Real client result
What eight weeks can change
After the 8 weeks I'm down to 79.3kg, which means I've lost 9.6kg. I've also lost about 10cm off my waist and my BMI is back in a normal range. Now I feel way more in control of my eating and my health. Cheers boys!
I weighed in at 109.8kg and got down to 99.5kg, the first time I'd been under 100 in 5 years. I found the food great and wasn't too hungry most of the time.
The challenge has been a good way to get back into a routine with training and eating. It made me realise how many calories I was consuming through alcohol and food on the go. Down to about 75.5kg and feeling great.
