The Best Personal Trainers in Marin

Every body is different, and most people aren’t going to have great results if they just go straight to the gym and begin pumping iron. A personal trainer can help you learn what’s best for you and help prevent — or recovery from — any injuries. The 2023 readers’ choice Best of the County winner is Heather Leigh Fit For Life (pictured above). For the rest of the Marin Magazine‘s Best of Marin County Personal Trainer picks see below.

Our 2023 Fitness & Sports category sponsor is The Club at Harbor Point.

The Club at Harbor Point: 2023 Best of the County Fitness & Sports

Club at Harbor Point
Providing friendly and professional service in a social resort atmosphere, Harbor Point boasts a clubhouse, restaurant, pool, tennis courts and fitness center. Owner and general manager Patrick Kalinski is part of a family that has owned and operated the club since the 1960s.

What are some fitness trends you’ve liked throughout the years?
Seeing tennis surge again during and after the pandemic was encouraging. Mobility and core strengthening, like pilates, Gyrotonic and yoga continues to grow in popularity.
What was your biggest tennis tournament moment?
Having Andre Agassi and Steffi Graf play on our courts during our Esurance Tennis Classic was magical. Also, having the oldest living Grand Slam Champion in the world, Vic Seixas, as a part of our community is an honor.
What is something you love about the club?
The original plans for the Harbor Point development had a 100 + berth marina, but because this never happened we now have such a beautiful view of the open water, with seals, bat rays, pelicans, egrets and more.
