## Description

The Dumbbell Single Leg Hip Thrust is a unilateral glute builder performed with your upper back supported on a flat bench, one foot planted on the floor, and a dumbbell held against the hip of the working leg. The non-working leg stays lifted with the knee bent, which removes any help from that side and forces the planted leg's glutes to do the lifting on their own. It is essentially a single-leg version of the classic barbell hip thrust, scaled down in load but up in balance and control demands.

This exercise is useful for almost anyone training at home or in a busy gym, because a single dumbbell and one bench are all you need. It works especially well for lifters who feel back squats mostly in their thighs, for runners and cyclists who want stronger hip extension one side at a time, and for anyone addressing a left-right strength difference. Since each glute has to produce the force alone, weaker sides get exposed and can be brought up evenly.

The main work is done by the glutes, with the hamstrings assisting on the drive and the core and lower back working to keep your ribcage and pelvis level throughout. Because you are balancing on one leg, the stabilizing role of the hip of the working side is much greater than in the two-legged version, and the raised leg's hip flexors work isometrically to hold that knee up.

Setup matters a lot here. Position the bench so it supports your upper back at the bottom of the shoulder blades, keep the dumbbell centered over the working hip so it does not roll toward the free side, and place your planted foot far enough forward that your shin is roughly vertical at the top. A foot too close to the bench turns the movement into a knee-dominant push, while a foot too far away shifts stress toward the hamstrings and lower back.

To perform it well, drive through the heel and mid-foot of the planted leg and push your hips up until your torso and raised thigh form a straight line, squeezing the working glute hard at the top. Lower with control until your hips are just above the floor and repeat. Keep your hips square to the ceiling the entire time; letting the free-side hip sag or rotate is the most common fault.

Start with a light dumbbell or even bodyweight until you can hold a level, stable pelvis for all repetitions. Because the load sits directly on the hip and the movement is short-range and joint-friendly, this is one of the safer ways to load heavy single-leg hip extension, but avoid bouncing out of the bottom and stop the set if your lower back starts arching to finish reps.

## Instructions

1. Sit on the floor with a flat bench behind you and rest a dumbbell within reach. Lean back so the edge of the bench supports your upper back across the bottom of your shoulder blades.
2. Roll the dumbbell onto the crease of your working hip and hold it in place with both hands. Bend that leg and plant the foot flat on the floor about a foot in front of your hip.
3. Lift your non-working leg off the floor and bend the knee, keeping the thigh roughly in line with the working thigh so your hips stay square.
4. Brace your core and tuck your chin slightly so your neck stays neutral and your ribs stay down over your pelvis.
5. Drive through the heel and mid-foot of the planted leg and push your hips toward the ceiling.
6. Finish with your torso and raised thigh forming a straight, level line, and squeeze the working glute hard at the top for a brief pause.
7. Lower your hips under control until they hover just above the floor, keeping tension in the glute rather than settling onto the ground.
8. Exhale as you drive up, inhale as you lower, and keep breathing steadily through the set.
9. Complete all reps on one side, then set the dumbbell down, switch legs, and repeat on the other side with the same technique.

## Tips & Tricks

- If the dumbbell digs into your hip or slides around, place a folded towel or pad between the weight and your hip bone and keep both hands on it for the whole set.
- A hip that tilts or rotates toward the raised leg usually means the weight is too heavy or the free leg is drifting. Lighten the load and consciously keep both hip bones pointing at the ceiling.
- If your lower back arches at the top, you are overextending instead of finishing with the glute. Stop at the point where your torso and raised thigh are level rather than pushing your hips higher.
- Keep the weight in the heel and mid-foot of the planted leg; pushing through the toes shifts effort to the thigh muscles and away from the glutes.
- Foot placement controls the feel: move the planted foot slightly further forward if you feel it mostly in the hamstrings, slightly closer if your knees take over.
- The raised knee tends to drop as you fatigue, which opens the hip and lets the pelvis rotate. Actively hold that knee up for the entire set.
- Do not bounce off the bottom. A brief pause with the hips just above the floor keeps the glutes loaded and protects the lower back.
- If balancing is the limiting factor, hold the bench frame lightly with one hand on your non-working side until your stability improves, then go hands-on-weight only.
- Match reps side to side, starting with your weaker leg, so one side never sets the standard for the other.

## Frequently Asked Questions

### Which muscles does the Dumbbell Single Leg Hip Thrust work?

The glutes, especially the gluteus maximus of the planted leg, do most of the work, with the hamstrings assisting the drive. Your core and lower back stabilize the pelvis, and the raised leg's hip flexors hold that knee up isometrically.

### Is the Dumbbell Single Leg Hip Thrust suitable for beginners?

Yes, as long as you start with bodyweight or a very light dumbbell. The main challenge is keeping the hips level while balancing on one leg, so master that with no weight before adding load.

### Where exactly should I place the dumbbell during the Dumbbell Single Leg Hip Thrust?

Rest it on the crease of the working hip, directly over the thigh bone, and hold it there with both hands. Keeping it centered over that hip stops it from rolling toward the free side and pulling your pelvis out of position.

### How far from the bench should my planted foot be?

Far enough that your shin is close to vertical when your hips reach the top. A foot tucked too close to the bench makes the push knee-dominant, while a foot too far forward turns it into a hamstring and lower-back movement.

### Why do my hamstrings cramp during the Dumbbell Single Leg Hip Thrust?

That usually means your foot is placed too far forward or your hips are not reaching full extension, so the hamstrings are compensating for the glutes. Bring the foot slightly closer, squeeze the glute deliberately at the top, and reduce the weight if needed.

### How high should I lift my hips at the top?

Until your torso and the thigh of your raised leg form a straight, level line, with a strong glute squeeze. Pushing beyond that point arches the lower back without adding glute work.

### What can I use instead of a dumbbell for this exercise?

A weight plate, kettlebell, sandbag, or a resistance band anchored over the working hip all work well. You can also perform it with just bodyweight, which is already challenging for many people in the single-leg version.

### Should my raised leg be straight or bent?

Bend the knee and keep the thigh roughly in line with the working thigh, as this keeps your hips square and makes the pelvis easier to control. A straight raised leg lengthens the lever and tends to pull your torso into rotation.

### How is the Dumbbell Single Leg Hip Thrust different from a two-leg hip thrust?

Each side works completely on its own, so you cannot push harder with your stronger leg, and the balance demand on the planted hip is much higher. The load is lighter, but the glute and stabilizer challenge per side is greater.

### Is the Dumbbell Single Leg Hip Thrust safe for my lower back?

For most people it is a lower-back-friendly way to train hip extension because the range is short and the load sits on the hip. Keep your ribs down, avoid overextending at the top, and use a weight you can lift without your pelvis tilting.
