OK folks. I have a question. I'm 48,and a PA flatlander. I will likely draw an Elk license for next fall and need to drop a few pounds. I'm not exactly a couch potato,but no long distance runner either. I train twice a week in the Martial Arts but don't worry too much about being 200 lbs. What I want to know is what can I do to maintain good muscle mass while dropping 20 or 25 pounds this year before hitting the hills of Colorado. Are there any suppliments maybe along the lines of amino acids or the like that will help while dieting and circuit training? I can hike and carry a pack along with my other exercises,but I don't run. Or jog for that matter. Cardio,weight training,martial arts and hiking are pretty much it. I hope to actually add a little muscle,but would settle for not loosing what I have at present. Any sugestions? Thanks .
