Hold a medium-weight kettlebell or dumbbell at your chest, core tight, feet about shoulder-width apart. Keeping your core tight and chest up, lower into a squat, going as deep as is comfortable. Stand back up, but pause when your thighs are parallel with the ground. Hold for one second, then stand all the way up, squeezing your glutes. That’s 1 rep; do 3 sets.
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).
