Wow, I forgot how much a good trainer session makes you sweat, and turns your legs to jelly pretty quickly.
Tonight I rode for 35 minutes, a 25 minute spin with 5 minute warm up and cool downs on either end. It had been a while since I had last used it, and even though I thought I was all set up, the one thing I forgot was the strap to my HRM. That device really helps me keep the tempo up since I can see exactly how hard I am working. Without that I tried timing my revolutions and trying to keep it up pretty high.
I did one standing stint (something I haven’t done much of on the trainer). That sure made the quads burn.
