health and fitness: Is it worth it? TRX

‘You end every session aching and exhausted. You know, in a good way’

What is it? Long strips of canvas with rubber handles at the end – you anchor them to a wall, grasp them by the handles and instantly become fit.

How much does it cost? Chances are your gym has TRX straps somewhere. But home kits are also available; I found one on SportPursuit for about £60.
