6'5", increased 10 pounds to 210 since I started eating and working out 2 months ago. Goal: Gain muscle mass. I've been doing a 3-4x a week full body workout. Just went in for a new program and have planned a 2x Upper 2x Lower body workout a week. After my first workout on new program I'm feeling the soreness like I had when I first started 2 months ago. I don't want to delay my program, but should I rest for a couple more days or ignore it and work out?
