So I am not the proudest of the poundage I am using in these lifts, but I have never been a massive squatter, even though I have spent a large chunk of my life in the weightroom.
Anyways, these squat variations can be a great tool to use in helping you become a more explosive athlete. They have helped me in the last 6 weeks, and I am exited to try them out with my athletes this upcoming season.
In order to get the most out of this exercise, make sure you drive through your heels out of the bottom of the lift, and focus on keeping the weight on your heels at each holding position. This way you will keep the weight back on your hips and glutes as much as possible.
I learned these from Dr. Michael Yessis in one of his training books.
