It's one of those things that only the REALLY dedicated lifters do. The Zercher squat is as effective as it is painful. Try it.
Target your hips and hams with this type of squat. It'll help you get out of the hole when you squat without a box.
Build and strengthen your entire posterior chain. Do this twice per week, 5 trips of 40 yards, bodyweight or close to it on the sled.
The cable pull-through is great for glutes, and it's a favorite for boosting squat and deadlift strength. Now try it with a band. Shoot for 100 reps at the end of leg day.
