I got my heart rate up!

The only exercise today was a 60min spin with 10x1min fast, 2min easy. I was able to get my heart rate up to 172 or so on some of the intervals which hasn't been that high in awhile. It felt great, too. The last time I was on a spin bike my legs felt dead and tired. I had a pretty good bike workout today. My ass was a bit sore still but it is getting better. Also, I've thrown away 3 pairs of tri shorts in the last week from them being worn out and see through. I'm sure most people don't want to see an outline of my junk flopping around when I run.
