The class is hard – I don't pay mind to calories at all usually, but for comparison, my Apple Watch
tells me I burned 650 to the 450 I'd usually clock up in the same length spin class elsewhere – so there's no denying its effectiveness. The music is good, a playlist of contemporary pop, rap and '00s indie favourites, and the energy in the room is positive (we'll ignore the instructor taking the four candles to four individuals in the room to blow out – to make a wish? – during the slow ride at the end). I head upstairs for a smoothie (£6), which are tasty and the same price as at similar wellness establishments, and take a second look at the changing rooms which have luxurious beauty products like Le Labo shower gel, Drunk Elephant skincare, and Dyson hairdryers.
