Do I need a step for single-leg calf raises?

No. On flat ground the exercise trains the top half of the ankle's range, which is enough for beginners and a common starting point in calf and Achilles programs. Move to a step once the floor version feels easy and you want the stretched range too, unless dropping the heel aggravates pain at the back of the heel.

Which hand should hold the dumbbell?

Holding it on the same side as the working leg, as shown, keeps the load running straight down through the standing foot. Holding it in the opposite hand also works, so pick one and use it on both legs so your numbers stay comparable.

Is the number of single-leg calf raises I can do a good measure of calf strength?

Not really. In a study of healthy young adults, the number of bodyweight single-leg heel raises done to failure did not track with maximal calf strength measured on a dynamometer, and instead reflected how quickly the calves fatigued. Treat your rep count as an endurance marker and compare the two legs against each other.

How many sets and reps should I do?

Two to four sets of 10 to 20 controlled reps per leg suits most people, with the last few reps of each set feeling hard. Add weight only when you can complete every rep with a pause at the top and without losing balance.

Dumbbell Single-Leg Calf Raise

What Is the Dumbbell Single-Leg Calf Raise?

Dumbbell Single-Leg Calf Raise is an isolation exercise that primarily targets the lower legs, working the gastrocnemius and soleus, and also engages the peroneal muscles on the outside of the shin and the hip muscles that keep you balanced on one foot. It is a beginner-level movement done standing on one foot on flat ground, with a dumbbell held at your side and the other foot hooked behind the standing ankle.

Training one leg at a time puts your whole body weight plus the dumbbell through a single calf, so it takes far less external load to challenge the muscle than a two-footed raise, and any strength difference between your left and right side becomes obvious. That makes it a practical calf exercise for home or hotel workouts with a single dumbbell, and a staple of strength work for runners and of Achilles tendon rehab programs, where it usually follows two-footed raises.

With the standing knee straight, the gastrocnemius, which crosses both the knee and the ankle, does a large share of the work alongside the soleus. Bending the knee, as in the Bodyweight Single-Leg Bent-Knee Calf Raise, shifts more of the load to the soleus. Because the heel only returns to the floor here, this version trains the top half of the ankle's range and never reaches the stretched position below the toes. An eight-week study of young women training calf raises on a leg press found that partial reps in the stretched half of the range grew the gastrocnemius more than top-half reps, so once the floor version feels easy, doing it on a step is the natural next move for calf size.

The flat-floor version suits beginners, people building balance and ankle control, and anyone who wants to keep the ankle out of a deep stretch. If balancing on one foot with a weight is too hard, build up with the two-footed Bodyweight Calf Raise or Dumbbell Standing Calf Raise first, then do single-leg raises without the dumbbell and with a hand on a wall.

Instructions

Stand tall on flat ground and hold a dumbbell at your side in the hand on the same side as your working leg, palm facing your thigh.
Shift your weight onto the working foot, bend the other knee and hook that foot behind the standing ankle.
Keep the standing knee straight and let your free arm hang relaxed, or rest its fingertips lightly on a wall for balance.
Spread your weight across the ball of the foot, with steady pressure through the big toe.
Push through the ball of the foot to raise your heel as high as you can, rising straight up without leaning forward.
Pause briefly at the top with the ankle stacked over the ball of the foot, not rolled onto its outer edge.
Lower the heel under control until it touches the floor lightly, then start the next rep without bouncing.
Complete your reps, switch the dumbbell to the other hand and repeat on the other leg.

Common Mistakes

Bouncing through reps
Dropping onto the heel and springing straight back up lets the Achilles tendon do the work and takes tension off the calf.
Stopping short of the top
Without a step, the top of the raise is where this version does its work, so cutting it short leaves little range to train.
Rolling onto the outer edge of the foot
Letting the ankle tip outward at the top shifts load onto the little toes and stresses the outside of the ankle.
Leaning forward or bending the standing knee
Pitching the hips forward or softening the knee lets body lean replace ankle movement and shortens the raise.
Using a dumbbell too heavy to balance
A weight that pulls you off balance turns each rep into a wobble, so add reps or slow the tempo before adding load.

Injuries

Dumbbell Single-Leg Calf Raise is a low risk exercise when performed with proper technique. The loads are modest and the range is short, so problems usually come from bouncing through reps, jumping to a much heavier dumbbell, or starting cold. The Achilles tendon and the calf muscle take the most strain, and the outer ankle is exposed if the foot rolls onto its outside edge or you lose balance at the top.

Warm up with a set of two-footed raises, move at a steady tempo with a brief pause at the top, and keep pressure through the big toe so the ankle stays stacked over the ball of the foot. Rest your free hand on a wall whenever balance limits the set, and if you start to tip, put the other foot down rather than fighting to stay up. Because the heel never drops below the toes, the floor version keeps the ankle out of a deep stretch, which is why physical therapists often use floor-level raises for pain where the Achilles attaches to the heel bone.

To regress, return to the two-footed Bodyweight Calf Raise or do single-leg raises without the dumbbell. To progress, use a heavier dumbbell, slow the lowering phase, or perform the raise on a step so the heel can drop below the toes.

Stop the set if you feel sharp pain in the Achilles tendon or calf, a sudden pull or pop in the calf, or the ankle giving way. Achilles pain that is worse the next morning is a sign to reduce the load or volume and get it checked if it persists.
