After having her first child Destini, who is now 10, she struggled to meet the demands of being a mum.
On top of that, she was made redundant from her job while on maternity leave, suffered a miscarriage during her second pregnancy and weighed more than 90kg at her peak as she dealt with personal issues.
In 2009, after discovering group fitness and allocating �a little me time� to her day, she went through a 42kg body transformation.
The 32-year-old now juggles running a business and being a mum.
�It�s hard work,� she said. �But having your own business gives you a degree of flexibility�
She said being made redundant was tough at the time, but it worked out well in the long run.
�It turned out to be the best thing that ever happened to me,� she said.
Ms Quinn started doing exercise for just half an hour a day, then she began working out a few days a week and got right into fitness.
She now runs her own personal training business called Earn the Burn, which has more than 800 likes on Facebook after only one year of operation. Ms Quinn is also trying to raise $5000 for Telethon by holding a Mega Metafit event on October 10, at 2pm, in Southern River.
