Why We CrossFit - Jakob Junker, like so many CrossFit-ers, started with a lifetime of sports experience (especially baseball!) - which is why nobody should be surprised when the calm/cool/reserved Jakob decides to turn up the heat during a workout (that competitive edge never actually leaves!). Yet, what's more impressive about Jakob is how he deals with the challenges of injuries and damage his body has endured from decades of sports. He is the quintessential example of proper scaling, dedication to rehab, and teaching his body how to correct long-engrained movement habits. It's not easy, it takes an incredible amount of perseverance, and requires checking the ego at the door, but Jakob will be the first one to tell you how much better his old injuries, his movement patterns, and overall fitness have gotten with proper CrossFit training and coaching. Thank you Jakob, for being an example of a hard-working and responsible athlete both when you're fully healthy AND when you're dealing with injuries.

Better late than never! Huge shoutout to the champions of the 2025 CCF March Madness tournament! Both Regina Marie and Aaron conquered incredibly tough brackets and matchups to cement their victories, with the final matchup concluding on April 26.

For those that don't know, CCF March Madness is an annual in-house event where women and men compete in a bracket-style tournament to decide an ultimate victor. The ladies' workouts in each round are variations using the "Devil's Press" movement, and the men's workouts use the "Man-Maker" movement. The winner gets their name emblazoned on the CCF March Madness trophies, and until next year's tournament, Coefficient CrossFit will hereby refer to devil's presses as "Regina-Presses" and man-makers as "Aaron-Makers".

Don't miss a chance to come workout with these celebrities. Get a high-five, maybe an autograph, and start training your dumbbell workout for next year's tournament!

It was just 2 weeks ago that we hosted the first competition at Coefficient CrossFit, our inaugural Chaos Theory Throwdown - and WOW...what an incredible day it was. Teams of 2 (F/F and M/M) took on five 6-minute workouts separated by 6-minutes of rest between each for an action-packed & high-intensity competition structure where each team was able to finish in less than an hour.

We could not be more grateful to all the athletes, volunteers, and spectators that made for such a fun day. This competition will most DEFINITELY be back for years to come and we are excited to watch it grow within our St.Charles/STL-area CrossFit community.

Check out photos from the event by going to www.ChaosTheoryThrowdown.com

And of course, congrats to the podium finishers in each division! All podium finishers received medals, and first-place in each division received custom engraved Stanley cups to memorialize their victory!

Coefficient can't wait to send more teams to other local comps in the area - Next up, the Back Lot Bout at UnCharted CrossFit!

Our today is a SHOUT OUT
📣📣📣 to all of these members who tackled this MONUMENTAL 🏔️ April challenge!

Coach Sam laid down the gauntlet 🥊 and levied a significant challenge to accumulate 3️⃣0️⃣0️⃣ pull ups in the month of April. Our members DROPPED. THE. HAMMER. 🔨🔨 Not only were they focused on attacking these pull-ups during training, but they absolutely ATTACKED them before AND after training! Y’all should be proud of yourselves 🥰…your community most certainly is! 🙌🏼🤙🏼

Why We CrossFit - Sophie O'Cain brings the HEAT every day she shows up to class. She walks into the gym with a smile and is relatively easy-going and laid-back...that is until she turns on that competitive gear - that's when the FIRE comes out! As a rugby player-turned-coach, Sophie demonstrates the uncanny ability to motivate, inspire, and befriend anyone that crosses her path.

Don't miss the chance to give her a high-five at the gym and workout next to her - she's one of those people that makes everyone around her better!
