For about a year I stuck to basically the same routine using weight machines. I did 10 reps of 3 sets, for basically the entire upper body, 2-3 days a week. Recently a friend of mine told me that I need to switch up my routine as my body is probably used to this workout and it won't do me any good. So for about the last two months I have been doing free weights. Now I am working out each individual muscle group one time per week. I usually do 3 exercises per group at 8-12 reps, 3 sets. Is this enough? I feel like I have lost some muscle mass over the last few months.
