What muscles does the single-leg standing calf raise work?

The primary muscle is the gastrocnemius, the two-headed muscle that gives the calf its rounded appearance. The soleus and ankle stabilisers work as secondary contributors, supporting plantarflexion and controlling balance throughout the movement.

How many sets and reps should I do for calf hypertrophy?

The calves respond well to moderate-to-high rep ranges — 3 to 4 sets of 10 to 20 reps per leg is a practical starting point for hypertrophy. Prioritise a full range of motion and a controlled tempo over simply accumulating reps.

Do I need a dumbbell, or is bodyweight sufficient?

Bodyweight alone is sufficient when you are establishing technique and building baseline strength. Once you can complete 15 or more controlled reps per leg with ease, adding a dumbbell in the free hand provides the progressive overload needed to continue driving adaptation.

How does this compare to the seated calf raise?

The standing position keeps the knee extended, which places greater demand on the gastrocnemius. The seated calf raise flexes the knee, shifting emphasis toward the soleus. Combining both exercises in a programme trains the full calf complex more completely than either movement alone.

Is this exercise suitable if I have a history of Achilles discomfort?

The deep stretch involved in this movement places significant load through the Achilles tendon, so if you have any history of tendon issues you should consult a qualified professional before including it in your programme.

Single-Leg Standing Calf Raise

Lower isolationFoundationalStepDumbbell (optional)

The single-leg standing calf raise is an isolation movement that trains the plantarflexors through a full range of motion, with one leg at a time to address side-to-side strength and size discrepancies. Performed on a step with the ball of the foot at the edge, it allows the heel to drop into a deep stretch before pressing to peak contraction — a range rarely achieved in bilateral or flat-floor variations. It suits beginners building foundational lower-leg strength through to athletes seeking unilateral calf development and improved ankle resilience.

How to do it

Stand on one foot on a step, ball of the foot on the edge, heel hanging off. Hold a support with one hand. Optionally hold a dumbbell in the other. Drop the heel into full stretch. Press up to peak contraction. Pause; lower under control.

Why train it

Training one leg at a time ensures each calf works independently, preventing the stronger side from compensating and helping to equalise left-to-right muscle development.
The hanging-heel position on a step creates a full eccentric stretch of the gastrocnemius that flat-floor raises cannot replicate, driving greater hypertrophic stimulus across the full muscle belly.
The single-leg stance demands continuous work from the ankle stabilisers, reinforcing the joint control that underpins running, jumping, and change-of-direction tasks.
An optional dumbbell in the free hand provides straightforward progressive overload without specialist equipment, making the exercise accessible across most training environments.

Common mistakes

Bouncing out of the bottom position — pause briefly in the stretched position and initiate each rep with a deliberate muscular contraction rather than elastic rebound.
Rising onto the toes instead of pressing through the ball of the foot — keep the foot correctly positioned on the step edge throughout so force travels efficiently through the intended joint.
Rushing the descent — lower the heel slowly and under control to maximise time under tension and protect the Achilles tendon from abrupt loading.
Gripping the support for balance assistance rather than light stabilisation — use the hand contact only to prevent swaying, keeping the working leg responsible for all the effort.
