FLEXR FOLDING PULLUP BAR
Everyone knows the value of a good chin-up or pull-up set, but many hotel gyms don't have what you need to stick to your body weight regimen. Innovating on the now-classic design of door-frame mounted bars, the Flexr Folding Pullup Bar is a surprisingly travel-friendly option. It collapses down into a bundle that can fit in your daypack or desk drawer without a second thought. The build is sturdy, with bent steel, aircraft-grade aluminum, and injection-molded plastic components, yet weighs just six pounds, so it's fine for slipping in your checked bag.
