Source Free Exercise DB · 2026-07-10
Upper Back-Leg Grab 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 Upper Back-Leg Grab Data Reveals · DOC · STATIC/PATTERN
Upper Back-Leg Grab 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.
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.
Upper Back-Leg Grab catalog footprint
Among 79 exercises whose primary muscle is hamstrings, Upper Back-Leg Grab 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. Upper Back-Leg Grab 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
- While seated, bend forward to hug your thighs from underneath with both arms.
- Keep your knees together and your legs extended out as you bring your chest down to your knees. You can also stretch your middle back by pulling your back away from your knees as your hugging them.
Common mistakes
- Rushing through reps before the pattern is grooved - at this stage, a slow, controlled tempo (2-3s down, 1-2s up) on Upper Back-Leg Grab 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 Upper Back-Leg Grab is what most reliably separates effective reps from wasted ones.
- Using momentum instead of muscle, isolation movements like Upper Back-Leg Grab 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 Hamstrings and secondarily lower back, middle back
- 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 Upper Back-Leg Grab 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/PATTERN · FLOOR
- On STATIC/PATTERN hamstrings work, warm up 5–10 minutes before loading Upper Back-Leg Grab; 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 upper back-leg grab
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 an isolation movement, use it to target the hamstrings 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.
