How it works: Three or four days a week, do 1 set of each exercise back to back, with little or no rest in between moves. After the last exercise, rest 1 to 2 minutes, and repeat the full circuit 2 more times (3 times total).
You’ll need: A pair of 2- to 3-pound dumbbells, a pair of 15- to 25-pound dumbbells, a resistance band, and a pull-up bar or Life Fitness Machine.
Grab a pair of 2- to 3-pound dumbbells and stand with feet hip-width apart. Take a slight bend in knees as you shift hips back and lower torso until it’s parallel to the floor. Bring weights together and turn palms to face forward. Keeping arms straight, lift weights up to shoulder height then lower back down. Make sure to keep core and glutes engaged the entire time. Do 15 reps.
