The verdict
Knee Tuck Jump has 3-step instructions, documented to a similar depth as most of the 79 hamstrings exercises PlainExercise catalogues.

Source Free Exercise DB · 2026-07-10
Knee Tuck Jump is documented from the Free Exercise DB (CC0) extract, last ingested July 2026. Classification, muscle roles and instruction text are source facts; the placement and cohort measures on this page are computed by PlainExercise and are not a rating of the movement.
What the Knee Tuck Jump Data Reveals · DOC · PUSH/COMPOUND
Knee Tuck Jump stands out on force direction, the first filter on this record.
A short step list is a thin upstream record, so taxonomy badges carry most of the page identity.
Across 79 catalogued hamstrings movements, the average instruction record is 621 characters and 3.9 steps; 41 of those (51.9%) clear the same ≥500-character rich bar used here. This page ranks #40 of 79 by instruction-character length (84.6% of the cohort average).
Among the 111 exercises that also use just bodyweight, average instruction length is 581 characters; 59 of those peers are longer than this record. Equipment-matched peers are the honest comparison when you are choosing a substitute implement for the same pattern.
Other well-documented hamstrings movements (same ≥500-character bar):
- Power Clean (24 steps, 3,264 chars)
- Clean (6 steps, 1,688 chars)
- Power Clean from Blocks (5 steps, 1,423 chars)
- Split Snatch (6 steps, 1,289 chars)
- Power Snatch (5 steps, 1,116 chars)
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.
Knee Tuck Jump catalog footprint
Among 79 exercises whose primary muscle is hamstrings, Knee Tuck Jump ranks #29 by catalogued variation count. The upstream file attaches 2 images to this slug. See the step-count ranking for hamstrings for peer documentation depth.
Muscles worked
The Free Exercise DB classifies each muscle 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. Knee Tuck Jump 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
- Begin in a comfortable standing position with your knees slightly bent. Hold your hands in front of you, palms down with your fingertips together at chest height. This will be your starting position.
- Rapidly dip down into a quarter squat and immediately explode upward. Drive the knees towards the chest, attempting to touch them to the palms of the hands.
- Jump as high as you can, raising your knees up, and then ensure a good land be re-extending your legs, absorbing impact through be allowing the knees to rebend.
Common mistakes
- Rushing through reps before the pattern is grooved - at this stage, a slow, controlled tempo (2-3s down, 1-2s up) on Knee Tuck Jump teaches the nervous system the movement far faster than speed does.
- Cutting the range of motion short - moving the hamstrings through its full safe range on Knee Tuck Jump is what most reliably separates effective reps from wasted ones.
- Treating a compound lift like an isolation movement - Knee Tuck Jump recruits multiple joints; bracing the core and engaging stabilizers matters as much as the prime movers.
- Flaring elbows excessively on push movements, tucked elbows protect the shoulder joint and transfer more force into the target muscles.
- Breathing out of sync with the lift on Knee Tuck Jump - brace and inhale during the lowering phase, exhale on the exertion, especially important with just bodyweight where control matters most.
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 Hamstrings and secondarily abductors, adductors
- People training at home without equipment
Who this is NOT for
- People hunting equipment swaps, this record has none to offer; browse the peer hamstrings 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 Knee Tuck Jump 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 · BODY-ONLY · PUSH/COMPOUND · FLOOR
- On PUSH/COMPOUND hamstrings work, warm up 5–10 minutes before loading Knee Tuck Jump; 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 BODY-ONLY 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 knee tuck jump
Three ways to put it to work.
- Train the hamstrings 2–3 times a week with 48+ hours between hard sets; pair this with other hamstrings movements for balanced development. All hamstrings 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.
