Testimonials

What our clients have to say...

"I've just finished Sean's online course, and it's exceptional! It summarizes everything you need to understand and master the basics of intensity prescription."

Mathieu

Sports Scientist

"First, numbers, +20 watts on the 20-minute BikeErg. Level sensations, mentally much stronger. For CrossFit®️, much more speed and gas, transitions are shorter thanks to faster bpm coming down and increased lactic 'resistance'. A much more effective recovery with this famous zone 2 post-session and in active recovery session. If I had to summarize, better performance, improved recovery, and reduced transitions…. Anyway, what are you waiting for to start ;)"

Alex

Crossfit® Athlete & Coach

"I did some Wingate work with Sean during the spring of 2022. This work not only made me progress on the BikeErg (+150W on sprints, better tolerance on repeated sprints) but especially in the METCONs. Indeed, I found an excellent transfer on short efforts (Fran type), on the ability to accelerate during an effort and on my ability to switch from one modality to another during an intense effort. I can't recommend it enough!"
