When Liz and I got home from the Severn Across on Sunday, we both had achey legs, so after a walk round the park Liz said she wanted to have a go on the swings in the playground. So after we chucked the sulky teenagers off, we had twenty minutes of swinging and you know what? It's just the ticket for stretching out those battered glutes, quads and hamstrings. The only mistake we made was not bringing our own Diamond White with us.
