Meet Karlen Thyne

Premier Personal Trainer & Bodybuilding Coach

No matter what challenge you face or what goal you set, Karlen's philosophy is simple: there is always a way.

After fleeing Nicaragua in 1982 with his mom and his brothers due to political unrest, Karlen grew up in Costa Ria. At age 16, he discovered his passion for health and fitness. With resources limited, Karlen got creative by using paint cans, milk jugs, concrete blocks, and random metal bars to build muscle and tenacity. Valuable life lessons emerged: use the bare minimum to get the maximum results.

After 20 years of coaching clients, winning multiple bodybuilding awards, and receiving specialized trainings, today Karlen is co-owner and head trainer at Dynamic Natural Advantage. Located in the Upper Valley in White River Junction, VT, it's a long way from the tropical fruit trees in Central America but right where he wants to be.

Karlen designs custom training programs for new athletes and elite competitors alike, offering in-person training sessions at DNA or at a client's home gym, or through remote online options. Over the years, he has developed sport-specific training programs for youths and adults and is obsessed with helping each individual achieve his or her very best, regardless of what limitations may exist. There is always a way.
