Hip Adductor Machine
The hip adductor machine is a seated exercise where you squeeze padded levers together with your inner thighs, moving the legs toward the midline against resistance. It trains the adductor group, including the adductor magnus, longus and brevis, which help stabilise the hips and contribute strongly to squats, lunges and deadlifts.

What muscles does the hip adductor machine work?
Primary movers
- Adductor magnus
- Adductor longus
- Adductor brevis
Assisting muscles
- Gracilis
- Pectineus
Hip adduction means bringing the thigh towards the midline of the body. The adductor group, on the inside of the thigh, performs this action and is a much larger muscle mass than most people realise.
The adductor magnus is one of the largest muscles in the lower body. As well as adduction, it is a powerful hip extender, which is why it works so hard at the bottom of a squat and during deadlifts.
Strong adductors help stabilise the knees and pelvis and reduce the risk of groin strains, which are common in sports that involve sprinting and changing direction.
The machine isolates adduction with full support, so it is an easy way to strengthen these muscles directly. Starting from a wider position puts them under more stretch, which increases the training stimulus.
How to do the hip adductor machine
Setup
- 1
Adjust the starting position so your legs are spread to a comfortable stretch, not a painful one.
- 2
Sit with your back against the pad and place the pads on the inside of your knees.
- 3
Hold the handles and place your feet on the footrests.
- 4
Brace your core and sit tall.
Execution
- 1
Squeeze your knees together, pulling the pads towards the centre.
- 2
Pause for a second when the pads meet and squeeze your inner thighs.
- 3
Return slowly to the starting position, controlling the stretch.
- 4
Stop just before the weight touches down to keep tension on the muscles.
- 5
Keep your back on the pad and avoid leaning forward.
- 6
Breathe steadily throughout the set.
Common hip adductor machine mistakes
Starting too wide
Setting the machine at your maximum stretch from the first rep, which can strain the groin, especially when the muscles are cold.
The fix: Begin with a moderate starting width and increase it gradually over several sessions as you get used to the stretch.
Letting the weight snap back
Releasing the pads quickly so the legs are pulled open under load. This loses tension and puts stress on the groin.
The fix: Control the return over two to three seconds.
Using momentum
Bouncing the legs together with fast reps, which reduces the work done by the adductors.
The fix: Move steadily and pause at the centre.
Lifting the hips off the seat
Shifting the hips or leaning forward to move more weight, which brings other muscles into the movement.
The fix: Keep your back on the pad and your hips planted.
How many sets and reps?
| Goal | Sets | Reps | Load | Rest |
|---|---|---|---|---|
| Hypertrophy | 3 | 12–15 | Moderate, 1–2 RIR | 60 s |
| Groin resilience | 2–3 | 12–15 | Light to moderate, slow return | 60 s |
| Strength | 3 | 8–12 | Heavy | 90 s |
Use the hip adductor machine after squats or lunges for two to three sets of 12 to 15. Athletes in sprinting and field sports can benefit from including it regularly to build groin resilience. Build the range of motion gradually, never forcing a deep stretch under heavy load.

Frequently asked questions
What muscles does the hip adductor machine work?
The adductor magnus, adductor longus and adductor brevis, along with the gracilis and pectineus. Together these muscles make up the inner thigh.
Is the hip adductor machine worth doing?
Yes. The adductors are a large muscle group that supports the hips and knees, contributes to squats and deadlifts and protects against groin strains. The machine is a simple way to train them directly.
Does the adductor machine help your squat?
It can. The adductor magnus is a key hip extender at the bottom of a squat. Stronger adductors can help you drive out of the hole and keep your knees stable.
Will the hip adductor machine slim my inner thighs?
No. Spot reduction is a myth. The machine strengthens and builds the inner thigh muscles. Fat loss depends on overall diet and activity.
How wide should I set the adductor machine?
Wide enough to feel a stretch in the inner thighs, but not so wide that it feels painful. Increase the range gradually over several weeks.
