Meh, experts are always come up with the new improved solution to fitness. I say the best solution is to experiment and listen to your own body.

For me, variety is the key. Once my body gets used to something, I need to change it up. Hiking, jogging, sprinting, swimming, biking, jump roping, lifting, super-setting, cross-fitting. They're all part of the mix. I find my knees, ankles, and other body joints, function much better when I incorporate jogging or jump roping into my routine, as long as I don't overdo it. I think my body's build naturally wants these activities.

In contrast, a body that is built like a boxy Strong Man is probably going to respond well to flipping truck tires everyday. I'm not built like that.
