Seems like I must have done it right yesterday. I am not sore, I just have a mild awareness of my muscles, which could be a good sign or bad one if it means I didn't do enough. Should the latter is the case, there's always tomorrow, when I make my next appearance at the gym. I'm torn between adding resistance, and adding another set. I might get really ambitious and add both. Either way, I'm not in any danger of overdoing anything yet. I also intend to keep my workouts not longer then 90 minutes, preferably about 60 minutes.
