Product Overview
Turn your workouts into works of ART – Active Resistance Training, that is. With Synergee’s heavy duty, tough-as-nails Synergee Resistance Training Backpack Cast Iron Walking Ruck Weights, it is simpler than ever to become a lean, mean, healthy machine. All you need is a bag that can hold 1 or more Synergee Ruck Weights – and then put one foot in front of the other and take them for a walk!
Forget the treadmill. Grab a friend or go alone; walk around your neighborhood or somewhere you’ve never been before; expand your brain and listen to a Podcast as you go; explore the world around you and burn 3x’s more calories than you would walking normally.
Too hard? Use a lighter weight. Too light? Add more lbs. It’s simple and effective and can be done anywhere. Rucking is especially awesome for people who hate cardio: if trying to get yourself out on a run is more painful than stepping on a piece of Lego, pick up a Synergee Ruck Weight instead. Burn calories and gain strength at the same time.

Features
•SIMPLERucking is simple. Put some weight in a backpack and move with it. And keep moving. Keep putting one foot in front of the other. Keep it simple. Make it happen.
•STRONG & LEAN
Rucking with the Synergee Ruck Weight is a type cardio for people who hate cardio because it’s part cardio, part strength training. Rucking is a work of ART: Active Resistance Training.

•INDESTRUCTIBLE
Synergee Ruck Weights are constructed with cast iron that bears a break strength of 90,000 lbs. Each weight is coated in a rust resistant black matte coating.
