I've found that the "meat heads" tend to be super helpful to newbies, especially women. They are full of pointers on proper lifting, form, how to increase, protein, and on and on and on. Surprisingly so, really. The runners/walkers tend to be in their own zone and not have much to offer, but the weight lifters LOVE seeing new meat trying to get healthy and fit. You'd be surprised by the welcome you'll get over there.
And seriously, if the thought of lifting at the gym intimidates you, your really should check out Body By You.
Today is a new day to try again. At least walking in the door was step one. You can do this!!!
