Pistol Squat

The pistol squat is a single-leg bodyweight squat to full depth with the opposite leg extended forward. It builds the maximal unilateral leg strength, balance, and mobility that support HYROX Sandbag Lunge performance and running stability.
Movement and technique
A pistol squat is a single-leg squat with the non-supporting leg held off the floor. The supporting hip, knee and ankle move through a range while trunk and pelvis are controlled. Depth, free-leg position and counterbalance vary. Use a range and assistance that can be controlled rather than forcing one knee path or full depth for everyone.

Scaling and limits
A box, hand support, counterweight or reduced range can scale the task. Progress range, repetitions or load gradually according to strength, mobility and tolerance. The exercise can train unilateral squatting, but a side-to-side difference is not a diagnosis and no timeline or repetition benchmark applies universally. It does not guarantee injury prevention or HYROX® transfer.
