lunge on the other side. Move quickly, exploding up off the ground to switch.
Beginners can start with stepping between the two moves instead of jumping.
