Suspension training can be very hard but with four straps instead of the usual two, the Trufit Quad can make suspension training a even harder thanks to moves like the Quad Pushup, the Skydiver and others. The world record for the highest number of Quad Skydiver repetitions, at the time of writing, is only twenty but if you can only do six, you've got nothing to be ashamed of. It's not designed exclusively for super fit athletes though. If you're a beginner, you can do moves that even a seventh-grader can do and progressively graduate to harder moves as you get stronger. You don't have to use all you straps when you're just starting out.
