Calf work runs long, so start by sizing the sets
Choose how you perform the raise, then enter body weight, added weight, a target rep total and reps per set. The page returns load per foot, the sets needed, the actual total reps and total load lifted. On two feet the body weight plus added weight is split across both; on one foot all of it sits on that foot. Sets are rounded up because the target has to be covered, so the actual total can land above the target, and that gap is shown too.
Total load lifted is load per foot times actual total reps. For single-leg work that figure is per foot, so both feet together is double. High-rep calf work is widespread practice rather than an authoritative standard, and as of October 2026 no published rep or set standard for calf training is available, so both values stay as inputs.
The load is simple arithmetic on body weight, so it does not model the force actually passing through the ball of the foot, ankle angle or range of motion. No grade or level is assigned. If your Achilles tendon hurts, stop adding reps and see a clinician.
Frequently Asked Questions
No authoritative standard is published. High-rep work is simply common practice, so enter your own target total and reps per set.
Because the target total has to be covered. When that pushes the actual total above your target, the extra reps are shown as well.
The figure shown is per foot, so both feet together is double. The result line says so explicitly.
