I headed down to Gymbox Victoria for a lunchtime Weight Lifted class. The sessions are offered at seven of Gymbox’s London locations and usually take place around midday – ideal for relieving the stress that’s built up from a morning at work.

The classes tend to be small – there are seven mats laid out when I arrive, but there are only five of us present by the time the class starts – which is kind of ideal when you’re trying to relax.

The atmosphere in the room is designed to be relaxing, with the lights switched off and LED candles laid out on the floor around you.

Now, Weight Lifted incorporates several different disciplines, so it’s hard to know exactly how to describe it. On the Gymbox website, it’s sold as a “safe, screen-free space to shake off the day… literally” which combines “therapeutic tremoring, tension release exercises and deep relaxation”.

“The only aim is to leave feeling a little lighter,” the description concludes.
