area 1 is all 260 and below. area 4 is all 270 and above. The rest have hi and low. A3 probably has the best mix.Thanks for the response Scope Dope. Do you work out at the center? Can you tell me a little about the different areas in the center? I've heard there are 6 areas and one area is all high and one all low. Thats about all I know. Are the others a balanced mix of highs and lows? Thanks.
