The T-shirt that measures your workout - perhaps?

May 23rd, 2008

So when you’re at the gym, what tells you when you’re really stretching your performance, going for the burn, pushing the envelope? Well, according to Jon Gilman, who’s a personal trainer, it’s a T-shirt that measures how much you sweat. 

His Perspirometer is a T-shirt with a triangle printed on the front, with the point downwards.  The widest part of the triangle measures a ‘light workout’, the next level down is a ‘good workout’ and the bottom, narrowest part of the triangle leading to the point is a ‘great workout’. Just below the point is ‘shower time’! The T-shirt is a bit of fun, but shouldn’t be used as a genuine measure of fitness for several reasons: 

• Sweat is partly genetic – you might be a person who just doesn’t generate large volumes of fluid: that doesn’t mean you’re not pushing your body to the limits

• Sweat is also a learned response – fitter people who hydrate regularly, sweat more than unfit people or those who are fit and don’t drink as much fluid: in other words, your body learns to manage on the fluid you give it

• Women sweat differently to men – both different amounts and in a different pattern, so this T-shirt doesn’t measure women’s fitness in any way.
