The more I have to squeeze myself into airline seats, the more concerned I get about long-haul flights and deep vein thrombosis.
Why not try the Pocket Gym, which you can use in your seat to help stimulate blood circulation during long periods of inactivity?

Won't I look like a complete wally?
Quite possibly, but this ingenious invention offers a full body work-out and is completely portable. It only weighs 300g has a resistance of up to 5kg and comes with a comprehensive range of 30 exercises.

How does it work?
It comes in five parts in a convenient travel case. You just fit it together to get something that looks and feels a bit like a bicycle pump but offers enough resistance to get the blood going.

What sort of exercises can you do in your airline seat?
There are 20 upper-body, mid-body and lower-body fitness training exercises that you can do in your seat and several others that might be better to try when you reach your destination.

Does it really work?
It's been endorsed by Mark Green, currently medical director of Gatwick Airport and one of the UK's leading experts in aviation medicine.

The Pocket Gym Lite costs £17.95, but is available at airports' tax-free stores for £14.95. For more details, call 0800 0720898 or visit www.pocket-gym.com. There are three other Pocket Gyms offering more resistance depending on your fitness requirements.
