Its all about technique! Just dont start waxing your body to gain a second or two for actifit😆
I spent many years as a youth playing American football and doing a lot of jogging on pavement. My chiropractors over the years tell me to just do an elliptical and not jog. (Bad knees and spine)
But to be honest with you I do miss running on the bleachers up and down.
My knees have been fine so far. I do wonder if shoes with less cushioning would give less protection. Some people run a lot more than I do and wear themselves out.
The endorphin rush is no joke.😄
