Standing Calf Raise

You bounce out of the bottom using the tendon rebound instead of the calf muscle.

You cut the rep short at both ends, never fully stretching or fully rising.

You bend the knees to help the weight up, which shifts the work off the target muscle.

Pause for a full second in the stretched bottom position to kill the bounce.

Rise as high as you possibly can and squeeze, like standing on tiptoe to reach a shelf.

Press evenly through the big toe side of the foot rather than rolling to the outside.
