Even though one method showed a tiny bit more muscle growth, it was so small that it wouldn’t make any noticeable difference in how your arms look or feel.
Scientific Claim
The difference in elbow flexor hypertrophy between traditional training and Tonal 1 drop-set training is statistically significant but falls below the pre-registered threshold for practical relevance (0.14 cm), suggesting the advantage is not meaningful in real-world settings.
Original Statement
“Elbow flexor hypertrophy was significantly greater in TRAD ... however, the contrast between conditions was considered practically equivalent as it did not exceed the preregistered smallest effect size of interest (0.14 cm).”

Investigating the Effect of the Tonal Drop Set Mode On Elbow Flexor Hypertrophy
The study found that traditional lifting made muscles slightly bigger than Tonal’s drop-set method, but the difference was so small that it doesn’t really matter in real life.
