I'm not sure which exercises are better, but I can guarantee that lifting weights in the offseason will help when you fall. During the two past seasons, one of which I was working out during, I felt a big difference when I was going fast and happened to eat shit. I could get up and shake it off in a second after I had worked out. When I was less in shape, I would get the wind knocked out of me and had to take a few. I probably should be doing some stretches, I can see why that's beneficial, but ehh.
