Challenge FAQ

Challenge sales close October 3rd at 5p EST. Uncoached spots are unlimited and will be available for sign ups until the very last minute. However, coached spots are limited and may fill up before the official sign-up deadline.

Absolutely! To request a coach, please enter their Coach Code in the app that they used to refer you. This is always the coach's name followed by 21 (ex. KATY21).

Coach Codes are referral codes given out by coaches so that our previous #FBKFitFam challenge participants can continue working with a coach that they have worked with on a past challenge. If you do not have a coach code, your coach will be assigned at random. All of our coaches are knowledgeable professionals who were hand-selected by Katy and are ready to help you reach your goals!

Please email us at if you’d like to request changing your coach.

Whether you’re looking to lose weight or gain muscle, challenges can suit your needs as long as you stick to the program and properly track your macros.

If you're looking to build more muscle, try to stick with low to moderate intensity cardio. Keeping cardio at a minimum of 1-2x/week will help you get all the cardiovascular benefits without burning up the calories your body needs to gain muscle. If you're looking to lose weight, aim for no less than 3 cardio sessions per week, and consider moderate to high intensity cardio.

LOW INTENSITY: Walking or easy pedaling on a spin bike for at least 30 minutes.

MODERATE INTENSITY: Incline walking on a treadmill, stairmaster, bike with higher resistance, elliptical/arc trainer for 20-30 minutes.

HIIT: Spin bike, treadmill, outdoor sprints - bursts of all out maximum effort for short intervals (15-20 seconds) with rest/rest walk periods between bursts until heart rate settles to a normal pace. 5-10 sprint intervals based on experience level. Limit HIIT to 3x per week and space sessions out as these are more taxing on the body and are harder to recover from.

Select "lose weight" if you'd like to lose pounds, and "gain muscle" if you'd like to focus on building muscle.

You'll need a resistance band set, a glute band, some sliders and some weights. Grab a glute band right here on our Gear page!

If you entered your macro information in the app and need to adjust the information you entered, you can recalculate them under the nutrition tab in the app.

We actually do not recommend a keto diet when doing one of our strength training programs unless your doctor or nutritionist has recommended it for you. Our macro calculator suggests an appropriate amount of carbs that will support your goals. The workouts require a lot of energy, and a sufficient carb intake is highly recommended to get the most out of your workouts!

Each Saturday, check-ins open at 11AM (EST) and you will be able to check in throughout the weekend. Please answer the seven check in questions and be sure to include any vital information that may affect your macros such as being pregnant, breastfeeding, or any important modifications your coach should be aware of. 

Yes, you will check in once weekly, however, your coach may follow up with additional information as needed throughout the week.

You'll submit progress photos inside the app during each week's check-in. You'll submit your final transformation photos through the last check-in!

If you previously logged into the FIT By Katy app using your Instagram account, you will now be prompted to provide your phone number. This is due to a recent Instagram update that no longer allows users the ability to log into other apps using their Instagram account. Unfortunately, it's something we don't have control over.

If this change temporarily impacted your ability to log in or caused purchased programs to disappear from your account, rest assured that everything you have previously purchased is being restored and will appear in the app.

If you have any issues unlocking your programs, please reach out to
