Why Work With a Trainer, and
Why Japheth Specifically?

Most people don’t need more fitness information. In fact, most are swimming in so much health and fitness advice that they experience paralysis, they just dont know what to believe or what to do. They need a plan they can trust, a plan that incorporates accountability, consistency, and expert guidance tailored to their goals. No guesswork, no decision fatigue, just a clear plan and reliable guidance in a format that works with your life whether you are right here in Puerto Vallarta or anywhere else in the world.

Jai has been working in the wellness industry since 2018 and is a Certified Personal Trainer, Corrective Exercise Specialist, Nutrition Coach, he holds the E-RYT500 designation from Yoga Alliance with over 4000 teaching hours, and is currently studying with the National Association of Sports Medicine for an additional specialization in Senior Fitness.

I combine evidence-based coaching, meticulous attention to detail, a genuine investment in my clients’ success and I use a proprietary software system for leveraging your training data to optimize guidance in each session. This approach deliveres measurable results you can see and feel. Working together, your efforts will result in far more reward than would be attainable from going it alone. Its a no-brainer.
