Wow! Now they are telling women 3-5 reps!
Looks like the old "more reps, lighter weight for tone" recommendation is completely busted, even for women!

"Erase Arm, Hip, and Thigh Flab
Old thinking: Lift for 12 to 15 reps
New approach: Pump out only 3 to 5
Performing just a few reps with heavy weights activates hard-to-tone "fast-twitch" muscle fibers that atrophy (hence the jiggly flesh) as you age. Problem is, many women use 3- to 5-pound dumbbells when they really should be using 10-pound or even heavier weights, says researcher William Kraemer, PhD, a physiology professor at the University of Connecticut. If you amp up your weight-training, you can fire those fibers and regain your strength and shape.
Improve results: Once a week (but no more—your muscles need recovery time), trade in your 3- and 5-pound dumbbells for 10, 15, even 20-pounders or heavier. Think it's too hard?Remember, you routinely pick up 10-pound grocery bags and maybe even 50-pound kids. Shoot for three sets, 3 to 5 reps per set. If you can't maintain good form, the weight is too heavy; pick a slightly lighter one."
Pump those women up!
