Are you cardio-ing yourself to death? Yes, running, cycling, and hitting the elliptical religiously can absolutely help you reach your goals, especially if you're looking to lose weight. But, at some point, you're going to hit a plateau, says Holly Perkins, C.S.C.S., founder of Women's Strength Nation and author of Lift to Get Lean.
To get past it, you need strength training in your life. Why? Lifting weights helps to amp your metabolism for long after your gym-time ends since the more muscle you have, the more calories you torch when working out and while sitting perfectly still. Not to mention, strength training is a great way for women (and, well, everyone) to steer clear of injury; the stronger the muscles surrounding and supporting your joints, the more you'll be able to maintain good form and keep out of harm's way. And, of course, lifting weights can — and does — make you strong AF (without causing you to "bulk up"). (Related: 11 Major Health and Fitness Benefits of Lifting Weights)
