Re: Resting between reps - is it necessary?
No offense DSM18, but I think that's awful advice, especially assuming or implying that women should be lifting for cardio instead of working on lean muscle mass. Honestly, if you want to do cardio, stay on the treadmill. Weights are for getting muscle and tone. If you don't need rest between sets, then you are using too light a weight (like PhillyDude said, slowing your reps will increase the intensity too). If it's not a challenge then you're just going through the motions and not really going your body any good. What sort of workouts do you do?
