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.


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

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

What's included
✔️ Workout plan with sets, reps, & demonstration videos for exercises

✔️ Adaptive nutrition guide specific to your body and goals

✔️Shopping list
✔️ Private community with others doing this challenge for support & accountability
✔️ Mobile app to track your progress (iPhone & Android)


✅ 30 day money back guarantee...love the experience or get your money back. You can request a refund directly in the app from your profile!

Personally dont like apps for working out but Austin's workout layout is easy to folliw. There were glitches and couldn't access workout. But I do like the recipes, and the completion celebratory banner at the end of the daily workout. I also like getting feedback and reading comments from others in the program.

So far, everything has been great. My only issue is having to deal with the timer. It’s convenient but it’s also ‘in the way’ so to speak if accuracy is pet peeve of yours. I’m getting used to it. But all in all, great app and great community!

I’m extremely happy with everything about this program! I love the app, all the help it provides to staying on track, it’s giving me purpose so I continue. I’m so happy and I hope Austin does another challenge shortly after this one. Even though it’s only the beginning of week two I already know I’m going to benefit greatly from the structure this program provides and I’ll want it to continue!

I like that there’s at home and gym options as well as warmups and cooldowns. Both the warmups and cooldowns are important and yet most plans don’t include them

Great community support & encouragement. As well as guidance from Austin in the community. I enjoy that there is a lot of room for substitutions since I do not workout in a gym as well as videos showing proper form. It is nice to track reps/weights to see growth & the macro counter is also a great resource in addition to the meal planner in the app

I love everything Austin has programmed for us from the insanely genius macros app he built himself with his nerd knowledge, to the three-day lifting split he designed to get our butts in shape! The women’s gym challenge is a challenge. It is not for the faint of heart lol you will need to buckle up, buttercups… it is for anyone who enjoys pushing their mind and body. Hoping he does this again with Solin.

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.
