^That is high! Running is hard though.. I can only jog about 4mph as it is so hard on my knees after awhile.

My hr was around 175 which is quite high , I was looking at my garmin while I was spinning. I think my MHR is about 180 or 190, Nev.

This is spinning, Edmond. I was in this class as someone taped it. This was in Shanghai at Spacecycle. It is a high intensity indoor bike ride basically using spin bikes often with lights and music. I did Spin class alot when I lived in China. You get to see some butts in this vid. lol.
