As I venture towards my weight loss goal, my brother will be filming me along the way. Today I had to, repeatedly run up and down hills and on muddy trails in the freezing cold as he tried to capture a few moments of what I am doing to lose this weight.
HIIT is like Buckley's Cough Syrup. It's aweful and it works. I find interval training to be about 90% mental and 10% physical and your results really depend on how hard you are willing to push yourself. If I don't feel a little dizzy after a workout then I don't feel like I worked hard enough.
Don't be afraid to push yourself. Get a coach if it helps. I have a camera following me around. So I can run, but I can't hide.
