Five of the best heart monitors

A heart-rate monitor can be handy, whether you are training for a big race, just want to improve your fitness or need to check your pulse regularly due to a medical condition.

Monitors usually look like a watch and measure the pulse either at the wrist or connect wirelessly to a strap worn around the chest for a more accurate reading.
