The Importance of Mobility Over Strength

I'm really focusing on mobility and I mean just the idea that imagine if you fall over and that you couldn't get yourself up, it's pretty scary. My father fell over while his wife was out and he was on the floor for like 40 minutes and couldn't get up. He'd been quite fit actually until he's mid 60s and then he stopped exercising and didn't eat. "Walking a lot and being out in nature is a great alternative to this idea that you have to go to the gym and crush it"
