The side plank hip adduction is a bodyweight strength exercise that targets the inner-thigh adductors (adductor brevis, longus, magnus, and pectineus), gluteus medius, and obliques simultaneously. Supported on one forearm and the top foot, you lift the lower leg upward toward the upper leg against gravity, building hip stability and lateral core control in a single movement.
How to do the Side Plank Hip Adduction
- 1Lie on your side and prop yourself up on your forearm, stacking your elbow directly beneath your shoulder. Place your top foot flat on the floor slightly in front of your hip so your body is supported by your forearm and the side of your top foot.
- 2Extend your bottom leg out straight below the top leg, parallel to the floor. This is your starting position.
- 3Brace your core and engage your obliques to keep your hips lifted and your body in a straight line from head to heel.
- 4Raise your bottom leg upward toward your top leg in a controlled arc, driving the movement with your inner-thigh adductors.
- 5Lift until your bottom leg is as close to the top leg as your range of motion allows, pausing briefly at the top to maximize muscle tension.
- 6Lower the bottom leg back down slowly under control until it nearly returns to the starting position without touching the floor.
- 7Complete all reps on one side, then switch sides and repeat.
Form tips
- Keep your hips stacked vertically throughout — do not let them rotate forward or backward as you lift the bottom leg.
- Initiate the lift from your inner thigh, not from momentum or a hip hike. Think of squeezing the thighs together.
- Maintain a rigid plank through your torso; if your hips sag during the lift, reduce your range of motion or lower the rep count.
- Move deliberately — a 2-second lift and 3-second lower maximizes time under tension in the adductors and the stabilizing obliques.
- Keep your bottom foot flexed with toes pointing forward rather than rotated outward, which keeps the adductors fully engaged rather than shifting work to the hip flexors.
Common mistakes
- Letting the hips drop or rotate during the leg lift, which offloads the adductors and obliques and places strain on the lower back.
- Using momentum to swing the bottom leg upward rather than a controlled muscular contraction, reducing adductor activation and risking hip joint strain.
- Pointing the bottom foot toward the ceiling instead of straight ahead, which externally rotates the hip and recruits hip flexors instead of the target adductors.
- Losing the side-plank brace and letting the torso collapse downward, turning a stability-strength exercise into a passive stretch with no training benefit.
- Resting the bottom leg on the floor between reps, which removes tension from the adductors and cuts total work for the set.
Frequently asked questions
What muscles does the side plank hip adduction work?
The primary muscles are the inner-thigh adductors (adductor brevis, longus, magnus, and pectineus), the gluteus medius, and the obliques. The gracilis and tensor fasciae latae assist as synergists.
Is the side plank hip adduction suitable for beginners?
Yes, with a modification. Beginners can rest the top knee on the floor to reduce the side-plank balance demand, then progress to the full position as core stability improves.
How many sets and reps should I do for the side plank hip adduction?
For strength and stability, 2–3 sets of 10–15 controlled reps per side is a solid starting range. Prioritize slow, deliberate movement over rep count.
What is the difference between side plank hip adduction and side plank hip abduction?
In hip adduction the bottom leg lifts toward the top leg, working the inner-thigh adductors. In hip abduction the top leg lifts away from the body, targeting the outer glute and hip. Both begin from a side plank but train opposite muscle groups.
Where should I feel the side plank hip adduction?
You should feel the effort along your inner thigh as the bottom leg rises, in the outer hip of the supporting side from the gluteus medius holding your plank, and in your obliques bracing the lateral core throughout.
