"Working out from home can get boring, especially since I have minimal equipment. These Fit Simply Mini Resistance Loop Bands ($12) have added a challenge to my normal bodyweight moves, and I've gotten sore by using them for squats, glute bridges, and more. They are small and lightweight so they are easy to store and travel with. Plus, for $12 for a pack of five, you can't beat the price!" — Christina Stiehl, senior editor, Fitness
