What you will be doing
Torch 700+ calories. This is raw and rough. If you’re looking for a fitness masochist class, you've struck gold. Prepare to be dominated. Scream if you wanna go faster. Get punished if you stop. Every deranged, power hungry Londoner welcome.
It's a secret. SHH! Come and get absolutely annihilated. No safe words allowed.
You'll need water. Possibly gallons.
