Setup
- Stand with your feet wider than shoulder-width apart and hinge forward at the hips until your torso is nearly parallel to the floor.
- Hold a dumbbell in one hand and brace your free hand on the opposite knee for support.
- Press the back of your upper arm (triceps) firmly against the inside of your thigh on the same side.
- Let the dumbbell hang at full arm extension with your palm facing forward.
How to do it
- Exhale as you curl the weight toward your shoulder, keeping your upper arm pinned against your thigh to prevent any swinging.
- Squeeze your bicep forcefully at the top of the movement for a one-second pause.
- Inhale as you slowly lower the dumbbell back to the starting position over a 3-second count.
- Perform the desired number of repetitions on one arm before switching to the other.
Form checklist
- Keep your torso still; do not rock your body to help lift the weight.
- Ensure the elbow remains tucked against the inner thigh throughout the entire set.
- Achieve a full stretch at the bottom without locking out the elbow aggressively.
- Keep your wrist firm and avoid letting it 'flop' backward during the curl.
Pro tips
- At the top of the rep, rotate your wrist so your pinky finger points toward your shoulder to maximize bicep supination.
- Focus on the mind-muscle connection by imagining you are trying to touch your forearm to your bicep.
Make it harder
- Incorporate a 3-second pause at the peak of the contraction to increase time under tension.
- Use a 'fat grip' or wrap a towel around the handle to increase forearm and grip demand.
