Hear what John has to say about Exerfly...

"After spending lots of time training with Exerfly flywheel technology and getting to understand the ins and outs (forgive the pun) I can hand on heart say, I really rate this form of resistance training and feel that it has much to offer the strength and conditioning and physiotherapeutic professions. As such, I have accepted a Head of Education role and am very much looking forward to working with Jordan, Nick and the team. I think the education piece will be very important as they push their new and innovative products, such as the motorised “eccentric boost” technology into various markets. There’s lots to do and the course below the first step in this partnership together. Join us in this journey!"

I think a lot of it is such great information for physio’s to either revisit or get introduced to because the science around injury is rapidly catching up and more and more the focus is to restore the key metrics around strength and power.

Having just completed the course “Eccentrics, Concentrics, and Isometrics Unpacked” I can confidently say it’s one of the best short S&C courses I have done. John has packaged his learning modules with an excellent blend of both theory and practical, and I came away with an enhanced knowledge that will immediately impact my strength coaching and programming going forward.

John Cronin's course, "Optimizing Strength and Power - A Connective Tissue Approach" is a science-driven, video-supported, well-organized, and clear course that will help strength and conditioning and physical therapy professionals take their practical application of knowledge to the next level. I will recommend this course, and John's additional "Research Bytes" to those who want to elevate their practice through a thorough understanding of the science and how to transfer that to sport and training applications.
