Foam Rolling

I got one of these last week to help massage out some aches and pains and it's fantastic.

You sit, lie or prostrate yourself over it and basically roll backwards and forwards to massage out any knots, aches and pains. It is pretty uncomfortable at times, but it really helps, especially on your lower back.

It also seems to help avoid getting cramps if I spend a few minutes working on my calves before going to bed.
