Why: "The chest muscles (pectorals) for all women are particularly weak and underdeveloped," says Perkins. "By increasing the mass in this muscle group you are adding a substantial percentage of lean mass towards your overall health. Additionally, the chest muscles are responsible for supporting breast tissue. This move will bring a bit more lift to your chest."
If you’re new to weight training, don’t worry. Perkins created this four-week program to help you to build a solid foundation of strength training and shift your body into a new place after all that cardio. The really great news? You only have to do this routine twice a week. Each week, the moves will stay the same, but we'll make the routine harder by changing the program variables (like rest, sets, reps, or load).
