I won't argue about science. I'm 63 years old, I've been skating for two years. I weigh 235 pounds and have some health issues. These are hills I just could never climb, no matter how well I prepared, what gears I chose, etc. Now, out of five hills, I can easily climb four of them in a higher gear than before. Lastly, I now stand up without having to walk on it - so it works for me.
