well, i'm going to a gym to workout for the first time ever. i believe i should work out some sort of schedule, so i look like i know what i'm doing. cause whenever i look at people in a gym, they're always set on what they need to do. thing is--how should i begin working out? the treadmill first? then light weights...then maybe a machine? and for how long. i'm 5'11 and 160 pounds...i'm just looking to get toned.... any advice?
