Want to train with weights like characters from Dragon Ball Z? In real life, the military special ops regularly use weighted rucks to train, carrying heavy loads over miles of rough terrain. If you’re that kind of badass, you’ll be excited about the Rogue Load Trainer, a simple design that changes the game for this type of training. A Navy Special Warfare Operator designed the Rogue Load Trainer to take Olympic-sized weight plates on a traditional Alice frame.

The weight sits on the upper middle back, the sweet spot to reduce related injuries and back strain. A hitch pin keeps the plates firmly locked in, and the weight won’t shift around even when sprinting. Each Rogue Load Trainer comes with a lightly used Alice pack, complete with padded shoulder straps and a kidney pad. It’s manufactured in the USA from solid metal, and you won’t find another like it on the market.
