The Claim

Both initial partials and past-failure partials are effective strategies for increasing medial gastrocnemius muscle thickness in resistance-trained individuals, with each producing medium to large hypertrophic adaptations over an 8-week period.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Challenges

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect

In plain English

If you're someone who lifts weights, doing partial reps either at the start of your set or after you've failed a full rep can help your calf muscle grow bigger over 8 weeks.

  1. Study: Resistance Training Beyond Momentary Failure: The Effects of Past‐Failure Partials Versus Initial Partials on Calf Muscle Hypertrophy Among a Resistance‐Trained Cohort

    Both ways of doing calf raises—starting with partial movements or pushing past failure with partials—made people’s calf muscles grow bigger, and neither was clearly better than the other.
