Come join Gambit Fitness celebrate Mardi Gras with "St. Louis' Least Legitimate CrossFit Competition" but one that will guarantee you lots of fun!

A short, high-intensity competition set in the heart of St. Louis' Soulard Mardi Gras celebration. 5-6 strength and fitness-based events typically around 5 minutes in duration.
The competition takes place from 8AM - 1PM with the party going on until 4PM-ish. As an athlete or spectator, you can enjoy the Mardi Gras parade between events with food and beer included in your ticket price.

This is a partner competition. 3 divisions are available: Scaled, Intermediate and Rx.

Recommendations are simple. If you typically do not Rx your gym WOD, choose "Scaled". If you mostly Rx the gym WOD, except when the weight is very heavy and high-skill choose "Intermediate". If you always Rx your gym's WOD and sometimes choose the Rx+ option when available, choose Rx.

We will be back next week with another amazing company!

Town Hall is now preparing Welcome Kits for new families that are moving into our community.

These new families are looking for a new EVERYTHING!

Town Hall contacts these new families each week as soon as they move into their new home.

These new families will find new places to eat, work out, wash their car......they need a new Hair Salon, Spa, Auto Repair Shop, Optometrist, Dry Cleaner, Pet Groomer, Day Care Facility, Florist, Nail Salon, Pharmacy......you get the idea. They are actively seeking new local businesses and creating new purchasing patterns. They will become someone's next new local, loyal customer.

Town Hall will direct them to you before your competition even knows they are here.

Since our Welcome Kits are exclusive, and we can only accommodate one business per category, I would ask you to kindly let me know if you are interested in being featured in our local Welcome Kits.

I would like to schedule a time when you are expecting me so that I may drop off a sample of our "Welcome Kit" and explain the program in greater detail.

Please reply to this message with your availability or call me at your earliest convenience.

For a faster response, or if you prefer, feel free to text me on my cell which is listed in my signature.

Thanks.

Strength & Conditioning everyday.

We use our “strength” segment of our group classes to get better at moving. Initially it’s lighter weights working technique and then when you’re comfortable with the movement we’re working on that day you start challenging yourself with more resistance each time! Some times people are comfortable day one some still choose to work technique years into training. Both are fine because there’s multiple benefits to the movements we choose, not just strength….. coordination, balance, mobility, stability….

07/04/2022

Happy 4th of July from the CFN crew!! We hope you’re all enjoying your day!! ❤️🤍💙

To celebrate, come try any class for FREE all week!! Message us for more info!

Coach Zac getting the 9am ready for some Barbell weightlifting.

Sn**ch day.
- it can be intimidating at first but our coaches do a great job breaking it down step by step and making sure each athlete is working at their appropriate level with ALL movements.

Sn**ch is a movement that improves full body coordination, shoulder stability/strength/mobility, core strength, leg mobility/stability/strength, and so much more. Even if you aren’t able to throw around “impressive” weight your body thanks you for using the exercise to make it more functional!

**ch day is our favorite!

06/12/2022

Sometimes some of us get a chance to test our fitness in fun completions!

Here is the Nucleus crew full of athletes and spectators from Firebreather this weekend at Capital City CrossFit.

Congrats to the teams who gave their all and thank you to everyone who came to cheer them on, love having the biggest crew at these events!

Big congrats to & for bringing home the Gold in the RX woman division! Great work ladies!!

06/10/2022

We love new faces!

Let the summer weather motivate you to come give us a try.

Group fitness has a long list of benefits!
Our bodies are very similar so our fitness plans can have a very similar foundation… squat, hinge, push, pull, run, jump… Strength train, cardio, mobility…

Top 3 reasons to join Nucleus group CrossFit class.

1) Professionally trained coaches to lead you through 60 minutes of exercising every day. From a general & daily specific warm up, focusing on developing stronger more toned muscles during our strength piece, and making sure you’re doing appropriate movements you are confident with for our daily conditioning/fat burning piece! Along with having our coaches help you learn new things and improving your movement technique for all exercises!

2) Educated & experience goes into writing the daily workouts. Coach Michael Whetstone has been inside a gym for over 25 years. In 2009 he got a degree in Exercise Science from SIU-Carbondale. Certified personal trainer through the National Strength & Conditioning Association. TRX certified. CrossFit Level 1, 2, & CrossFit Sport specific certificate. Masters in Education which helps develop a coaching strategy that layers our classes for all fitness levels from those who never worked out before to professional athletes.

3) Accountability & Motivation through new friendships. Our members become more then just gym members. You’ll have workout buddies looking forward to training with you everyday!
