There must be a good balance between seeing gains and going up in weight while doing the same workouts each week, and changing up your routine in order to get some amount of muscle confusion. Currently, I do a different muscle group each day. M - Legs/abs T - Chest W - Back/abs R - Shoulders F - Arms/abs Usually stick to cardio or rest on the weekends. I like doing the same workouts each week to some degree because it's nice to see myself going up in weight, but what would be a reasonable amount of time until I switch up my routine to new exercises. Much appreciated.
