If you're male and an absolute beginner (as sitting in a chair all day implies), you can gain significant muscle mass with just 90 minutes a week of strength training. Can confirm, almost 3 year ago I started lifting and carrying around a weight. I started with a bit under 8 lbs and I lift 32 lbs now, and I've gained about 10 lbs of muscle mass and doubled my upper body strength. Mind you, it hasn't helped with weight loss. Eating her left overs has resulted in my gaining another 10 lbs of fat. :-(
