Standing calf raise
The standing (straight-knee) calf raise is the best-supported calf builder: with the knee straight the gastrocnemius works at long lengths, and in a 12-week MRI trial it grew far more than with seated raises. Calves are stubborn, but several small trials show they grow with enough sets and a deep stretch at the bottom.
What the science says
- Grows the calves more than seated raises Moderate evidence
In Kinoshita et al. (2023), 14 untrained adults trained one leg standing and the other seated (5 × 10 at 70% of 1RM, twice a week, 12 weeks). MRI showed the gastrocnemius grew 9–12% with standing raises versus under 2% seated; the soleus grew similarly with both (2.1% vs 2.9%).
- The stretched bottom range matters most Moderate evidence
Kassiano et al. (2023) trained 42 young women for 8 weeks: partial reps in the stretched half of the range grew the medial gastrocnemius by 15.2%, versus 6.7% for full range and 3.4% for the top half only.
- More weekly sets, more calf growth Moderate evidence
Kassiano et al. (2024) compared 6, 9 and 12 weekly calf sets in 61 untrained women over 6 weeks; all grew, and 12 sets beat 6 for the lateral gastrocnemius (+14.3% vs +8.1%) and soleus (+12.7% vs +6.7%).
- Toe angle shifts growth slightly between heads Limited evidence
Nunes et al. (2020) found that toes-out favoured the medial gastrocnemius and toes-in the lateral head in 22 young men over 9 weeks; a single small trial, so a minor detail at most.
How to do it
Muscles trained: gastrocnemius, soleus
- Stand with the balls of the feet on a step or platform edge, knees straight but not locked.
- Lower the heels as far as you comfortably can and pause 1–2 seconds in the stretch.
- Rise as high as possible onto the balls of the feet.
- Don't bounce out of the bottom; the stretched range is where most growth came from.
- Keep weight over the big toe and second toe rather than rolling outward.
How to apply it
Train through the full range with a pause in the stretch, take sets close to failure, and give calves as many weekly sets as any other muscle.
Who should be careful
For healthy adults the main risk is Achilles or calf soreness from adding deep-stretch volume too fast; build up over a few weeks. Anyone with Achilles tendon pain or a past rupture should have a physician or physical therapist set their training.
Frequently asked questions
Standing or seated calf raises for bigger calves?
Standing. In a 12-week MRI trial the gastrocnemius grew 9–12% with standing raises versus under 2% with seated raises.
Should I do partial reps for calves?
Partial reps in the stretched bottom half grew the gastrocnemius more than full reps in one trial; full range with a deep pause is a sound default.
How many sets do calves need?
In one trial 12 weekly sets beat 6 sets; aim for about 6–12 or more hard sets per week.

More exercises
- Back squat Strong evidence
The barbell back squat reliably builds the quadriceps, glutes and adductors and is one of the best-studied lower-body exercises in training research.
- Front squat Moderate evidence
The front squat holds the bar on the front of the shoulders, which keeps the torso more upright and loads the knees less than the back squat while recruiting the thigh muscles about as much.
- Bulgarian split squat Moderate evidence
The Bulgarian (rear-foot-elevated) split squat trains one leg at a time and builds the quads and glutes with far less load on the bar than a back squat.
- Leg press Strong evidence
The leg press builds the quadriceps about as well as free-weight squats and also grows the glutes and adductor magnus, with no balance or spinal-loading limit.
- Hack squat (machine) Moderate evidence
The machine hack squat lets you squat deep on a fixed track with your back supported, which makes it easy to push the quads close to failure.
- Romanian deadlift Moderate evidence
The Romanian deadlift is a hip hinge that loads the hamstrings and glutes at long muscle lengths, and trials of stiff-leg deadlifts and similar hip-extension exercises show real hamstring growth, mainly in the semimembranosus and biceps femoris long head.
