I'm 5"6 & weigh around 120 lbs. I am trying to build muscle but because of my anorexia I am limited to what I can do. I am allowed 3 hours of exercise a week & I am eating at maintenance. I have been doing a 3 day push/pull/leg split & 30 minutes of cardio 3x a week(12 minutes of interval training & then moderate intensity cardio). Any suggestions please help? This is only my 3rd week weight training.
