How often a muscle needs training for maximum hypertrophy

Methodology

Systematic review with meta-analysis

Findings

When weekly volume is matched, the effect of frequency on muscle growth is limited.

Practical conclusion for REZA

The split across the week is chosen based on schedule and recovery, not because a particular frequency is inherently better.
