I go to Goodlife and they are running the Goodlife challenge at the moment. There are 2 options with this.
1. Testing strength/fitness and trying to improve on this. There are people constantly filming themselves at the gym which I assume is uploaded somewhere to verify lifts.
2. Body transformation challenge. I think this is a harder challenge it's training and diet based, where the first option is purely focused on training.
Seeing I was doing the Max's Challenge this year, the Goodlife Challenge started around the same time (2 weeks after), so I signed up to it as well knowing I was going to make a significant change to my body. By the time the Goodlife registrations opened, I had already lost about 3kg, but in photos I look about the same. In hindsight, I probably should have started the Max's Challenge at this weight to give myself a few extra weeks to lean up even more.
Based on what I'm seeing in my gym, no one else is coming close to taking the transformation challenge as seriously as me. I'm probably going to win it.
