The Deal

• $25 for eight weeks of gym membership ($70 value)

Eight weeks of a gym membership to National Fitness may leave you wondering why workouts often do different things for women and men. Women’s strength-training classes often promise results such as a toned, slim, or defined body—but they almost never promise to add bulk. Yet these very same workouts do just that for men. That’s because although a rigorous strength-training routine can help a woman boost her endurance and lower her body-fat percentage, it won’t help her develop big, bulky muscles (not without anabolic steroids, anyway).
