If you want to gain muscle, consume ALL the protein. Beans, tempeh, tofu, seitan, soy milk with EVERY SINGLE MEAL and throw in some protein shakes and protein bars for extra effect. Go to the gym. Run a mile, do a couple full body resistance exercises to failure, a few reps each. i do bench presses and squats. Repeat over and over again, increasing the weight when you can do so without sacrificing form. Add additional exercises over time as you build discipline. You'll look like Ronnie Coleman in no time.
