That's encouraging Phil. I'm finding the aerobic cooldown at the end of sessions is equally helping.
As well as the intensity of training, I also found the duration of the training is a factor. I almost always spiked when I went from spinning to circuits (2hrs). That wasn't always the case when I just went spinning (1hr) or just circuits (1hr).
