slobber: You inadvertantly proved the anti-aerobics stance. Jumping rope does NOT fit into the definition of aerobic. Aerobic is along sustained, low intensity activity. Robe jumping for one minute intervals is most definitely ANerobic -- closer to weight lifting where the HR jumps up quickly but only for a short while, which is MUCH BETTER for heart strength. Weight training IS cardio! (but prentend I didn't say that or all the pro-aerobicisers heads will explode).
DTOX: Get ready to retract your statement. I've spoken to many pros and although some still engage in aerobics (nobody said they were smart) many of them use a "circut training" type of workout. Higher reps, short rest etc.
Using the methods of the pros is absurd anyway. Their goals is to look good on a particular night, by any means possible. That has nothing to do with what most BB's do.
