Although Interfusion Fitness was founded in 2016, the seed was planted long before.  The seed was a simple concept -assemble high-quality fitness instructors from a wide variety of fitness disciplines, and put them all under one roof.  We knew we couldn't be the only fitness enthusiasts who preferred variety in our fitness lives.  Sometimes we favored circuit training, sometimes yoga, sometimes a muscle-building weight-lifting class, sometimes a heart-pounding cardio dance class, or sometimes a technical dance class.  Other times we found ourselves in the mood for a chilled-out stretch class, or high-intensity interval training, or a barre class.  In other words, we love cross training…the original definition of cross training - training through a broad swath of fitness favorites.  However, the main obstacle to satisfying our craving for cross training was driving all over town to do so.  To eliminate that obstacle, we created Interfusion Fitness.

At Interfusion Fitness, variety is now found under one roof.  With three studios set within 4,200 square feet of space, and a highly-skilled, well-trained, friendly and enthusiastic staff of fitness professionals, variety is now as simple as walking out of one studio and into another, or even staying put in the same studio as the classes switch over.  

At Interfusion Fitness we bring the best to you:  sports-inspired fitness training designed and delivered to you by world-class, former professional athletes; movement classes by professional dancers and choreographers; a variety of yoga forms from top-notch practitioners; and other dedicated veterans of the fitness industry, as well as varying styles of personal training.  Besides creating and effective and enjoyable workouts, our main focus is on strength and overall health, with a heavy emphasis on proper form and technique.  Safety first.  We believe getting fit is a senseless process if you continue to get injured during the process. 

‘Fitness for All of You’ is not just our tagline, it’s our world.  It’s the way we want you to feel each time you walk through the doors - As IF Interfusion Fitness was created for you.  Because it was.  It was conceived and built as a fitness destination where people of all shapes, sizes, fitness levels, genders and backgrounds, can feel comfortable getting their fitness on.  It’s a judgment-free zone (yes, we even have No Negative Self-Talk ‘swear jars’) where strangers effortlessly become friends, as they connect over fitness and other similar interests.

It’s no secret we wanted Interfusion Fitness to be different.  When you first enter Interfusion Fitness, you will notice a difference.  A different feel.  A different vibe.  A different moxie.  You will immediately absorb the energy of the midnight purple floors, and realize you’re out of the box.  With its welcoming reception area, snacks, drinks, and free WiFi, Interfusion Fitness is more than just a great place to work out.  It’s a great place to hang out.

We hope to see you soon!

Kelsey is an Atlanta based yoga teacher and Georgia Tech graduate (B.S. Psychology). For nearly twenty years, Kelsey was a classically trained ballet dancer until an injury ended her professional dance career. Having begun dance at the age of three, Kelsey’s relationship with movement has always been an integral part of her life and it is what ultimately led her to explore yoga. When Kelsey first began her practice, she was immediately drawn to the transformative powers of yoga. After a significant personal trauma, Kelsey was able to find stillness and acceptance through her personal practice. She began living with less resistance and learned how to appreciate the present moment. Kelsey enjoys sharing her love of yoga with others and holds a 200 hour level Yoga Alliance Certification (RYT-200) through Decatur Yoga and Pilates under the instruction of Joe Palese.

Kelsey’s classes focus on alignment, introspection, and healing. Kelsey creates a comforting and playful environment in each of her classes, where every student is free from both judgment and expectation. Every body is a yoga body and Kelsey aims to create fully accessible, all-inclusive yoga classes. From beginners to experienced yoga practitioners, Kelsey meets students where they are and helps them safely discover their body’s unique potential. She encourages her students to listen to their body’s emotional, physical, and spiritual needs as they explore and learn their edges. Kelsey loves to make people laugh and draws on this ability to create a lighthearted and supportive space for every student. Kelsey empowers every student to take their yoga practice deeper into their lives both on and off the mat. Her classes will leave you with an enormous smile and a greater sense of love and compassion for yourself and others.

James Hedges

Fitness Instructor

James, a Georgia native, entered the fitness world in college seeking to make some healthier life choices. As he spent more time being active and learning about fitness, he gradually fell in love with the routine and structure that came along with athletic training. At first his primary focus was strength/athletic training, aiming to stay functionally strong in order to enjoy sports recreationally in his spare time (and there was also a small desire to work on aesthetics as well). But following an ACL injury while playing rugby and the reconstruction surgery, James quickly learned the importance of a balanced and holistic mindset when it comes to training in order to keep the body as healthy as possible. For James, working out is a celebration of what our bodies can do and a fitness routine should always embody that mindset. James has been teaching HIIT classes in some capacity for just under two years and loves meeting up with his classes and joining them in a good workout. He is always interested in changing up a regiment to try new techniques and incorporate various fitness disciplines in his workouts and classes. Community is a foundational aspect to all people and for James fitness classes are just one of the places to build community with friends. 

James has a Master of Divinity from McAfee School of Theology and is preparing to start and Master’s of Theology program at Columbia Theological Seminary next fall. But James is even more excited for July 29th,2017 when he will be marrying his wonderful fiancé and best friend, Cora. James and Cora spend most of their free time playing with their two dogs or enjoying Atlanta’s best tacos and margaritas.
