>>2191Start by walking 15 minutes. Once you can make that at a steady pace without stopping, gradually increase the time to 20 mins, 30 mins etc. once you can walk without stopping for a good while, without running out of breathe, then try making one mile. Do 1 mile for a whole week and if you can make that easily then add another mile the next week and keep building it up week by week until you hit you 3 mile target. You need to be consistent to build stamina. Ideally, you should walk at least 5 days a week and take the weekends off for rest. Make sure you wear good, well fitting athletic shoes or boots (army surplus is a good option) and loose well fitting clothes that are weather appropriate.
Remember, you're not running a marathon race or going on a mountain hike, so don't walk super fast or march around. You want a steady, brisk pace. Just a regular walk at a gentle speed but not so slow you're moving like a turtle. Remember to breathe in through your nose and out through your mouth, deep breaths. Inhale as you take 3 steps, then exhale for 3 steps. If you're still having hip issues, you should go to a doc and get that checked out.
