I have been going to this exercise class for a few years now, and couldn’t recommend it more highly. ‘Bootcamp’ is a bit of a misnomer: it’s quite tough, and you get properly out of breath, but you can take it easier if you want to and there’s certainly no sergeant-major style shouting. Adele continuously varies the exercises and introduces new routines, so you never know quite what you are going to get each morning. And the park is beautiful in all its moods.
