A donation to a Cromwell gym is designed to get hearts pumping.

Central Fitness, in the centre of the Cromwell Mall, is home to the town’s newest defibrillator, thanks to Andrew Tall Electrical.

The electrical business recently donated the automated external defibrillator (AED) unit, worth $3200, to the gym.

An AED is a portable device that analyses the heart’s rhythm and, if necessary, delivers an electric shock to help restore the natural rhythm.

St John states such a device can increase a person’s chances of survival by 44%.

Electrician Andrew Tall said he was inspired to buy the device during a gym training session when he noticed the nearest AED was 400m away at the medical centre.

“It’s [Central Fitness] the sort of place that needs one,” Mr Tall said.

“People are training and putting strain on their bodies.”

Central Fitness owner Jonny Roberts said he was “pretty stoked” when Mr Tall approached him.

“Having guys like Andrew around to do that is pretty cool,” he said.

The 24-hour nature of the gym meant the AED would be accessible outside standard business hours and emergency services also had access to the gym.
