Of all the weird and wonderful training trends I've trialled for Men's Health, Electrical Muscle Stimulation (EMS) is surely one of the strangest. The location, for a start, is unusual. My sessions with EPulsive took place in a quiet basement flat off Gloucester Road. With mushroom-coloured walls, cream carpets, floor-to-ceiling mirrors and minimal furniture, it looks more like a show home than a modern fitness space. And then there's the outfit. First, you pop on a slimfit black Bodytec top and shorts. Over that, you slip on what looks like a police vest with multiple wire attachments - the inside dampened with water - along with black bands for your arms, quads and glutes. Once you've gone the full Tron, your outfit is then connected to a control device, via which your personal trainer can "turn up" specific muscles - stimulating them with a mild electrical current to force them to contract rapidly. Your PT is the puppet master and you are his or her human toy.
