I’ll look manly if I lift heavy. Ever heard that before? Or maybe you’ve even said it yourself? Women tend to become “cardio bunnies” or “core junkies.” They spend hours running, performing hundreds of crunches, and lifting 5-pound weights to “tone.” Still sounding familiar? Those 5-pound weights might build up some endurance, if you do it long enough, but they’re not building up muscle or strength. And in the long run, that is actually what you want!
