Start eating high fiber foods.

It’ll save you money and make you lose weight because it takes forever to digest. That makes the walking easier, and won’t hurt your joints as much.

Like, if you’re gassed after walking 20 minutes, you don’t need a weighted vest for a while.

When you can walk 20 minutes and have the same level of energy as you started, then start thinking about stuff like carrying a heavy book, or anything that’s roughly 5-10lbs.

Don’t overthink it. You’re just making it slightly harder everytime what you’re doing gets too easy.
