You sound like a Jordan Tootoo kind of a guy. Low center of gravity, and plenty of weight to throw around. Thats what im trying for. Except im 5'11" 230, with probably 20%bf. Anyway, i have noticed that oblique work helps a lot with stability when skating and hitting. The leg lifts have helped me too. Ever since I started focusing more on abs I have had less back pain too on the ice. Its amazing how important abs are in hockey, and overall back health. BTW, PM me, how old are you? where do you play,level etc.?
