Ive always been afraid of weights — don they give women big, bulky muscles?
Even when training with weights much heavier than those used in The FIRM workouts, most women lack the hormones necessary to achieve large increases in muscle mass. The reality is that only weight training can boost metabolism around the clock. (The post-exercise after burn from cardio also boosts metabolism, but the effect is comparatively brief.) Incorporating weights in your workouts will give you a more youthful, slim and shapely appearance.
