The sit to stand exercise turns getting out of a chair into a movement you can practise deliberately. This guide covers the basic technique and explains how exercise practice differs from a timed chair-stand assessment. If rising without your hands is too difficult, a supported version may be a more useful starting point.
Why one ordinary movement gets so much clinical attention
Standing up from a chair asks a lot of the body at once. The quadriceps and gluteal muscles supply most of the force, the trunk leans to carry your weight forward over your feet, and your balance system manages the handoff from a stable seated base to a narrow standing one. That is why therapists use the movement as both treatment and measurement. The Rehabilitation Measures Database maintained by the Shirley Ryan AbilityLab describes the 30-second chair stand as a measure of functional lower-extremity strength in older adults, built on age-group norms published by researchers Rikli and Jones in 1999. Few exercises train strength, balance, and confidence in one movement that transfers this directly to daily life.
How to do the chair sit-to-stand
Use a sturdy chair that will not slide, ideally backed against a wall. Sit toward the front of the seat with your feet flat and about hip-width apart, heels slightly behind your knees.
- Cross your arms over your chest, or reach them forward as a counterbalance if you need one.
- Lean forward from the hips, nose over toes, then press through your heels to stand.
- Come all the way up, hips and knees fully straight, before you sit back down.
- Lower yourself with control instead of dropping; the slow descent is half the exercise.
Two common mistakes are stopping short of a full stand and collapsing backward into the seat. Both trim away the portions of the movement that do the most work.
Assessment context: the 30-second chair stand
The following numbers describe a standardized assessment, not a target pace or repetition prescription for your exercise sessions. Changing seat height or using your arms changes the task, so supported practice should not be compared with these norms. Have a clinician supervise an assessment if your balance or ability to rise is uncertain.
The CDC includes a standardized version of this movement in STEADI, its fall-prevention initiative for older adults. On the 2017 assessment sheet, the setup is a straight-backed chair with a 17-inch seat and no armrests, arms crossed at the chest, and a count of how many full stands you complete in 30 seconds; if you must push off with your arms, the test stops and is scored zero. The sheet lists below-average scores by age and sex, including:
- Ages 60 to 64: fewer than 14 stands for men, fewer than 12 for women.
- Ages 70 to 74: fewer than 12 for men, fewer than 10 for women.
- Ages 80 to 84: fewer than 10 for men, fewer than 9 for women.
By the CDC's scoring, a below-average result indicates a risk for falls. For context from the other end of adulthood, a 2022 study in the International Journal of Sports Physical Therapy found that healthy adults aged 18 to 35 averaged about 33 repetitions. A low score is a screen, not a diagnosis. It flags that leg strength and balance deserve attention, and your clinician can decide whether and when a repeat assessment would be useful.
If a full sit-to-stand is too hard right now
Struggling with the movement is information, not failure, and it scales down gracefully. Physical therapists usually adjust one variable at a time.
- Raise the seat: a firm cushion or a taller chair shortens the distance you travel.
- Use your arms: pushing off armrests or your thighs is a legitimate starting point that gets retired gradually.
- Counter-supported mini squat: stand at a kitchen counter, hold on lightly, bend your knees a few inches, then straighten. Same muscles, smaller range.
- Countertop squat: as the mini squat gets easy, sink deeper, toward chair-seat height, with your hands resting on the counter for balance.

Making it harder without making it reckless
Progression uses the same knobs in reverse: a lower seat, a slower three-to-four-second descent, arms crossed instead of assisting, a weight held at the chest, or simply more repetitions. A common starting point is 8 to 12 repetitions for one to three sets, several days a week, but the right dose depends on your strength, your joints, and the goal of the exercise, which is what your physical therapist or clinician tailors. If a version starts to feel easy, mention it at your next visit rather than changing several things at once.
Stop if you feel sharp joint pain, chest pain, or dizziness. Set up for safety before testing yourself: a stable chair backed against a wall, and someone nearby if your balance is uncertain, which is why the CDC has assessors stand next to the patient. If you cannot rise without using your arms, or your score sits well below the range for your age, bring that to your physical therapist or clinician rather than treating it as a project to fix alone.
