Training frequency
Training frequency is how many times per week a muscle receives direct work. It is counted per muscle, not per client: someone training six days on a body-part split can be at frequency 1 for each. For the same weekly volume, splitting it across more sessions holds the quality of each set better.

In practice
It is the cheapest lever once volume is already high: the same 16 sets across two days return more than stacked into one, without the client training more hours.
The common mistake
Raising it without cutting sets per session. Doubling frequency while keeping the same work per day doubles weekly volume, which is a different change from the one intended.
