Just in time for the weekend, Coach Jerry says to take your workout outdoors with this simple way to stay in shape and maybe even charge your mental batteries. All you need is a rucksack (or a backpack) and a little bit of weight.
You can scale this workout according to your fitness level, starting as low as 30 minutes with 15 lbs and going as long as 2 hours while rucking 35 lbs.
