Sarah, I tried the HR monitor throughout my entire workout today and was pleasantly surprised. My entire workout was on target according to my heart rate monitor. Funny how the body naturally knows.

The only problem was my 6s b/c my heart rate wouldn't lower to 60% of maximum HR coming off my 9s. But during my warmup, my heart rate was at 60% so I didn't change it. Is that what you found?

It's a good way to gauge when to increase intensities. Cool!

Thanks for your input!

Wanda
