The sprung floor could be a vaild point actually.. if you were working out in a gym with a sprung floor, it would make you think "hey, i bet i could sidehop over my best in here, lets give it a go"
Besides if you look in the mirror in the background, it looks like a gymnasticy-gym, as opposed to a standard UK weights & CV gym.
amasing sidehop though, didnt use much preload but HUGE, fast tucking
