A Unified Force of Fitness

We’re big, yes. Over 9,000 square feet to be exact. But we’re far from big box. From climbing ropes to sleds and tires, to rings and pull-up bars, our full-force fitness facility is equipped with a wide range of strength and conditioning stations that are designed to accommodate everyone from fighters to soccer moms.

You + Us A Damn Good Fit


She was named 5280 Magazine’s 2013 Top of the Town Best Personal Trainers. She’s consistently ranked as one of Denver’s top 10 trainers by Denver’s A-List awards. She won her first boxing match by TKO.

To say Tiffany is a big deal is an understatement. She left her career in politics and her position as a board member for the Women’s Campaign School at Yale University to focus on fitness and her clients. And she hasn’t looked back. After training at a big box gym for a few years, Tiffany decided it was time to become her own force of fitness. Her vision was to create a no-frills gym that emphasized training and conditioning, not flexing in front of the mirror or prancing around in tight clothing. No matter your age or fitness ability, at Blunt Force, everyone is equal. It’s not uncommon to see clients, trainers, and fighters sweating side-by-side. But what Tiffany really loves is the camaraderie that happens organically outside the gym. It’s not uncommon to see Blunt Forcers running races together, cheering for the fight team at MMA events, and proudly sporting their Blunt Force gear all over town. Blunt Force is more than just another Denver gym. It’s a fitness lifestyle with an army of loyal followers. Tiffany is the mastermind behind it all. When Tiff isn’t making clients sweat, she’s boxing, running races and traveling the globe searching for the best food trucks.

In the fitness world, some might look at Charlie as an underdog. And that’s perfectly fine for this comeback, come-from-behind-kid.

Charlie had been struggling with his weight since childhood. At the start of his freshman year of college, Charlie weighed 375 pounds. After he graduated, he knew it was time for a change. He started running and working out; by his 25th birthday, Charlie had lost 190 pounds. He left his desk job and began working out at Blunt Force. Since then he’s lost over 7% body fat and put on 40 pounds of muscle. But transforming his physical physique was only part of Charlie’s goal. The other was pursuing a career in personal training. It’s no surprise that Charlie found a way to muscle through his training and come out on top. Charlie brings a real passion to Blunt Force every day, whether it’s through his own workouts or the classes he teaches. He recently became an NASM Certified Personal Trainer and is pumped to be a part of the Blunt Force family. If you have a personal obstacle, like losing weight or getting in shape for a race, Charlie is just the man to have by your side. When he’s not at the gym, which is rare, Charlie loves spending time outdoors. But even then he’s usually hiking, climbing 14ers, or conquering the latest obstacle course race to come through Colorado.

Ian definitely embodies that Rocky mentality found around the gym– “It’s not how hard you can hit, it’s how hard you can get hit and keep moving forward.” In fact, that’s how Ian’s fitness career began.

After being sidelined from a major sport’s injury, Ian went through a long and painful rehab. During his recovery, he quickly discovered that he had a true passion for health and fitness. This ah-ha moment eventually led him to George Washington University where he earned his degree in Exercise Science with a focus in Athletic Training. From here, Ian continued his education as a volunteer at the Walter Reed Naval Medical Center MATC, and as an intern in practice clinics. Eventually Ian ended up in Denver, and luckily at Blunt Force.

Here at the gym, Ian uses a combination of strength training and corrective exercise to improve his clients’ overall quality of life and help increase physical longevity. And when Ian’s not snowboarding, rock climbing or skydiving, he’s putting all his certifications to good use. His current certifications include: USAW Sports Performance Coach (Olympic Lifting), Kettlebell Coach, Trigger Point Therapy, Prenatal and Postpartum Training, Precision Nutrition, Functional Movement Systems FM and ACSM Certified Personal Trainer. To describe Ian as driven would be an understatement.
