I Have Discovered the Perfect Form of Cardio for People Who Hate Cardio

Rucking involves walking with a backpack full of weights and carrying weights.

The name, and the practice, comes from the military.

Rucking proponents say it burns three times the calories of walking without a load.

They say it strengthens your back and shoulders, helps with bone density, and has a low injury rate.

At first , rucking lives up to this reputation: It sucks. But after a few days , I learned how to use the weight of the pack to pull my shoulders back.

GoRuck believes that rucking promotes good posture, but only if you do not fight the pack by straining forward.
