In order to keep himself in peak physical condition, it is the law that a man must not drink fifteen pints each night of the weekend and munch exclusively on kebabs on Sunday. Sad as this revelation may seem, there are plus points.

Should you choose to live the life of a serial hedonist, you can keep yourself trim by regular exercise. And that doesn't necessarily mean donning a pastel headband and limping round the block a couple of times before collapsing in a heap in your front garden.

No, we have a solution that allows you to break a sweat in the confines of your own home, meaning you can face the neighbours and still keep drinking just a little too much beer at the weekend. The Powerbar attaches to your doorframe like a normal chin up bar but, unlike a normal bar, it has no screw fixings. Instead a cantilever takes a portion of your weight, so you won't bring down half your masonry each time you do a pull up.

This really is the king of exercise bars and because you don't have to screw it into your door frame, it easy to pack away, allowing you 'plausible deniability' as the Americans say. 'No, no, I'm naturally ripped...' Yeah right.
