Within a personal training sessions, how many sets do you do of the same exercise for a traditional circuit training session? Years ago the standard was 3, I see some trainers doing 2 sets and others just 1. What do you do and why?
I do 1-3 sets many times in a circuit style to keep the body moving w/o breaks. If the client is relatively new to exercise, its 20 reps, working our way down to around 12 reps if they can repeat the exercise with good form as we go heavier.
