How to do it

Hack squat variation with one leg forward that concentrates more load on the working side while keeping a guided path.

Form. Plant the working foot firmly, use the other only as light support and descend without losing knee and hip alignment.

Common mistake. Turning it into a bilateral rep, loading too soon, locking the knee at the top, or lifting the heel of the main leg.
