Taking Sets Past Failure For Better Gains? | Educational Video | Biolayne

Why It Matters

The findings suggest coaches can achieve comparable calf hypertrophy with fewer sets by adding lengthened partials, offering a more time‑efficient training option, though its effectiveness for experienced lifters remains unproven.

Key Takeaways

• Full range of motion outperforms partials for muscle growth.
• Lengthened partials match full ROM gains with fewer sets.
• Study used untrained men; results may not apply to trained athletes.
• Adding lengthened partials after failure reduces total repetitions needed.
• Comfort and exercise selection limit practicality of lengthened partials.

Summary

The video dissects a recent calf‑training study that compared traditional full‑range‑of‑motion (ROM) work with partial repetitions performed in the lengthened position, and a hybrid protocol that added lengthened partials after reaching failure. Using a within‑participant design, each subject’s legs followed a different regimen, allowing a direct side‑by‑side comparison over a ten‑week period in untrained men.

Results showed that while full ROM remains the gold standard for hypertrophy, the lengthened‑partial protocol achieved identical calf growth with roughly half the number of sets and about 20% fewer total repetitions. The researchers matched volume load by counting each partial as a full rep, and participants performed two to three full‑ROM sets to failure followed by the partials.

The presenter highlights key methodological points: the untrained cohort likely exhibited an amplified training response, and volume differences matter less for novices than for seasoned lifters. He also notes practical concerns—lengthened partials can feel uncomfortable in movements like squats, though they fit naturally in pulls where the stretch phase aligns with stronger points of the strength curve.

Implications for practitioners are clear: lengthened partials are not inferior and can be a time‑efficient addition to calf programs, but claims of superiority should be tempered until similar data emerge in trained populations. Trainers may experiment with post‑failure partials to reduce set volume, yet must consider exercise comfort and individual goals.

Original Description

A new study (PMID: 42006449) examined whether or not training past failure on calf raises with partial reps after failure could enhance muscle growth.

This study didn’t replace full ROM… It ADDED lengthened partials after failure. And the result?

👉 Same muscle growth

👉 ~Half the number of sets

Translation:

You can get similar gains with less volume… IF you’re pushing sets HARD and adding lengthened partials.

But context matters:

• These weren’t sloppy reps

• They were taken past failure

• Total reps were actually LOWER

So no… doing lazy half reps isn’t the takeaway.

The real takeaway:

👉 Lengthened partials past failure may a way to increase efficiency, not a shortcut around effort.

Full ROM is still your foundation.
