"The Crossrope Get Lean Set ($88) comes with two jumpropes of different weights. You can jump around with them for some quick cardio or open Crossrope's app for hundreds of workouts, including HIIT, strength, and more cardio. Crossrope sent me the set to try out, and the few workouts that I've done so far were fast, fun, and great for cold days when you want a workout without leaving the house." — Maggie Ryan, assistant editor, Fitness
