our story

When Karen and Sam mixed their concept and passion with guidance and expertise from celebrity trainer Jillian Michaels, TRX founder Randy Hetrick and fitness expert Obi Obadike, Fuse45 was born.

Karen and Sam are a mother and daughter team who have been exercising and inventing new workouts together for over a decade. Their dedication to healthy living and fitness fuels their lives and they want it to fuel yours too.

Since Sam was in college, she and Karen had a dream to open a studio together. It was only a matter of developing the right concept. They tried every class from New York City to Los Angeles, from London to South America. What was missing for them was a class that was both high intensity and low impact. This perfect fusion is hard to develop, but is key for sustainability. Always up for a challenge, they knew what they needed to create.

With Karen’s professional fitness background and Sam’s business experience, the ladies had the right combination of tools to develop the most perfect workout. When Karen and Sam mixed their concept and passion with guidance and expertise from celebrity trainer Jillian Michaels, TRX founder Randy Hetrick and fitness expert Obi Obadike, Fuse45 was born.

Karen and Sam have a mission to show you that working out is an opportunity to relieve stress, build self-esteem, find balance, and improve both mental and physical health. Fuse45 is not just a workout. It’s a community. When you sweat together, you learn how to share, admire, lead, follow and ultimately reach higher.

I am a physician who was hitting my gym pretty hard 5-6 days a week. I thought I had designed a pretty good workout. My wife was raving about Fuse45 and got me to try a class. WOW, what an upgrade! I dropped 12 pounds in 6 weeks. Even better, Fuse45 is absolutely the second-most fun you can have getting hot and sweaty as a couple!
