I am currently a 19 year old male who is 6'1" & approx. 170. I am pretty skinny all around with a bit of a gut. i would really appreciate any advice. Over the past few years, I have tried constantly to gain weight/muscle mass. I played football in high school and that consisted of weight training 3-4 days a week. I am now a sophomore in college and still struggling to add something on, while losing the gut. I'm stuck in a battle because if I run and eat less, I won't put on anything. And if I eat and lift...nothing. I can't seem to get results through anything. What can I do to finally see results? What kind of workout routine do you recommend? Full body workouts or certain areas on certain days? How much cardio? What and how much to eat? Is there anyone else who has been through a similar struggle? I feel like I've been working at it a while with no results. I'm guessing maybe I'm doing something wrong or just don't know enough about fitness. My usual routine is a full body workout 3 days a week with a jog on the off days. Again, any help/advice is appreciated. Thanks.
