- Compound
- Rep-based

Setup
- Stand approximately two feet in front of a low box or step, holding a dumbbell in each hand at your sides.
- Place the top of your rear foot on the box, ensuring your front foot is positioned far enough forward to allow a deep squat.
- Engage your core, pull your shoulders back, and shift your weight primarily onto the front leg.
How to do it
- Inhale and lower your hips by bending at the front knee and hip, maintaining a slight forward torso lean.
- Continue the descent until your front thigh is at least parallel to the floor, keeping your front knee aligned with your toes.
- Exhale and drive through the mid-foot of your front leg to return to the starting position.
- Perform the movement with a controlled 3-second eccentric (lowering) phase and a 1-second concentric (rising) phase.
Form checklist
- Keep the front heel firmly planted on the ground at all times.
- Avoid letting the front knee cave inward; keep it tracking over your toes.
- Maintain a neutral spine and avoid excessive arching in the lower back.
- Ensure the rear leg is used only for balance, not for pushing upward.
Pro tips
- Think of the rear leg as a 'kickstand'—80-90% of your weight should remain on the front leg throughout the set.
- To maximize glute engagement, hinge slightly more at the hips while keeping your chest up.
Make it harder
- Add a 2-second pause at the bottom of each rep to increase time under tension.
- Hold a single dumbbell in the hand opposite to the working leg (contralateral) to increase core and hip stabilizer demands.
