Sarah Smith, who leads the programme at the Basingstoke Aquadrome, began delivering the sessions in June 2015.
The classes are designed to support individuals recovering from cardiac incidents as they return to physical activity in a safe and structured environment.

He said: “I like to think of Sarah as a friend as much as a trainer. She’s been fantastic with me.
“She finds all your idiosyncrasies and works with you to come up with a plan that suits you.
“Coming here has been great for my mental and physical health.
“Congratulations Sarah on hitting your big anniversary. You’re a credit to the centre.”
Ted, another regular, said the sessions help him start his day with energy.
He said: “After coming to the gym, I really feel full of beans.”
Dr Andrew Bishop, consultant cardiologist and chief medical officer, attended an anniversary event for the centre.
He said: “There is no better way to get and stay fit after heart treatment than to be in their regular classes.”
