Dumbbell Seated Single-Leg Calf Raise
What Is the Dumbbell Seated Single-Leg Calf Raise?
Dumbbell Seated Single-Leg Calf Raise is an isolation exercise that primarily targets the lower legs, especially the soleus, and also engages the gastrocnemius. It is a beginner-level movement in which you sit on the end of a bench with the ball of one foot on a step, rest a dumbbell on that thigh just above the knee and raise and lower the heel through a full range.
The soleus is the deep, flat calf muscle that lies under the gastrocnemius and crosses only the ankle. The gastrocnemius crosses the knee as well, so bending the knee to about 90 degrees shortens it and leaves less of it able to help, which shifts more of the work onto the soleus. That is the reason to train calves seated as well as standing. The soleus carries much of the load at the ankle when you walk and run and works hard to control the Achilles tendon, so runners, field and court athletes and anyone building lower-leg endurance tend to include some bent-knee calf work.
Working one leg at a time has two practical benefits. Each calf has to lift the full load on its own, so a weaker side cannot hide behind the stronger one, and a single dumbbell gives a meaningful load on one leg that would feel light split across two. It is a good choice when there is no seated calf machine available. The two-leg Dumbbell Seated Calf Raise lets you use more total weight, and the Machine Single-Leg Seated Calf Raise does the same job with a padded lever instead of a dumbbell.
The main limit of the dumbbell version is how much weight you can comfortably balance on one knee, so it suits higher reps, slow lowering and pauses at the top and bottom rather than very heavy loads. If you are new to calf training, start with the Bodyweight Single-Leg Bent-Knee Calf Raise or with no dumbbell at all, then add weight once you can control a full stretch and a full rise for every rep. Keeping your attention on the heel moving straight up and down helps keep the work in the calf instead of in your arms pushing the dumbbell.

Instructions
- Place a step platform in front of the end of a flat bench and sit upright on the bench edge.
- Put the ball of your working foot on the edge of the step with the heel hanging off, so the knee is bent to about 90 degrees and directly above the foot.
- Rest the other foot on the floor for balance.
- Stand a dumbbell on end on the working thigh just above the knee, with a folded towel underneath if needed, and hold it steady with your hand.
- Let the heel sink slowly below the level of the step until you feel a stretch in the calf, and pause for a moment.
- Push through the ball of your foot and big toe to raise the heel as high as you can, keeping the knee still and the ankle from rolling outward.
- Hold the top position for a moment, then lower the heel slowly back into the stretch without bouncing.
- Complete all reps on one leg, then switch the dumbbell and foot to the other side.
Common Mistakes
Bouncing at the bottom
Dropping fast into the stretch and rebounding out of it lets the Achilles tendon do the work and puts the tendon under sudden load, so pause briefly at the bottom instead.
Cutting the range short
Stopping halfway up or never letting the heel sink below the step skips the parts of the rep where the calf works hardest.
Using a dumbbell that is too heavy
A weight you cannot hold steady on one knee turns the set into short, jerky reps and usually ends with the dumbbell rolling off the thigh.
Pushing the dumbbell up with the arms
Your hands should only keep the dumbbell in place, because pressing it upward takes the load off the calf.
Rolling onto the outer edge of the foot
Letting the ankle tip outward as the heel rises shifts the load to the outside of the foot, so drive straight up through the ball of the foot and big toe.
Rushing the reps
Fast reps with no pause at the top or bottom turn the set into momentum, so lift and lower under control and hold the top for a moment.
Injuries
Dumbbell Seated Single-Leg Calf Raise is a low risk exercise when performed with proper technique. Sitting takes balance and the lower back out of the movement, and the load is limited to what you can hold on one knee, so most problems come from bouncing, from adding range or weight too quickly, or from a poor setup.
The usual strain points are the Achilles tendon and the calf muscle itself, especially when the heel drops fast into the bottom and rebounds out of it. Lower under control, pause briefly in the stretch and build depth gradually over a few sessions. Calves often cramp the first few times they are trained hard on one leg, so start with lighter weight and fewer sets. Place the dumbbell on the lower thigh just above the kneecap, with a folded towel underneath if it presses uncomfortably, and make sure the step is stable and your foot is set firmly on it so it cannot slide off.
To make it easier, use both legs as in the Dumbbell Seated Calf Raise, use a lighter dumbbell or keep the heel from dropping below the step. To progress, add weight, slow the lowering phase or hold the top position for a two-second count, or move to the Machine Single-Leg Seated Calf Raise when you need more load than one knee can hold.
Stop if you feel sharp pain in the Achilles tendon or the back of the heel, pain that is still worse the next morning, or a sudden pop or pulling sensation in the calf. Pain where the tendon meets the heel bone is often aggravated by deep heel drops, so keep the heel level with the step and get it checked by a clinician before training through it.

Frequently Asked Questions
- Q: Can seated calf raises replace standing calf raises?
No, they work best together. In a 12-week study of untrained adults who trained one leg on a seated calf-raise machine and the other on a standing one, the soleus grew by a similar amount in both legs, but the gastrocnemius grew only in the standing leg. Pair this exercise with a straight-knee raise such as the Dumbbell Single-Leg Calf Raise.
- Q: Why do this one leg at a time instead of with both legs?
Working one leg lets a single dumbbell load each calf more heavily and stops a stronger side from doing more than its share. If one calf is clearly weaker or smaller, start each set with that side and match its reps on the other leg.
- Q: How do I keep the dumbbell from hurting my knee?
Rest the end of the dumbbell on the lower thigh just above the kneecap rather than on the kneecap itself, and fold a towel or use a pad underneath it. Hold it steady with your hands without pressing down or lifting it.
- Q: How many reps should I do?
Most people do well with 12 to 20 controlled reps per leg for 2 to 4 sets, with a short pause at the top and bottom of each rep. If you can do more than 20 with full range and good control, add weight or slow the lowering phase.
- Q: What if I do not have a step?
Any stable, raised surface works, such as a weight plate or a thick book, as long as the heel can sink below the ball of the foot. Without one, you can do the raise with the foot flat on the floor, but you lose the stretch at the bottom of each rep.
