KCee You could try an electric cart, but for me that really only helps on those uphill grinds our course has on the back 9. Downhill is easier on the lungs but harder on the knees and ankles for me.
The push cart feels weightless to me and I don't notice the hill climbs from a cardio standpoint. The knee just hurts walking downhill......pushing a cart, just walking the dog or unloaded except for my extra weight. We'll see if the brace helps.
