Hula hooping after morning run

I had a wonderful morning run. 
Before cooling down, I love hula hooping for about 5-10 minutes. It's really a great warm-down exercise. During run, my heart rate is about 140 beats per minute (plus minus). While hooping, my heart rate is about 110 beats per minute (plus minus). So, before going straight to stretching after my run, i will just hoop for short 5-10 minutes. Yay!
