OCTOBER FITNESS/HEALTH/LIFESTYLE CHALLENGE! 22 DAYS HARD!
Start: Monday October 5th-7th
End: Monday October 27th - 29th
GOAL: For 22 days learn to suffer, try something different, learn new things, and build mental fortitude and resilience.
They say it takes 21 days to change habits and 66 days to legitimately start a new one. So 22 days is just the start for some but could be world changing for many.
What's in it for you? Go 22 days and WIN A COOL "Being weak sucks! TRAIN accordingly shirt.

HOW TO JOIN THE CHALLENGE?
**must be member
MONDAY October 5th-7th POST YOUR 1ST POST ON THE CROSSFIT 646 APP (SOCIAL FEED) LISTING YOUR PLAN TO ACCOMPLISH THE 5 TASKS BELOW:

You have 22 days and 5 tasks to accomplish daily.

#1 FITNESS: Get 90 minutes of fitness/exercise daily, with some of it being outside!
Ideally, this should be done in two sessions. You could do a 30-minute walk in the morning and a 60-minute CrossFit class, or you could come early to class for a walk or run and stay after for extra credit. As long as you get 90 minutes, with some of it outside... CHECK THE BOX!
#2 NUTRITION: Whole food dieat (strict) with no sugar! CROSSFIT SAYS IT BEST! "EAT MEAT AND VEGETABLES, NUTS AND SEEDS, SOME FRUIT, LITTLE STARCH AND NO SUGAR, KEEP INTAKE TO LEVELS THAT WILL SUPPORT EXERCISE BUT NOT BODY FAT."
Everyone in the challenge will follow the diet plan above. It is strict whole foods! If it can't be grown, or killed the likelihood is that it is not a whole food.
Anything with unnatural perservatives in them is not a whole food. If something you are eating has a label, check it out and google, "Is gellan gum a whole food?"anwer NO!
NO added Sugar or sugar substitutes on the challenge (This includes stevia, honey, etc.) You can eat as much fruit and vegetables as you would like.
NO Alcholl
Ask any questions you might have on the app's social feed
Watch out for seasonings with added sugars and oils, preservatives, and Natural flavors added into things (these are NOT ALLOWED in the challenge)

#3 DRINK WATER: 0.75 to 1.0 times your Body weight in OZ. Daily.
Example: If you weigh 150 lbs, you should drink 113–150 oz of water daily (this also includes drinks made from water, like coffee or tea).
Error on the higher side based on what you regularly consume.
If you are a good water drinker HIT the 1:1 ratio
If you are a poor water drinker, aim for a 0.75 to 1 ratio
#4 READ 10 pages of educational or self-improvement material daily
Several of you read a lot, but those who struggle should have a plan: educational books for the kids that you can read to them (I have learned so much about animals and nature reading with my kiddos) or something quick and easy to read during breaks (like a little pocket book)
Listening to books will also be allowed.
#5 POST in the APP DAILY
I know this is hard for many to keep up with, but the inspiration from these posts has a domino effect within the gym.
What you do and the hard work you put in can and will inspire someone else, educate them about food, give them ideas, or help them start having FUN with topics that can be stressful for many.
It doesn't have to be selfies; it can be pictures of your food, your dogs your workout board, your water bottle in different locations 🤣, or other random pictures.
If you forget a day just post 2 the next day. You should have 22 posts at the end of 22 days.
NOTES:
You are allowed 2 HICCUPS! meaning you can miss 2 tasks out of the 30 days and still be in the GAME. (you must post about them!)
These HICCUPS are not conscious cheats or an active choice to miss a task but an unconscious miss of a task.
Examples:
Missed a day of reading with the kids (ran out of day)
Accidentally ate a salsa that had sugar or preservative in it with a meal.
Work ran late and I didn't get to the gym

THESE CHALLENGES ARE NOT FOR EVERYONE!
THESE CHALLENGES ARE THE START OF SOMETHING BIGGER (TO CREATE HEATHIER HUMANS AND EDUCATE OUR COMMUNITY OUTSIDE THE GYM)
WE WILL DO 3-4 A YEAR (THEY WILL ALL BE A LITTLE DIFFERENT)
ONE THING WILL REMAIN THE SAME!
THEY WILL BE HARD!

BE SURE YOU ARE MENTALLY READY TO TAKE THIS ON.
IT IS OKAY IF YOUR CURRENT GOALS DON'T ALLIGN WITH THE CHALLENGE.

IF YOU HAVE DONE THE CHALLENGE BEFORE AND WANT TO DO IT AGAIN...YOU CAN

Hey everyone!
Desert City Classic is coming up October 23–25, and they’ve reached out to the local affiliates community for some help.
Their biggest need right now is judges, especially volunteers who can commit to all three
days of competition.
If you’ve been to Desert City before, you know how much goes into making an event like this
happen, and volunteers are a huge part of it. If you’re available that weekend in any of the areas
and would be willing to jump in, they would LOVE to have you!
All three-day volunteers receive:
● A fresh tee every day from Heart & Hook Apparel
● Meals from Nature’s Purpose
● A YETI volunteer water bottle
● A pair of new kicks from inov-8
● A 5.11 patch
Plus, volunteering earns points for [Affiliate Name] in the Desert City Classic Affiliate Cup!
Sign up to volunteer here: Volunteer Sign Up
You don’t have to be an experienced competition judge to get involved. Desert City will provide
the information and direction you need. You just need to be willing to show up and help make
the weekend happen.
If you’ve been thinking about volunteering, this is a great year to do it!

We have several teams and individuals competing.
It's going to be fun.
