The verdict
Lying Bent Leg Groin has 3-step instructions, documented to a similar depth as most of the 13 adductors exercises PlainExercise catalogues.
Ranked against the 13 adductors exercises PlainExercise currently catalogues, not the full exercise-science literature.
Lying Bent Leg Groin is a expert strength movement that trains the Adductors. It requires other equipment. There are 0 known variations and 8 peer exercises that target the same primary muscle.
- 1 of 9 exercises targeting the Adductors
- Level: expert
PlainExercise cross-links 0 variations and 8 peer exercises sharing the same primary muscle.
What the Lying Bent Leg Groin Data Reveals
Lying Bent Leg Groin is classified in the PlainExercise database as a expert-level strength movement with a static force profile, primarily training the Adductors. The canonical form requires other 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 Adductors 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 Lying Bent Leg Groin 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, Lying Bent Leg Groin trains the adductors 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.
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. Lying Bent Leg Groin 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
- Lie on your back with your knees bent and the soles of the feet pressed together. Have your partner hold your knees. This will be your starting position.
- Attempt to squeeze your knees together, while your partner prevents any movement from occurring.
- After 10-20 seconds, relax your muscles as your partner gently pushes your knees towards the floor. Be sure to inform your helper when the stretch is adequate to prevent injury or overstretching.
Common mistakes
- Letting tempo drift under heavy load - even at advanced weights, a controlled Lying Bent Leg Groin rep (2-3s down, 1-2s up) still outperforms a rushed one for muscle tension and joint safety.
- Cutting the range of motion short - moving the adductors through its full safe range on Lying Bent Leg Groin is what most reliably separates effective reps from wasted ones.
- Using momentum instead of muscle, isolation movements like Lying Bent Leg Groin 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 on Lying Bent Leg Groin - brace and inhale during the lowering phase, exhale on the exertion, especially important with other equipment where control matters most.
Who this is for
- Experienced trainees who can load the movement safely and have mastered the progression ladder below
- People who want to train the Adductors
- People who have access to other 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
- Complete beginners, start with the progression ladder below and build the pattern before loading it
- Anyone with a recent surgery, cardiovascular limitation, or pregnancy complication without physician clearance
Progression path
At this stage, progress comes from refining technique, reducing rest between sets, and periodizing intensity across training cycles rather than chasing heavier loads.
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.
- This is an advanced movement. It should be loaded only after you have mastered the intermediate progression, ideally with supervision.
- General information only. Consult a physician or certified trainer before starting any new exercise program.

Using the lying bent leg groin
A expert strength movement for the adductors - here's how to put it to work.
- Train the adductors 2–3 times a week with 48+ hours between hard sets; pair this with other adductors movements for balanced development. All adductors 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 adductors 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.
