Bouncing at the bottom
Pause one to two seconds in the stretched position so the calves, not the tendon, lift the weight.
Isolation · Machine
The standing calf raise is done on a machine with shoulder pads, raising your heels from a deep stretch. It trains the calves with straight knees, which favors the larger gastrocnemius, and suits anyone wanting bigger, stronger calves.
With the knees straight, the gastrocnemius does most of the work, with the soleus beneath it assisting. Pausing in the stretch reduces bounce from the Achilles tendon.
Pause one to two seconds in the stretched position so the calves, not the tendon, lift the weight.
Keep knees straight so the movement stays at the ankle.
Use full depth and full height on every rep, even if that means less weight.
Surpass starts the standing calf raise at 10–20 reps with about 1 reps in reserve. As an isolation exercise it fits well after your main compound lifts.
Work in 8-15 reps with full range and pauses, adding load when you hit the top of the range. Calves often respond well to frequent training, 2-4 times a week.
Surpass shows what you lifted last time beside a target for this set, and adjusts it from your reps and RIR. Free on iPhone, no account needed.
These train the same main muscles. Swap when the equipment is busy, something hurts, or progress has stalled for several weeks.
Standing raises bias the gastrocnemius; seated raises bias the soleus because the bent knee slackens the gastrocnemius. Using both is a good idea.
Common reasons are bouncing through short reps and too little volume. Slow full-range reps with a pause at the bottom, done consistently, help most people.
