This claim is based on a meta-analysis, the most robust level of evidence for synthesizing existing data. Research does indeed confirm that for an equal total volume, spreading the work over multiple sessions seems to promote muscular adaptation, notably through more regular stimulation of protein synthesis. The specific point regarding the upper body is consistent with physiological observations, as these muscles often recover faster than the large muscle groups of the lower body. It is important to note, however, that the advantage of high frequency decreases if the total volume per session becomes too exhausting or compromises the quality of execution. This advice is therefore an excellent basis for optimizing one's routine, without frequency becoming the sole factor determining progress. Greg Nuckols synthesizes the data here with precision, avoiding overgeneralizations.

What’s uncertain
For a matched weekly volume, frequency is largely personal preference. Training twice or more per week is at least as effective as once, and can make it easier to accumulate volume with good technique.
