Here is a backpack that lets you workout anywhere. The EMPACK replaces your weights, allowing you to add more intensity to your workout routine and build strength. You can use the water bladders to add more weight to your backpack. The backpack has multiple handles and lets you perform dead-lifts, weighted squats, lunges, and other moves.
Since the EMPACK has a portable design, it lets you try weight training outside without having to worry about carrying kettlebells and dumbbells. Like what you see? You can find out more about it on Kickstarter.
