ABOUT
PERSONAL TRAINER & RUNNING EXPERT
My name is Jérémie Seck, also known as Jay Doesitall. I'm a certified personal trainer, passionate about running, performance and wellbeing. I help runners - from a first 5K to seasoned marathoners - reach their goals and push beyond their limits.
My coaching is built on three pillars: sustainable progress, injury prevention and joy in the effort. I bring this vision into each program, flexible and tailored to every level.
WHY WORK WITH ME?
- Before being a coach, I'm first and foremost passionate about sport and people. I love to connect, exchange, challenge myself, win and above all, share.
- Still active in competition (running, Hyrox, Spartan, etc.), I stay grounded in the reality my athletes face.
- At 40+, my experience shows that you can progress at any age. I adapt to every profile, from beginner to advanced.
- My support goes beyond performance: I also take into account your personal, professional and family constraints, because they are part of real life.
- Together, we build a clear, motivating and tailored roadmap so you can move forward with confidence and results.

MY PARTNERS
I’m grateful that certain brands are willing to support me in my sporting challenges. I make sure to accept partnerships that align with my values and my vision of sport, and that are connected to my athletic project or my lifestyle.
I have been an On ambassador for 4 years and have also been a running and fitness coach for the brand for the past 2 years. I am convinced by its values, its vision of performance, its design, and its inclusive approach.
Powerbar was the first brand to trust me at the very beginning and has supported my sports nutrition for 5 years.
