I’m a believer. At 72 I walk, run some, lift weights and do planks, etc. I’ve been doing a 3 mile walk with short runs interspersed along the way 3 days a week. Last weekend I went to a school track and took off to see how far I could jog. Made it 3 miles without any walking, was shocked.
Yep if people take the time and do it a military gait walk will
give you good exercise for both muscles and breathing. jmo.
Being a working stiff still, this means I'm up at 0415 on weekdays to get this all done before my workday starts. You get used to it.
