The verdict
One Knee To Chest has 4-step instructions, more thoroughly documented than most of the 22 glutes exercises PlainExercise catalogues.
Ranked against the 22 glutes exercises PlainExercise currently catalogues, not the full exercise-science literature.
One Knee To Chest is a beginner compound movement that trains the Glutes along with hamstrings and lower back. There are 0 known variations and 8 peer exercises that target the same primary muscle.
- 1 of 9 exercises targeting the Glutes
- Level: beginner
PlainExercise cross-links 0 variations and 8 peer exercises sharing the same primary muscle.
What the One Knee To Chest Data Reveals
One Knee To Chest is classified in the PlainExercise database as a beginner-level compound movement with a static force profile, primarily training the Glutes with secondary engagement of the hamstrings, lower back. The canonical form is bodyweight-only and needs no equipment, and the movement falls within the stretching category. The parent record is sourced from the public-domain Free Exercise DB and enriched with exercise-science framing unique to PlainExercise, including structured common-mistake patterns derived from the force and mechanic fields above.
Within the same primary-muscle cohort, the Glutes is trained by 9 catalogued movements in total, meaning any practitioner planning a session has at least 8 alternatives that load the same tissue through different joint angles or equipment profiles. No alternate-equipment variations have been catalogued for One Knee To Chest yet; the canonical form is the documented path. The documented execution runs 4 discrete steps, each one derived directly from the upstream record and reproduced verbatim rather than paraphrased.
Context matters: this database aggregates exercise science taxonomy (level, mechanic, force, primary/secondary musculature, equipment) but does not and cannot account for individual biomechanics, joint history, recovery status, or training context. The common-mistake and progression framing below is derived programmatically from the classification fields and represents general exercise-science consensus rather than case-specific coaching. This is not medical or personal-training advice. Consult a physician, physical therapist, or certified trainer before starting a new exercise or modifying an existing program, particularly if you have prior injuries, pain, recent surgery, cardiovascular limitations, or are pregnant.

Muscles worked
According to the Free Exercise DB classification, One Knee To Chest trains the glutes as the prime mover, with 2 muscles assisting. The source classifies muscles as primary or secondary, it does not measure activation, so we show involvement, not percentages.
Source: Free Exercise DB primary/secondary muscle classification. Involvement, not measured activation, actual recruitment varies by load and form.
Intensity context
For reference, here is where common activities sit on the MET intensity scale. One Knee To Chest does not have a measured MET in the source data, its intensity depends on the load and effort you use. Estimate calories for any activity with the calorie calculator.
MET values from the Compendium of Physical Activities (Ainsworth et al., 2011). A general reference scale, not a rating of this specific movement.
How to do it
- Start off by lying on the floor.
- Extend one leg straight and pull the other knee to your chest. Hold under the knee joint to protect the kneecap.
- Gently tug that knee toward your nose.
- Switch sides. This stretches the buttocks and lower back of the bent leg and the hip flexor of the straight leg.
Common mistakes
- Rushing through reps before the pattern is grooved - at this stage, a slow, controlled tempo (2-3s down, 1-2s up) on One Knee To Chest teaches the nervous system the movement far faster than speed does.
- Cutting the range of motion short - moving the glutes through its full safe range on One Knee To Chest is what most reliably separates effective reps from wasted ones.
- Treating a compound lift like an isolation movement - One Knee To Chest recruits multiple joints; bracing the core and engaging stabilizers matters as much as the prime movers.
- Loading before grooving the pattern, practice the movement with light resistance until the path feels automatic, then add load.
- Breathing out of sync with the lift, brace and inhale during the lowering phase, exhale on the exertion.
Who this is for
- People new to resistance training who want to build a foundation in the movement pattern
- People who want to train the Glutes and secondarily hamstrings, lower back
- People training at home without equipment
Who this is NOT for
- Anyone with acute pain in the joints or muscles involved, pain is a stop signal, not a soreness signal
- People with unresolved injuries in the loaded joints, seek clearance from a physical therapist first
- Anyone with a recent surgery, cardiovascular limitation, or pregnancy complication without physician clearance
Progression path
Once One Knee To Chest feels comfortable with your current load, progress by (a) adding reps until you can complete 12+ per set, (b) increasing resistance by 2.5-5%, (c) moving to harder variations such as single-limb or longer lever versions, and eventually (d) stepping up to intermediate-level movements that train the same muscle.
See the Progression guide for a full framework on when to advance, and the Compound vs Isolation guide to decide when to prioritize this movement in your program.
Safety notes
- Sharp or joint pain is a stop signal. Muscle soreness during sets is normal; pain is not.
- Warm up the involved joints with 2-3 progressively loaded sets before training to a working weight.
- If you have a history of injury in the loaded joints (knees, shoulders, lower back), consult a physical therapist before loading this movement.
- General information only. Consult a physician or certified trainer before starting any new exercise program.

Using the one knee to chest
A beginner compound movement for the glutes - here's how to put it to work.
- Train the glutes 2–3 times a week with 48+ hours between hard sets; pair this with other glutes movements for balanced development. All glutes exercises
- Match the load and rep range to your goal, strength, size, or endurance each call for a different scheme. Strength vs hypertrophy
- As a compound lift, this trains several muscles at once, anchor your session around it before isolation work. Compound vs isolation
Form before load. If a movement causes sharp or joint pain, stop and substitute a safer alternative, this is general information, not medical or training advice.
