Frequency
Also called training frequency, workout frequency
Frequency is how often you train in a week: either how many sessions you do, or how many times each muscle gets trained.
In plain words
The word has two readings, and they give different numbers for the same week. Count the sessions, and a six-day week is six. Count how often one muscle gets trained, and that same week gives each muscle two. A 2016 meta-analysis by Schoenfeld and colleagues says frequency can mean either. With volume matched, it found training a muscle twice a week grew more muscle than once a week; whether three times beats two, it says, remains to be determined. A 2024 meta-analysis of 14 studies and 392 people found split and full-body routines gave similar gains at equal volume. Frequency is a way to fit your sets into a week.
An example
Push, pull, legs, rest, push, pull, legs. That is six sessions a week. Legs come up on Wednesday and Sunday, so the legs have a frequency of two. The ACSM's 2009 position stand recommends 2–3 days a week for novices, 3–4 for intermediate lifters and 4–5 for advanced ones. Its 2026 stand found strength was better with two or more sessions a week.
