Running a session

When the equipment is taken

Swapping an exercise when the rack is taken, without leaving a hole in your training week.

Someone is camped on the rack. Swap the exercise from within the session and Mettle offers alternatives that train the same thing with the equipment you have.

Because the engine tracks volume per muscle across the week rather than per exercise, a substitution keeps your week intact instead of leaving a hole.
