Funny things, bodies. This one of mine, for instance, generally feels wearily heavy when I get it onto the elliptical training thingy in the gym, but it actually felt quite energised this evening, despite a wearisome week at work. However, despite my sense of feeling full of the proverbial beans, and going at it hammer and tongs, as it were, I still posted numbers which, though good, were not my best.
I also managed to get my heart rate up to 171 or thereabouts, which, according to the machine in question, is regarded as the top rate for those in their twenties. Gosh. Not exactly sure I should be going into that range, but I appear to have survived. Sort of.
