hi cosmogrl...thanks for the reply....
i see results, so i'm not really worried...i just keep hearing people talk about the need to switch it up (kind of like needing to change your shampoo and conditioner every few mths) but i wasnt sure if it was a myth or there was actually some truth to it.....excuse my ignorance, but what is circuit training?....
certain areas of my body show muscle faster than others...i guess that's normal....my arms, for example....whereas my legs/butt take longer to respond....i was wondering if that had anything to do with the fact that i tend to do the same workout and so my body isnt being pushed in new ways.... ??
