The verdict
Ankle On The Knee has 3-step instructions, documented to a similar depth as most of the 22 glutes exercises PlainExercise catalogues.
Ranked against the 22 glutes exercises PlainExercise currently catalogues, not the full exercise-science literature.

What the Ankle On The Knee Data Reveals
Ankle On The Knee is classified in the PlainExercise database as a beginner-level strength movement with a static force profile, primarily training the Glutes. 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 Ankle On The Knee yet; the canonical form is the documented path. The documented execution runs 3 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, Ankle On The Knee trains the glutes as the prime mover and no catalogued secondary muscles. The source classifies muscles as primary or secondary, it does not measure activation, so we show involvement, not percentages.

Intensity context
For reference, here is where common activities sit on the MET intensity scale. Ankle On The Knee 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
- From a lying position, bend your knees and keep your feet on the floor.
- Place your ankle of one foot on your opposite knee.
- Grasp the thigh or knee of the bottom leg and pull both of your legs into the chest. Relax your neck and shoulders. Hold for 10-20 seconds and then switch sides.
Common mistakes
- Rushing through reps before the pattern is grooved - at this stage, a slow, controlled tempo (2-3s down, 1-2s up) on Ankle On The Knee 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 Ankle On The Knee is what most reliably separates effective reps from wasted ones.
- Using momentum instead of muscle, isolation movements like Ankle On The Knee reward strict form. If you're swinging the weight, it's too heavy.
- 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
- 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 Ankle On The Knee 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.

Using the ankle on the knee
A beginner strength 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 an isolation movement, use it to target the glutes directly after your compound lifts. 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.
