Meet the Instructors Behind Your iFIT Pilates Workouts

When you train on a NordicTrack reformer, you are not following a pre-recorded routine from an anonymous voice. You are training with instructors who have spent years, in some cases decades, building a specific point of view on how Pilates should be taught and what it should do for the person doing it.

These nine iFIT Pilates instructors bring different backgrounds to the reformer - and just represent a sample of all the great instructors you will find on iFIT. Some came through professional dance. One came through the US Army. One came through endurance sports. One through physical therapy. What they share is a level of depth and credential that is not incidental to the content they produce. It shows up in how they cue, how they sequence, and how they handle the range of practitioners who show up in a reformer class.

With an iFIT Pro Membership and the NordicTrack Ultra 1 Reformer, you have access to the full library of instructor-led sessions on demand. Here is who is leading them.

Yvette McGaffin

Yvette McGaffin is the Director of iFIT Pilates Product Marketing and the founder of Reform RX. A Pilates authority and functional movement expert with 15 or more years of experience, she created the Reform Method and continues to shape how connected reformer Pilates is taught and structured at iFIT.

"Reformer Pilates is the most complete whole body exercise. It strengthens and conditions your upper body, lower body, and core foundation, for a longer, leaner, more powerful physique. Our instructors will empower and encourage you through every class. The experience and results are like nothing else."

Her sessions span the full spectrum from foundational work through advanced powerhouse training, and her influence runs through the architecture of the iFIT reformer library itself.

Jeni DelPozo

Jeni DelPozo brings 18 years of dance and movement experience to her Pilates teaching. Her approach is athletic: she works on body control, alignment, and building a resilient body capable of peak performance. In her sessions, she focuses on reducing strain through precision rather than through working at lower intensity.

"Teaching on the Ultra 1 is amazing! I love how versatile the reformer is giving me so many options to change up my classes and my own routine as well. The push button spring changes are super easy and everyone can quickly change springs and get to the next exercise. It’s a beautiful reformer that I’m proud to teach and train on."

For practitioners who want to feel technically correct as much as physically challenged, Jeni is a natural fit.

Abe Ahern

Abe Ahern is an Army veteran who traded military intelligence for the reformer. His teaching balances rigorous discipline with elegant technical precision, and his approach helps clients build resilience through intelligent, athletic movement.

That combination of discipline and precision gives his sessions a distinctive character: demanding without being chaotic, technical without being dry.

"The Ultra 1 Reformer has been a pleasure to teach and practice on. The elevated design and efficient function have helped me program movements that feel more elegant and controlled, and the sturdy “spine” helps me teach athletic exercises that are just not possible on other reformers. I love this machine."

Ashley Paulson

Ashley Paulson is an elite endurance athlete and Ironman triathlete who uses Pilates as the ultimate cross-training tool for injury prevention and mental resilience.

That framing matters. Pilates through the lens of an athlete who competes at the extremes of endurance sport is not the same as Pilates approached as a standalone practice. For runners, cyclists, triathletes, or anyone whose primary training is cardio-based, Ashley's sessions offer a specific kind of value: the mobility, stability, and mental focus work that keeps a high-volume body functioning well.

“Teaching on the Ultra 1 Reformer changed everything in the best way. Push-button resistance = no pauses, just smooth, seamless flow from start to finish. It makes every class feel like a vibe– fun, fluid, and totally in the zone. Once you get that kind of flow…you’re HOOKED!”

Kelsey Sheahan

Kelsey Sheahan is a certified Pilates, barre, and pre- and post-natal group fitness instructor. She uses her experience and knowledge to motivate others to reach their fitness goals, and her crossover certifications mean her sessions draw from multiple movement disciplines.

Her pre- and post-natal certification is worth noting specifically. For people training through pregnancy or returning to training after it, Kelsey's programming offers a qualified, informed approach to reformer work that many instructors cannot provide.

Pearl Fu

Pearl Fu focuses on longevity, specifically fitness after 50. In her Pilates classes, she guides practitioners through quick, effective bodyweight exercises designed to support long-term health and function.

That specialisation is increasingly relevant. Reformer Pilates is well suited for this stage of life because it provides resistance and range of motion work without joint loading, and Pearl's programming is built around making that accessible and practical.

Laine Karwoski

Laine Karwoski has always had a passion for movement, from hiking and biking to rowing, running, barre, Pilates, and strength training. She is certified in pre- and post-natal fitness, and her approach ensures that everyone, at any stage of their journey, feels supported and motivated.

Her multi-sport background gives her sessions a grounded, cross-disciplinary quality. She is not a Pilates purist, and for people who train across modalities, that translates well. Her prenatal Pilates strength sessions will leave you feeling challenged and empowered.

Sara Colquhoun

Sara Colquhoun has shared her love for Pilates and dance since 2004. She holds a Diploma of Pilates Instruction, a Diploma of Dance and Performing Arts, and is a certified Master Instructor in Pilates.

Twenty years of teaching and Master Instructor status represent the kind of depth that produces very precise, well-structured programming. Sara brings a classical grounding to her sessions while blending in contemporary movement, and the credentials behind that blend are substantial.

Jacquelyn Umof

Jacquelyn Umof is a certified personal trainer with certificates in mat and reformer Pilates, barre, and Kundalini Yoga. Her workouts focus on helping people heal pain, reduce stress, and love their bodies through easy-to-follow mindful movement.

That focus on healing and stress reduction sets her sessions apart from the more performance-oriented end of the iFIT library. For practitioners coming to Pilates for recovery, pain management, or a more restorative practice, Jacquelyn's approach is specifically designed for those goals.

The Range Is the Point

Whether you’re a competitive athlete using Pilates to get an edge, someone over 50 training for longevity, a new parent navigating post-natal recovery, or a practitioner who wants classical precision from a Master Instructor, there is a body of work in the iFIT library built specifically for where you are.

All are accessible on the NordicTrack Ultra 1 Reformer and the NordicTrack Ultra 1 Reform RX-S with an iFIT Pro Membership. New series are released on a regular schedule throughout the year.
