Is treadmill walking as good as outdoor walking?

🤔.........I'd say yes. Maybe better since you can adjust the speed. It all comes down to what type of surface your walking on and the shoes you're wearing. Walking is good for a person. Running is the best exercise for burning calories, but the worst exercise because it's high impact on you body. it's hard on your joints..........Before my heart condition and I was in great shape, I mean I was thinking about training to compete in a 1/2 Iron Man. I ran out doors and I use to run all the on the treadmill. Turn on the Avalanche game and run an entire period, Take a break during intermission and then back on the treadmill for another period.........
