What should I look for in a basic squat?
Look for stable feet, coordinated bending of hips and knees, a controlled descent and a balanced return to standing. A stable chair provides a clear target for learning the sit-to-stand version. Depth and stance vary with the task and person; forcing a universal shape is less useful than preserving control.
Chair rise: follow the change in support
A seated start, a controlled transfer onto the feet, and an upright finish. Chair height and body angles are illustrative.
Start seated
Use a stable chair without wheels. Place both feet on the floor and organise a comfortable base.
Transfer and rise
Lean forward under control, then straighten the hips and knees. Hand support may help when needed.
Stand, then return
Finish upright. Reverse the movement and return to the seat gently instead of dropping onto it.
Original movement schematic; sequence informed by NHS. A schematic for understanding a general movement, not an individual technique assessment or training prescription.
Set up a reliable base
Use a stable chair without wheels on a surface where it will not slide. Sit toward its front with feet on the floor, roughly hip-width apart. The feet should be positioned so they can accept body weight as the trunk moves forward. In the NHS version, lean slightly forward and use the legs to rise; arms may help when necessary. An unsupported squat begins standing, with a comfortable stance around shoulder width and toes straight ahead or modestly turned out. These are starting options, not a test of whether everyone can copy a photographed angle.
