The dumbbell bench one leg squat is a single-leg strength exercise that targets the thighs — the quadriceps and glutes — while the bench behind you sets a consistent depth. Holding dumbbells for load, you squat down on one leg until you touch the bench, then drive back up, building leg strength, balance, and side-to-side symmetry.
How to do the Dumbbell Bench One Leg Squat
- 1Stand facing away from a flat bench, a few inches in front of it, holding a dumbbell in each hand at your sides.
- 2Lift one foot slightly off the floor and balance on your working leg, keeping your chest up and core braced.
- 3Push your hips back and bend your standing knee, lowering under control toward the bench.
- 4Sit back until your glutes lightly touch the bench, keeping your weight in the heel of the working leg.
- 5Pause briefly without resting your full weight on the bench, keeping tension in the working leg.
- 6Drive through your foot to stand back up, fully extending the hip and knee.
- 7Complete all reps on one leg, then switch and repeat on the other side.
- 8Set the dumbbells down with control when finished.
Form tips
- Keep your standing knee tracking over your toes rather than caving inward as you lower and rise.
- Set the bench height so your thigh reaches roughly parallel at the bottom — a higher bench is an easier starting point.
- Touch the bench lightly each rep rather than dropping onto it, so the working leg keeps the tension.
- Start with light dumbbells until your balance is solid, then add load gradually.
- Keep your torso tall and your core braced to stay balanced through the full range.
Common mistakes
- Plopping down and resting fully on the bench between reps, which kills muscular tension and turns it into a rest stop instead of a controlled squat.
- Letting the standing knee collapse inward, which stresses the knee joint and weakens the drive out of the bottom.
- Leaning the torso too far forward, which shifts load off the quads and can strain the lower back.
- Rushing the descent and bouncing off the bench, removing control and increasing injury risk.
- Training one leg noticeably harder than the other, which builds the side-to-side imbalance this exercise is meant to fix.
Frequently asked questions
What muscles does the dumbbell bench one leg squat work?
It mainly works the thighs — the quadriceps and glutes of the working leg — while your core and standing-leg stabilizers fire to keep you balanced through each rep.
Is the dumbbell bench one leg squat good for beginners?
Yes. The bench gives you a depth target and a safety cushion, so it's a good way to learn single-leg strength. Start with no weight or very light dumbbells until your balance is solid.
How high should the bench be?
A standard flat bench works for most lifters, bringing your thigh to about parallel at the bottom. Use a higher box or bench to make it easier, or a lower one to increase the range of motion.
How many sets and reps should I do?
For leg strength and balance, 3 sets of 8 to 12 reps per leg is a sensible default. Train both legs evenly and increase the dumbbell weight once you can finish all reps with clean form.
What's a good alternative to the dumbbell bench one leg squat?
Bulgarian split squats and dumbbell step-ups are close single-leg alternatives that also load the quads and glutes while challenging balance.
