Last-Minute Prime Day Deals Up to 60% Off — Including Apple, Dyson, and More

Renoj Store Resistance Bands Exercise Bands Set ($8, originally $10)

These bestselling loop exercise bands have a fan in pro tennis player Tommy Paul — and they're 29 percent off for Prime Day. Shoppers love that they're compact, easy to store, and simple to pack for travel. They're also a handy way to add resistance to strength workouts. "You can grab them pretty much anywhere, and they're unreal for warming up before practices or matches," Paul shares in an interview with Popsugar. "Honestly, it can be harder than the actual lift itself."
