Kill your muffin top! All you need for this workout is a single dumbbell. I'm using a 5 pounder, but you can use anywhere from 2.5 pounds to 10 pounds. I'm not gonna lie, this routine is a little challenging, but I just know you'll love it! In Pilates Bootcamp, Cassey Ho takes you all the way through tough but fun Pilates workouts designed to tone your arms, your legs, your abs, your butt, and everything in between.
