Box Squat
The Box Squat is a squat variation performed by sitting down onto a box or chair under control and standing back up. Because it standardises depth and takes away the fear of falling, it is regarded as one of the safest ways to learn squat technique.

Why work with a box?
The box makes every repetition descend to the same depth, and it means there is a safe target beneath you even if your balance goes. Those two features solve the two problems seen most often when people learn to squat: reaching a different depth each time, and being reluctant to sit back. Because the height of the box can be adjusted, the movement adapts easily to whatever range of movement you currently have.
Sit down, or just touch?
Both approaches are used. Early on, sitting fully onto the box for a moment and standing up while keeping trunk tension helps develop control. As you progress, touching the box lightly and standing again keeps depth honest without breaking the rhythm. Either way, the point is to meet the box softly rather than collapse onto it.
What comes next?
Gradually lowering the box makes the movement harder in a natural way. Once the free bodyweight squat feels comfortable, the loaded Goblet Squat is a sensible next step.
