The Zercher squat can build quads better than the front squat. It can jack up your traps better than shrugs. It can give you a core of steel faster than most ab work. It can even give you bigger biceps.
But you probably aren’t doing it because:
It’s brutally hard.
You don’t know how effective it is.
You’ve never seen it done.
If you can push through the discomfort, this exercise – along with all the other Zercher variations – can completely transform your physique.
