I am a 5'2" 125lb. 21 year old..... and I have not been active for some time now. I am looking to lose my belly flab and get in shape-- I lose my breath climbing stairs. I am not necessarily looking to lose weight (a few pounds wouldnt kill me thought) but to get toned and in shape. I am going to join the YMCA-- they have a student discount but I would rather do a routine here on campus for FREE. I was a member of the YMCA for a semester and I did like it when I did intervals on the treadmill then some sit ups and small weight lifting. I am interested in starting a routine for about 3x a week for 45-1hour each session at the gym.
I am lost in what will work best?? The cardio on the treadmill, some sit ups and the elliptical? Should I try intervals again? What should be my daily workout? Should I change my diet along with it? My primary goal is to get in shape where I can run around or climb stairs without being out of breath.
