The medicine ball single leg deadlift is a unilateral hip-hinge exercise that challenges the hamstrings, glutes, and lower back while demanding significant balance and core stability. Performed on one leg while holding a medicine ball, it builds posterior chain strength and corrects left-to-right imbalances simultaneously.
How to do the Medicine Ball Single Leg Deadlift
- 1Stand upright holding a medicine ball with both hands in front of your hips, feet hip-width apart.
- 2Shift your weight onto your right foot and soften the knee slightly — do not lock it out.
- 3Hinge forward at the hips, pushing your hips back as you lower the medicine ball toward the floor.
- 4Simultaneously extend your left leg straight behind you, keeping your hips square to the ground.
- 5Lower until your torso and left leg are roughly parallel to the floor, or until you feel a strong stretch in the right hamstring.
- 6Keep your back flat, core braced, and the medicine ball close to your standing leg throughout the descent.
- 7Drive through the right heel to extend the hip and return to the upright starting position, bringing the left leg forward.
- 8Complete all reps on one side before switching legs.
Form tips
- Keep your hips square — resist the urge to rotate the lifted hip toward the ceiling as you hinge.
- Fix your gaze on a point about one metre ahead on the floor to help maintain a neutral spine and steady balance.
- Think about pushing your free foot back and up rather than just lifting it — this activates the glute and keeps the movement hip-driven.
- Control the descent over 2–3 seconds; a slow eccentric builds more hamstring strength and makes balance easier to maintain.
- If balance is a limiting factor, lightly touch the toes of the free foot to the floor at the bottom before progressing to a fully suspended rep.
Common mistakes
- Rounding the lower back: Losing a neutral spine shifts stress from the hamstrings and glutes onto the lumbar vertebrae, increasing injury risk. Brace the core and keep the chest proud throughout.
- Rotating the hip open: Letting the free-leg hip rise higher than the standing hip twists the pelvis and reduces glute engagement. Actively pull the free hip down to stay square.
- Bending the standing knee excessively: Turning the movement into a single-leg squat removes the hip-hinge stimulus and shifts load away from the posterior chain. Keep a slight, fixed bend — not a deep squat.
- Letting the medicine ball drift away from the body: Holding the ball far from the standing leg creates a long moment arm that strains the lower back. Keep it close and track it along the shin.
- Rushing through reps: Moving too quickly relies on momentum rather than controlled muscle contraction, undermining stability and strength gains. Slow down, especially on the way down.
Frequently asked questions
What muscles does the medicine ball single leg deadlift work?
The exercise primarily works the hamstrings and glutes of the standing leg through the hip-hinge pattern. The lower back (erector spinae) works isometrically to maintain a flat spine, while the core and hip stabilisers on both sides engage heavily to control balance throughout the movement.
How is the medicine ball single leg deadlift different from a dumbbell or barbell single leg deadlift?
Holding a single medicine ball with both hands in front of the body keeps the load centred, which can make balance slightly easier to manage than holding a dumbbell in one hand. The bilateral grip also reduces grip-fatigue as a limiting factor, letting you focus on the hip hinge and posterior chain.
How heavy should the medicine ball be?
Choose a weight that lets you complete all reps with a flat back and controlled balance. For most people, a 4–8 kg (8–18 lb) ball is a good starting range. Prioritise form and stability over load — the single-leg stance already makes this exercise challenging at modest weights.
Can beginners do the medicine ball single leg deadlift?
Yes, with modifications. Beginners should first master the basic hip-hinge pattern and two-legged deadlift before progressing to a single-leg version. Start by lightly touching the free foot to the floor at the bottom of each rep for added stability, then progress to fully lifting the leg once balance improves.
How many sets and reps should I do?
For strength and balance, 3–4 sets of 6–10 reps per leg works well. For endurance or warm-up purposes, 2–3 sets of 12–15 reps with a lighter ball is effective. Rest 60–90 seconds between sets to allow the stabilising muscles to recover.
