Keep the exercises and the frequency. Either halve the sets (a volume deload) or drop the loads to 60 to 70% (an intensity deload). Do not empty the week; a week off the gym detrains the habit more than the muscle.
Plan one every four to eight weeks, before a test, and after a week where life did the loading instead of the programme. Signs a client needs one early: two sessions without progress, sleep off, joints complaining, RPE creeping up for the same weights.
Most clients feel worse in the deload week and better the week after. Warn them.
