Broni McSweeney set up the 20 Week Challenge™ in 2007 when she was a personal trainer.  It was initially trialed with 20 of her own clients before being rolled out by what is now over 100 Personal Trainers, many award winning. The programme has grown every year since it’s inception.

In 2016  the 20 Week Challenge™ was supported by a generous bunch of 64 sponsors,  lots of clever judges, some great regional reps and a small but mighty crew of awesome staff.


The 20 Week Challenge™ supports individuals, events and organisations like Dress For SuccessSaveMart and the Fred Hollows Foundation. If you would like us to support you, your event or your favorite charity please email us the details of how we can help or we’re happy to brainstorm some ideas with you.

Personal thanks

The 20 Week Challenge™ wouldn’t be what it is today without the input and support of people like Jo Kent, Jean Scott, Aron Anderson, Phil Benoit, Kris Tynan, Carol Hides, Matthew Hides, Tarsh Guy, Desra Barron and her hubby Kent, Amanda Armitage, Leanne Thomas, Lyn Walker, Russell Graham, Belinda Edmondston, Jack Black, Tony Curran, Emily Miazga, Michelle Cawley, Bossman, Tim Webster, Mike Catton, Ruth Gordon, Robyn Perkins, Cara Sulieman and a team of awesome PTs.   Big thanks to the Greenwood’s who provided me with home and office for a whole year after the earthquakes and to the owners of Olympus Health & Fitness Centre & Heritage Health Club who always encouraged and supported me to do more in this great industry. They are a constant reminder that we all need people who have confidence in us and are willing to patiently show us the ropes to keep edging forward.
