Help! I am 27 year old 5'5 female and I weigh 162 lbs. I have been working out for about 6 weeks at my local gym. My usual workout consists of a 2 mile walk/jog on the eleptical machine and then upper body workout using a few machines in the gym, and just started using 5lb free weights for my biceps. I try to make sure I work out 3-4 times a week. I dont really skip days on working my upper body (is this bad?) I am actually trying to get in shape for the first time in my life. I havent really changed my eating habits all that much (i really like to eat). My main concern is am I going to be making a difference in my body with the workout I am doing? Or am I going to be totally disappointed in another 6 weeks when I dont see much of a change? Can someone tell me what I need to do different? I would appreciate any input I can get.
