What one leg carries when the other comes off the floor
Split your body weight evenly across two legs and each leg carries half of it; stand on one leg and that leg carries all of it. A single-leg squat is therefore twice the per-leg load of a two-leg squat, and matching it on two legs means adding weight equal to your body weight. This page runs that conversion and lays out your box height stages.
These figures are simple arithmetic on body weight, not force-plate measurements. In practice the force through the floor rises or falls with descent speed, torso lean and where the free leg is held. As of October 2026 no published chart defines the stage transitions for a single-leg squat, so you enter the box heights you actually use and the tool only works inside that list.
Stages are sorted from the tallest box down, with the drop from the previous stage alongside. Reps and sets are not prescribed. Lowering on one leg makes a loss of balance easy, so work where one hand can reach a wall or door frame, and see a clinician if your knee hurts.
Frequently Asked Questions
By simple arithmetic on body weight, yes. It is not a force-plate measurement, and the force through the floor shifts with descent speed and posture.
No published standard is available. Enter the heights you actually use and the tool reports the number of stages and the gap between them.
No. It converts load and lays out box height stages only; rep and set prescriptions are not included.
