Overview

The sit-to-stand is a simple way to practise the same basic pattern used for getting out of a chair, climbing stairs and squatting. Chair height makes the exercise easy to adjust: a higher seat asks less of the knee, while a lower seat increases the range and demand.

Primary Purpose

Build quadriceps and hip strength
Improve control while bending and straightening the knee
Create a measurable starting point before progressing to deeper or loaded squats

Equipment Required

A stable chair or bench that will not slide
Optional sturdy counter, rail or support

Step-by-Step Instructions

Sit near the front of a stable chair with both feet flat.
Place your feet about hip-width apart and close enough that you do not need to rock forward aggressively.
Lean your trunk forward slightly and press through both feet.
Stand smoothly without letting either knee collapse inward.
Pause, then reach your hips back and lower to the chair under control.
Begin with 2 sets of 6–10 repetitions.

What You Should Feel

The thighs and hips should do most of the work. Mild knee discomfort may be tolerable for some people if it remains stable and settles afterward. Stop if pain becomes sharp, the knee catches or it feels likely to give way.

Common Mistakes

Dropping quickly onto the chair
Pushing mainly through one leg without intending to
Letting the knees collapse inward
Starting from a chair so low that every repetition provokes increasing pain
Adding weight before the body-weight version is controlled

Easier Alternatives

Use a higher chair or firm cushion
Push lightly through a counter or armrests
Reduce the number of repetitions

Progressions

Lower the seat slightly
Slow the lowering phase to three seconds
Add repetitions, then another set
Hold a light weight close to the chest

Change one variable at a time and use the knee's response later that day and the next morning to judge the dose.

Who Should Avoid This

Do not use this as self-directed rehabilitation after a major recent injury, surgery or suspected fracture unless you have been cleared to load the leg. A locked knee, rapid swelling, inability to bear weight or repeated giving way needs assessment.
