Clam

Clam trains the gluteus medius and other hip abductors by moving the thigh away from the body's midline without rotating the pelvis.

Set up for Clam

Prepare the training area

Use a level, non-slip surface and clear enough room for the complete movement.
Place any required mat, bench, or stable hand support before taking the starting position.

Position yourself for Clam

Align the working hip with the resistance for Clam, stabilize the pelvis, and arrange the support leg or torso so it cannot sway.
Keep both hip bones facing forward and use support that prevents the torso from leaning away from the working leg.

Choose and verify the starting level

Choose the easiest Clam variation that preserves the required body line and full controlled range; use elevation, support, or assistance as needed.
Perform one slow rehearsal repetition and change the setup if the equipment shifts, the range causes pain, or the target position cannot be maintained.

How to perform Clam

Follow the sequence in order, paying attention to the starting position, movement path, and finish described in each step.

Set the working hip for Clam with the pelvis square and the support leg or torso stable.
Bend the hips and knees, stack the feet and hips, and keep the heels together as the top knee begins to open.
Move the thigh away from the midline without turning the toes up or leaning the trunk in the opposite direction.
Pause when the side glute is shortened and before the pelvis begins to rotate.
Return slowly until tension is reduced but not lost. Repeat without changing the established position.

Common Clam mistakes

These are the form changes most likely to move work away from the target muscles or make the repetition harder to control.

Pelvis rotating

Keep both hip bones facing forward so the thigh moves independently from the trunk.

Leaning away

Use support and reduce resistance if the torso must tilt to move the leg.

Toe turning upward

Keep the kneecap facing forward or slightly down to avoid replacing abduction with hip rotation.

Snapping back

Return slowly and prevent the cable, band, or machine from pulling the leg inward.

When to modify or choose another exercise

Reduce the resistance, range, lever length, or balance demand if Clam cannot be completed without compensation.
Stop when the exercise produces sharp, catching, radiating, or increasing joint pain rather than the expected muscular effort.
Choose a stable supported alternative when fatigue, balance, equipment fit, or a current medical restriction prevents repeatable technique.

Programming guide

How to use Clam in a training program

Use Clam as accessory work after larger compound exercises, or earlier only when its target action is the session's priority.

Where it fits in a session

Use Clam after larger compound movements, or earlier only when its target action is the workout's main priority.

How often to use it

Use one to three times per week and count the work alongside compound exercises that train the same muscles.

Starting rep ranges by goal

Goal	Sets	Reps or time	Rest	Effort and execution
Strength accessory	2–4	6–10	75–150 sec	Leave 2–3 controlled reps in reserve
Muscle growth	2–4	10–20	60–120 sec	Usually 1–3 clean reps in reserve
Local endurance	2–3	15–25	45–90 sec	Stop before range or joint position changes

How to progress it

Add controlled repetitions within the selected range before increasing resistance. For unilateral work, progress each side according to the weaker technically sound performance.

Pairing and sequencing

Superset with a non-competing accessory when both exercises can keep their intended joint paths.
Do not add isolation volume without counting the work already received from compound lifts.

Coach's notes

Program 2–4 sets of 8–15 controlled repetitions; 12–20 repetitions can also suit lighter isolation and rotator-cuff work.
Rest 45–90 seconds, extending the interval if fatigue changes joint position or the intended muscle action.
Add repetitions before load and count these sets toward the weekly volume already supplied by compound exercises.
