A little while back, in pursuit of an easy win, I bought an under-desk exercise bike which, as the name suggests, is basically a pair of pedals attached to a resistance wheel. Because it's always there, I sometimes find that I've unconsciously started pedalling. The bike that I chose came with a cycle computer, which displays the revolution count, RPM and calories burnt.
