No, I won't have you eating sardines or training 2x a day.

This challenge is for both men and women - I've written different programs for each of you. For women, we'll be training 3-days per week, hitting our whole body but extra emphasis on glutes, abs and developing that toned hourglass figure. For men, we're going for that superhero look with wide shoulders tapering down to a six pack, with strong legs to match. Men will be training 4x per week in a modified upper-lower split that gives extra upper volume.

The goal is to get shredded, and not in a way that causes misery, but with a lifestyle and habits you can take with you after the challenge ends to stay fit for life. I've kept all workouts under an hour long in both programs.

$101,000 in cash will be split across the best transformations - 1st place will get you $15,000, but even if you get 39th you'll still get $1,000.


If you've been wanting to get fit anyway, this is the time to pull the trigger.

In the best case, you win $15k, and in the worst case, you've taken a step towards improving your body, your mindset, and your health.

Are you ready to see what we can do in six weeks?

Loving this challenge. I feel like it focuses on all the main muscle groups I would want to either grow or define whilst ensuring I get glutes in every weight session which is perfection. Loving the community and overall vibe and support. Im finally starting to see actual definition and results which is incredible. Thanks Austin

This is definitely a good challenge, it targets extra areas in the body that may get missed when doing other workouts. This is a great addition to other workouts like Pilates or Yoga. I can definitely feel the burn.

So far so good! The only suggestion thus far is the ability to uncheck the ‘completed workout’ option. I recognize it was me/user error but it would be nice to have been able to unselect it because I missed data from the actual workout, it only retained the warm up because I clicked it incorrectly/prematurely. Only difficulty I’m having -which is also user responsibility- is making the “Women’s Gym” work with my at home gym setup I have (Speediance Gym Monster). But we’re doing it!
