HeartcastleHave a look at my skiing here... and this is on rock hard morning groomers. The ski shape has its limits on this snow at these speeds... you'll see the tail shuddering. But I can assure you, my knees felt absolutely fine. The only issues I have is that pulling fairly high g's all day... you need to have a fairly strong, straight back. But at least I can build that up with surrounding muscles (such as doing Yoga) .. knees aren't muscles. They really are basically a 1 directional hinge. That should be respected.
harryjoeThere are lot of benefit of jogging and exercise,it keep you safe,healthy and stay away you from different diseases.
