Insane Athlete

I love the experience of a smaller, independent gym. The owner, David, & trainers are experts and welcoming. The classes are challenging and fun and I know that if I show up, I'll get a great workout. I have noticed a difference in my body and I'm excited to keep it up. Outside of the gym I'm noticing that my running is improving.  I've shaved almost a minute off my mile since I started training with David, even though that wasn't something I was specifically training for. When I broke my arm, I was so bummed that I wouldn't be able to work out.  But David encouraged me to go to class and modified my workouts.   My Ortho Dr. & Physical therapist were amazed how quickly I healed.   The Dr told me that being active promotes blood flow and speeds up healing.  It worked, I only missed a week from the gym and could put weight on my arm after 4 months!  David's mission is to bring together a community of healthy and happy people through fitness. He and his team train in a personalized way that allows every person to be in their best shape because they believe that everyone can be an athlete.I personally believe that the owner of a gym is a huge reflection on the gym and its direction. With David's friendly demeanor, knowledge of physical fitness, and ambition to take the gym to the next level to further the quality of lives through diet and physical movement. More...

David is a lovely fitness trainer who welcomes all levels. He knows how to provide modifications when needed and also knows when to challenge people to take them to the next level. I'm just a girl trying to get her first pull-up, and I'm definitely making progress! I love the variation in exercises that David provides and I genuinely look forward to my workouts at Insane Athlete! More...

I like that classes are small. It makes the experience much more personal, which is important for someone like myself who becomes a bit overwhelmed around so many people! Classes are challenging and David is great at upgrading or downgrading exercises as needed, therefore his classes can be attended by almost anyone and everyone! Looking forward to the grand opening.

Been to few bootcamp sin SF , but this was my first time going to one in Marin, and I'm glad that I chose Insane Athlete. I went there with a friend around 11:20 am on a Sunday, and David was already there with few people , getting ready to start the session at 11:30 . He charged me only $10, and gave us a small discount for my friend, and charged him only $8. In the past , I had minor IT-band syndrome , and after mentioning that to David, he showed extreme knowledge of the human body, and explained to me exactly what exercise I should, and shouldn't  do. The workout was intense and my body felt sore then next day , which logically is I great result from the hour long workout we had ;)Thank you David, and keep doing what you do, because you are really good at it !
