Jennifer Aniston's Must Haves: From Viral Collagen Powder to a Microcurrent Device

Pvolve Gliders & Floorgloves ($34)

Don't let these fool you, Aniston cautions that they're dangerously effective, despite their compact design. "Not dangerous [per se], they just hurt," she jokes. "But I love them because if you've got a rug, you can use your glider. And it works your whole body, top to bottom — arms, core, legs, the whole thing."

Pro Tip: The space-friendly discs are great for those who are looking to maintain their fitness routine while they're on the go. Simply pack them in your suitcase or stow them away in a personal carry-on bag.
