Leg training with only dumbbells: what to pick, how to load it, how to progress

The legs are the strongest muscles in the body, and that is the problem dumbbells have to solve. A barbell squat or a leg press can load more than you could ever hold in your hands; with dumbbells, your grip, your shoulders and the heaviest pair on the rack all set a ceiling. A goblet squat stops getting harder once the dumbbell is too heavy to hold at your chest, and a two-dumbbell Romanian deadlift often ends because your hands give out before your hamstrings do.

What dumbbells do well is single-leg work. When one leg does the job, a pair that is light for a squat becomes hard for a split squat, so the ceiling moves back out of the way. Dumbbells also need no rack and no set-up, work anywhere on the floor, and make it easy to choose gentler versions such as a reverse lunge or a low step-up. The weak spots are the back of the knee and the inner thigh: there is no clean dumbbell version of a leg curl, and the adductors get their work from wide and sideways stances rather than a dedicated exercise.

This page is for sessions where dumbbells are the only tool, by choice, at home or on a crowded day. The leg exercises guide covers leg training as a whole, machines and barbells included, and how many sets each muscle needs a week; everything here uses a set of dumbbells and, now and then, a bench.

You need more than one pair. Two-leg hinges and squats take the heaviest dumbbells you can hold; split squats and lunges take a moderate pair; single-leg Romanian deadlifts and calf raises often start lighter still. Pick a starting weight for each movement by reps, not by the number on the handle: it is right when the set ends with good form and about two reps left. For the goblet squat you hold one dumbbell upright against your chest, cupping the top end in both hands, so a single heavy dumbbell can do the job of a pair.

• Grip goes first on heavy Romanian deadlifts. Lifting straps are a reasonable fix; so is switching to the single-leg version, which needs about half the weight.
• Dumbbells hanging at your sides keep the torso upright and suit lunges and step-ups. A single dumbbell at the chest is easier to balance for squats and split squats when you are new.
• At the light end, the step from one pair to the next is a big jump compared with the weight itself. The progression section below covers what to do when the next pair is too heavy.

Sort dumbbell leg exercises by job and a complete session assembles itself: one from each group covers the whole leg. Pages in the library are linked; the rest are described here.

• Squats, for the quads, glutes and inner thighs: the goblet squat, the sumo squat with one dumbbell hanging between wide feet, and the wall sit with a dumbbell resting on your thighs, for a hard hold without movement. Raising the heels on a small step makes the goblet squat more quad-heavy.
• Single-leg squats and lunges, for the quads and glutes: the Bulgarian split squat with the back foot on a bench, the reverse and walking lunge, the step-up onto a bench or box, and the lateral lunge, which stretches the inner thigh as you sit into one side.
• Hinges, for the hamstrings and glutes: the Romanian deadlift with a dumbbell in each hand, and the single-leg Romanian deadlift, which gives the hamstrings heavy work with a fraction of the weight.
• Glutes at the top of the range: the hip thrust with a dumbbell across the hips and the upper back on a bench, and the single-leg glute bridge on the floor.
• Calves: the calf raise, one leg at a time on a step, a dumbbell in the hand on the same side and the other hand on a wall.
• The hamstrings at the knee: a dumbbell leg curl, lying face down on a bench with a dumbbell held between the feet. It works but is awkward to load, so most people rely on the hinges above and keep it as a light finisher.

On both days the first exercise gets your hardest effort. If you own only one or two pairs, keep the heavier pair for the split squat and the Romanian deadlift, and use slow tempos and pauses to make the goblet squat and lunges hard enough.

Dumbbell leg training stalls in a predictable place: you finish every set at the top of the rep range, and the next pair is too heavy to reach the bottom of it. Before you move up, make the same weight harder. Use one of these at a time.

• More reps. Move from 8–10 to 12–15 before changing the weight; the legs respond well to the higher range.
• Slower lowering. Three or four seconds on the way down at the same weight makes most sets noticeably harder.
• A pause at the bottom. One or two seconds in the deepest position of a split squat or goblet squat removes the bounce.
• One-and-a-half reps. All the way down, halfway up, back down, then all the way up: that counts as one.
• A harder version. Two legs to one, a split squat to a Bulgarian split squat, a low step to a higher box.
• Less rest. Cutting rest from two minutes to one makes later sets harder, though it trains fatigue more than strength.

When the harder version reaches the top of its range, take the next pair and drop back to the bottom of the rep range. A simple log for each exercise makes this easy to see, and the training volume calculator totals your sets across the week.

• One pair for everything. The weight that suits a calf raise is far too light for a Romanian deadlift.
• Endless light goblet squats. If a set takes thirty reps to get hard, it is training endurance more than muscle; move to a single-leg version.
• No hinge. Squats and lunges leave the hamstrings undertrained; every leg day needs a Romanian deadlift in one form or the other.
• Rushing single-leg reps. Speed hides wobbles and short ranges; slow down and start with the weaker leg.
• Letting the grip end the set. If the hands fail first, use straps or the version that needs less weight.
• Pushing through knee pain. Effort in the muscles is expected; sharp or lingering pain in the knee or hip is a reason to stop and have it checked by a doctor or physiotherapist.

RPM's photos of the Al Manhal floor show a dumbbell rack and kettlebells in the functional training area, flat benches for split squats, step-ups and hip thrusts, and soft plyo boxes that suit step-ups. Adjustable benches are not in the photos, so ask about them on your free tour. When you want more load than dumbbells allow, the leg press and the squat racks are on the same floor, and a coach in a personal training session can fit your dumbbell days into a full plan.
