Sitting under the Smith bar with one bent leg working at a time isolates each soleus against a bar you can load precisely and rerack with a flick of the wrists. Choose it over the two-leg seated version when one calf is visibly behind, since the fixed path makes side-to-side comparisons unusually clean.

How to do the Single Leg Seated Smith Machine Calf Raise

  1. Sit on the machine with your back against the pad and your feet on the footrest.
  2. Place one leg on the footrest and keep the other leg off the footrest.
  3. Using your calf muscles, raise your heel as high as possible.
  4. Pause for a moment at the top, then slowly lower your heel back down to the starting position.
  5. Repeat for the desired number of repetitions, then switch legs and repeat.

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.

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.

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

If you cannot do the Single Leg Seated Smith Machine Calf Raise, try the Single Leg Donkey Calf Raise, the Plate Barbell Seated Calf Raise or the Plate Dumbbell Seated Calf Raise.

How many sets and reps should I do?

For the Single Leg Seated 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.
