Members at selected Fitness First clubs across the UK can now try out Jacobs Ladder, a new piece of fitness equipment which is a cross between a vertical treadmill and high-tech climbing frame.

It was developed by Steve Nichols, a former Western New York fitness champion.

Users climb on rungs, like those of a ladder, which descend as they are stepped on. The faster the rungs are climbed, the faster they go. The equipment is self-powered and suitable for both beginners and seasoned exercisers.

The equipment is initially to be trialled at the Fitness First clubs in Poole and Cheltenham, before a decision is made on whether it will be rolled out nationwide.

Derek Crawford, Fitness First's UK fitness director, said: "We want our members to have access to the very latest and most innovative fitness equipment, so we are always looking out for the 'next big thing'.

"Jacobs Ladder is unique and is already causing a stir with members in the areas in which it is being trialled."
