Jonathan N.
Always a student.
“I teach the why, the because, and the intent.”
After almost three decades in patient care, Jonathan began a new chapter in reformer education in 2021. Today, his work brings movement, strength, and coaching together for instructors and boutique studios.
Training across Xformer, Lagree, and Pilates informs his approach. Read his story and full training background.
Meet JonathanWhat is Exercise Strength Core?
Exercise Strength Core (ESC) is Jonathan N.’s reformer education platform for instructors and boutique studios. It brings together studio training, individual coaching, practical class plans, and a separate Premium membership for continued learning.
Can I train with Jonathan individually or as a studio?
Yes. Jonathan offers training for individual instructors and studio teams, in person or virtually. Send a training inquiry with your goals to discuss the format and available dates. An inquiry is not a confirmed booking.
Where can I see an example before joining?
Explore the beginner-friendly routine for an example of ESC class planning, or visit Train with Jonathan to watch public training previews. These are separate from the private Premium lesson library.
Is Premium included with my original ESC training?
Premium is a separate personal subscription. Your original ESC training resources and existing training arrangements remain separate. Visit the membership page for current enrollment availability and pricing when enrollment opens.
Does creating an account give me Premium access?
A free account is your personal sign-in. Premium lessons require an active paid membership or an explicitly granted period of complimentary access. You can manage billing and see your access status from your membership page.
