What You Can Achieve
Bikini, Booty, Shred
During this challenge, I was able to push myself not only in the gym but mentally with discipline. This challenge increased my upper body strength and has made me fall in love with the gym again. I was able to see my body transform with the workouts designed and guided nutrition and will definitely use this beyond the 6 weeks.
- Ruth (Sculpt)
My biggest accomplishment from this challenge was having more energy to play with my daughter. I trained 6 days a week and completed 100% of the workouts. My biggest advice to anyone starting their fitness journey is that you first need to learn how to listen to your body to find out what it is telling you it needs.
- Cindy R. (Build)
I’ve done challenges on and off for years, but this is by far the most consistent I’ve been for a whole challenge... I’ve lost around 6kg, but the cm and progress pics are where you truly see your progress! It’s amazing the difference I’m seeing in every aspect of life too. From mindset and mental health, to energy levels and having old clothes fit.
- Jessica (Burn Round 2)
This isn’t my first challenge, and I came into it with a more settled, long-term outlook as opposed to my previous ‘all or nothing’ attitude. As a mum of 4 who had had a mid-challenge holiday AND topped it off with being sick - keeping a steady mindset about it all is something I’m proud of myself for. I love my fitness journey & it’s ALL thanks to being part of this incredible community!
- Emilee (Sculpt, Round 1)
100% would recommend! This challenge has been amazing and the perfect level (was achievable but just enough of a challenge to push me!) the app is easy to use and follow! Can’t wait for the next one
- India (Build)
I made a commitment that I would look after myself better and invest in my health, as a mother of 4 beautiful boys over the last 10 years I have dedicated my life to raising my children but now it was time for me to put myself first and invest in my health. I took a leap of Faith to do the challenge and it was scary but I was committed to my growth and change. RESULTS: Loss 7kgs and loss 85cm ✊🏽
