The verdict
Thigh Adductor has 4-step instructions, more thoroughly documented than most of the 13 adductors exercises PlainExercise catalogues.
Ranked against the 13 adductors exercises PlainExercise currently catalogues, not the full exercise-science literature.
Thigh Adductor is a beginner isolation movement that trains the Adductors along with glutes and hamstrings. It requires a machine. There are 0 known variations and 8 peer exercises that target the same primary muscle.
- 1 of 9 exercises targeting the Adductors
- Level: beginner
PlainExercise cross-links 0 variations and 8 peer exercises sharing the same primary muscle.
What the Thigh Adductor Data Reveals
Thigh Adductor is classified in the PlainExercise database as a beginner-level isolation movement with a pull force profile, primarily training the Adductors with secondary engagement of the glutes, hamstrings. The canonical form requires a machine, and the movement falls within the strength 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 Thigh Adductor yet; the canonical form is the documented path. The documented execution runs 4 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, Thigh Adductor trains the adductors 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.

Intensity context
For reference, here is where common activities sit on the MET intensity scale. Thigh Adductor 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
- To begin, sit down on the adductor machine and select a weight you are comfortable with. When your legs are positioned properly on the leg pads of the machine, grip the handles on each side. Your entire upper body (from the waist up) should be stationary. This is the starting position.
- Slowly press against the machine with your legs to move them towards each other while exhaling.
- Feel the contraction for a second and begin to move your legs back to the starting position while breathing in. Note: Remember to keep your upper body stationary and avoid fast jerking motions in order to prevent any injuries from occurring.
- Repeat for the recommended amount of repetitions.
Common mistakes
- Rushing through reps before the pattern is grooved - at this stage, a slow, controlled tempo (2-3s down, 1-2s up) on Thigh Adductor teaches the nervous system the movement far faster than speed does.
- Cutting the range of motion short - moving the adductors through its full safe range on Thigh Adductor is what most reliably separates effective reps from wasted ones.
- Using momentum instead of muscle, isolation movements like Thigh Adductor reward strict form. If you're swinging the weight, it's too heavy.
- Shrugging the shoulders up toward the ears on pull movements, keep shoulder blades down and back to load the correct muscles.
- Breathing out of sync with the lift on Thigh Adductor - brace and inhale during the lowering phase, exhale on the exertion, especially important with a machine 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 Adductors and secondarily glutes, hamstrings
- People who have access to a machine
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 Thigh Adductor 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 thigh adductor
A beginner isolation 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.
