Do you give your clients a full body workout each session, or do you split your routines up into upper body one day, lower body another day, or alternate upper and lower body exercises each day while working different muscle groups each session so that by the end of your second day session the entire body has been covered? I’ve heard people mention doing push muscles during one session, then pull muscles during the second day session. Which muscles would be considered push muscles, and which would be considered pull muscles to design a class this way?
