Running the calf raise one leg at a time inside the Smith machine gets you unilateral loading well past what a hand-held dumbbell allows, because the fixed bar handles the balance for you. Set the safety stops before your first rep; on single-leg work a calf can fail abruptly mid-set.

How to do the Single Leg Smith Machine Calf Raise

  1. Position yourself on the floor under the smith machine bar, facing away from the machine.
  2. Place the balls of your feet on a raised surface, such as a weight plate or block.
  3. Position the smith machine bar across your lower legs, just above your ankles.
  4. Hold onto the bar with your hands for stability.
  5. Raise your heels off the ground by extending your ankles, lifting your body up.
  6. Pause at the top of the movement, then slowly lower your heels back down to the starting position.
  7. Repeat for the desired number of repetitions.

Tip: Count two seconds up, hold one at the top and take three seconds down.

Muscles worked

Primary

Calves · Legs

Standing raises target the gastrocnemius while seated raises target the deeper soleus; either way you should feel a hard cramp-like squeeze at the top and a strong stretch at the bottom.

Secondary

  • Hamstrings — The hamstrings only stabilize here — it is the gastrocnemius that shares the knee-crossing role, so straight legs keep it loaded while bent knees hand the work to the soleus.
  • Glutes

Common mistakes

  • Bouncing out of the bottom — the Achilles tendon does the work if you rebound; pause at the bottom of the stretch for a count before pressing up.
  • Cutting the range short — go all the way down until you feel a full stretch in the calf and all the way up onto the big toe.
  • Rolling onto the outer foot — drive through the big toe side of the ball of the foot to keep the whole calf working.
  • Too heavy, too fast — calves handle high loads but they respond to controlled reps with a slow descent, not bouncing partials.

Calf raises go at the end of a lower body session or between sets of an upper body lift. Superset seated and standing raises to hit both parts of the calf back to back.

Frequently asked questions

What muscles does the Single Leg Smith Machine Calf Raise work?

The Single Leg Smith Machine Calf Raise primarily works the calves. It also involves the hamstrings and glutes, which assist the movement and stabilise the joints.

Is the Single Leg Smith Machine Calf Raise good for beginners?

It is rated intermediate, so it suits people who already train regularly. Beginners can still do the Single Leg Smith Machine Calf Raise with light load and a spotter or coach watching the first few sessions; if it feels awkward, pick an easier variation from the alternatives below first.

What can I do instead of the Single Leg Smith Machine Calf Raise?

If you cannot do the Single Leg Smith Machine Calf Raise, try the Single Leg Donkey Calf Raise, the Bench Donkey Calf Raise or the Supported Standing Calf Raise. Each of them trains the calves through a similar movement, so you can swap them in without changing the rest of the workout.

How many sets and reps should I do?

It depends on your goal. For the Single Leg Smith Machine Calf Raise, a sensible starting point is muscle growth: 3–4 × 10–15 per side with 60–90 s rest; endurance / finisher: 2–3 × 15–20 per side with 45 s rest. Do it after your compound lifts. It is a finishing movement, not the main event.
