Thigh Adductor
The thigh adductor machine has you sit with pads against the inside of your thighs, then pull your legs together against resistance. It isolates the hip adductors, the muscles that bring your leg back toward your body's midline, with the glutes and hamstrings assisting. It's a beginner-friendly machine move that needs no balance or coordination beyond pulling and controlling the return.
Why it works
Bringing your leg back toward the midline of your body is the hip adductors' job, and that's exactly the motion the machine resists. Your glutes and hamstrings assist at the hip as the legs come together, so they share a small part of the work. Because the machine's pads move along a fixed path, you can isolate that single inward motion without needing to balance or stabilize the rest of your body.
Set up
- Sit in the machine with your back against the pad and adjust the thigh pads to rest against the inside of your thighs, not your knees.
- Select a resistance you can control through the full range of motion.
- Start with your legs spread to a comfortable, not maximal, width.
- Rest your hands lightly on the handles or your lap, not gripping hard to assist the movement.
How to do it
- Start with your legs spread apart and the pads resting against your inner thighs.
- Pull your thighs together against the pads, bringing your legs toward the midline.
- Pause briefly once your legs come together.
- Return your legs back out under control, resisting the machine rather than letting it snap your legs apart.
- Keep your torso upright against the backrest throughout the rep.
- Reset before starting the next rep.
Form cues
- Control the return just as much as the pull inward.
- Keep your torso still against the backrest, don't lean to help the pull.
- Keep the movement smooth, no jerking at either end of the range.
- Let your hips do the work rather than gripping the handles to cheat the rep.
Breathing: Exhale as you pull your thighs together, inhale as you let your legs spread back out.
Common mistakes
Letting the weight stack snap the legs back apart too quickly.
Fix: Resist the outward return just as deliberately as the inward pull.
Jerking into the first part of the pull.
Fix: Start the movement smoothly and build tension gradually rather than yanking the pads inward.
Setting the pads against the knees instead of the thighs.
Fix: Adjust the seat and pad width so the pads sit on the inner thighs before starting.
Leaning the torso to help pull the pads together.
Fix: Keep your back flat against the pad and isolate the movement to your hips.
How to program it
- 2 to 3 sets of 12 to 20 reps works well for this hip adductor isolation move.
- Because it's a light, single-joint machine exercise, most people can train it 2 to 3 times a week without much recovery cost.
- Use it as an accessory after your main lower-body lifts rather than as a primary leg exercise.
Safety notes
- Adjust the pads to sit against the thighs, not the knee joint, before loading the machine.
- Keep the starting width within what feels comfortable in the groin and hip; stop if you feel joint pain rather than muscle fatigue.

Frequently asked questions
How many reps on the thigh adductor machine should I do?
2 to 3 sets of 12 to 20 reps at a resistance you can fully control works well.
What can I do instead of the thigh adductor machine?
Band hip adductions, pulling a resistance band inward with the leg, train the same inner-thigh muscles without a machine.
Thigh adductor vs thigh abductor machine, what's the difference?
The adductor machine trains the inner-thigh muscles that bring the legs together, while the abductor machine trains the muscles on the outside of the hip that spread the legs apart.
Why do I feel tightness in my groin after this exercise?
Mild tightness in the inner thigh and groin is expected after working the adductors directly; sharp or lasting pain is not, and means the starting width or resistance should come down.
