In a Nutshell

Training to failure with full-ROM calf raises, then adding lengthened partials to a second failure point, produces the same hypertrophy as straight full-ROM sets when total hard reps are matched. The partials simply let you reach the same rep count in fewer sets, making the session shorter. Beyond-failure techniques linearly boost growth per set but exponentially raise fatigue, so they’re only worthwhile when recovery isn’t limiting; otherwise, stopping at 1–2 reps in reserve remains the better stimulus-to-fatigue choice.

A big real-world problem is that lots of lifters think they're near failure, but often they're not as close to failure as they think. Training past failure with partials will absolutely make any given set more anabolic. It linearly increases the growth, which is sweet, but it exponentially increases the fatigue, which is not sweet. The study's purpose was to test the key question: are beyond failure lengthened partials intrinsically better or do they just increase muscle growth by just making you do more work?

The study title is "Does performing partial repetitions beyond momentary failure enhance muscle hypertrophy in volume load equated calf raise resistance training?" The authors include Amirali Golie and Sajjad Ahmadizad. It was published in 2026 in the International Journal of Exercise Science.

Muscle growth can be influenced by many training variables, such as how much volume you do, how many sets, how much weight is on the bar, the load, the range of motion, the rest times, and how close you get to momentary muscular failure, truly can't do another rep type of grind. Researchers are interested in beyond failure methods like drop sets, rest-pause, cheat reps, and partials after failure to see if there's something in that beyond failure close to failure condition that squeezes out more growth. Lengthened partials have received attention for being vetted in multiple studies as doing as well or sometimes better than full range of motion and definitely better than partial at the shortened position training for hypertrophy.

A recent study by Larson and colleagues found that beyond failure lengthened partials looked better and caused more growth. However, they did not equate for volume. The lengthened partial group did exactly the same workout as the normal full range of motion group, just did lengthened partials afterwards, and so just slapped more stimulus on top. This study tests whether beyond failure lengthened partials are intrinsically better or just increase muscle growth by making you do more work.

The two conditions compared were sets of full range of motion taken to failure versus the same full range of motion sets taken to failure, and then partials to a second failure point in that stretched partial range. The full ROM failure then partial failure group did calf raises until they couldn't do calf raises anymore, then did calf raises right after until they couldn't even raise their heel to parallel to the stepper. The full ROM only group just stopped at full ROM failure. The full ROM only group was able to do more sets so that the total amount of repetitions done with the full range of motion group and the full ROM plus partials was the same.

The researchers hypothesized that overall hypertrophy would be similar when you matched the number of very difficult reps that you're doing, the total reps done. They also suspected that full range of motion plus post-failure partials might be more efficient per set because the partials don't require as much movement, you can't do as many of them as you can a standard set, and they occur after already a pre-fatigued muscle.
