What the One Knee To Chest Data Reveals · DOC · STATIC/COMPOUND
One Knee To Chest opens on force profile: a STATIC compound pattern for glutes, force direction is the first filter on this floor-level record.
4 steps land in the middle third (4–5) of the catalogue, enough detail to compare form without the longest upstream essays.
One Knee To Chest is classified 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 in the stretching category. Within the glutes cohort, 9 catalogued movements share the primary target; no alternate-equipment variations are catalogued yet.
Context matters: taxonomy (level, mechanic, force, musculature, equipment) does not account for individual biomechanics, joint history, or recovery. Common-mistake framing below is derived from classification fields, not case-specific coaching. Not medical or personal-training advice. Consult a physician or certified trainer before starting, especially with injuries, cardiovascular conditions, recent surgery, or pregnancy.

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
- People hunting equipment swaps, PlainExercise lists 0 catalogued variations for One Knee To Chest; browse 8 peer glutes exercises for alternate patterns instead.
- 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 · BODYONLY · STATIC/COMPOUND · FLOOR
- On STATIC/COMPOUND glutes work, warm up 5–10 minutes before loading One Knee To Chest; keep first sets light until the path feels automatic.
- Sharp or joint pain is a stop signal. Muscle soreness during sets is normal; pain is not.
- Beginners on BODYONLY gear: cut volume before cutting form, drop a set rather than rush reps.
- 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.
