About Karin

Karin Fantus has been a music student for as long as she can remember, which eventually led her to an Apply Music degree (Voice) from Boston University.


After college, Karin set her sights on journalism, and became a successful TV news producer in NYC.


She worked for ABC/NBC/CBS, then helped launch daytime TV talk and magazine programs in national syndication.

For decades, Karin has studied many fitness disciplines, especially what's popular among  musicians: Gyrotonic, Yoga, Rolfing, Massage, Meditation, etc.  Of all of them, The Pilates Method and The M.E.L.T. Method had the most to offer her, so she took time out to become a Certified Instructor of both. Now she had the experience and know-how to strengthen, lengthen, decompress, coordinate and balance her not-so-young body... so much so, that 20 years later, her full-body strength, flexibility, freedom of movement, etc., continue to improve.

In 2002, Karin opened her own studio, where she developed and taught her unique exercise system, to coax clients' bodies back toward youthful freedom of movement, joint mobility and an upright sprine.


Key to her clients' success, is Karin's distinctive teaching techniques: by applying the body's own logic  (e.g. awareness of the nervous system's connections to mind and body) to bring clients back toward using their bodies according to laws of biomechanics... in other words, with the least amount of effort...


APPLIED BODY LOGIC (ABL) is a unique exercise system, designed to build awareness of how every part of the body is connected to every other part of the body... and... to teach how deep core muscles initiate our movements, while maintaining a relaxed, supportive posture.


Applying ABL requires:

  • understanding that movement becomes movement when the brain says so.

  • full-body awareness to distinguish habitual, faulty movements - from newly re-patterned, more efficient movements.

  • focus on precisely how exercises are done, and less on the exercises themselves.

  • coachable clients, committed to making progress.

The ABL exercises are subtle, to the extent that new clients often feel they're not doing much. By the end of a session, they're relaxed, then surprised to experience how centered they've become.

Sessions rapidly get progressively harder (and more rewarding), session to session.


For five years, Karin taught group Pilates and ABL classes at AFM Local 802 in Greater New York. Participants were mid-career musicians, at risk for career-shortening overuse injuries from years of incessant practice, life on the road and too many hours in cramped orchestra pits.

During this time, Karin’s work with Opera singers led her back to renewing her own studies in voice and music theory, and she rediscovered the joy of singing in small ensembles.  Then, fortuitously...


Peter Mark moved in, just down the hall from Karin's apartment at The Ansonia.

Karin and Peter soon began swapping professional services... an ABL session = a voice coaching session. Instantly, they realized they both applied the same logical, underlying principles in their teaching, aiming to instill a lasting ability to use singers' full bodies (including the voice!) with maximum ease, strength, freedom and self-expression.

This became the basis for co-leading their first workshops, starting in 2019:
