    About Anna Kestler

    Online personal trainer

    Hi Friends, I’m Anna – I’m ecstatic you found yourself here and if you're anything like me, I believe it’s meant to be. I’d love for you to think of me as not only your personal trainer, but your support system when you're feeling stuck or need a push. I have your back! With a serious passion for anything that keeps my mind and body active, my fitness footprint was ingrained from my formative years growing up in a family of athletes. As the youngest of 3 very competitive collegiate basketball players, I quickly realized the power of consistency through my training which ignited a confidence from within. It propelled me to achieve certifications in yoga, personal training and nutrition + open a fitness studio alongside my Sister in our hometown of Pittsburgh, PA back in 2017. Fast forward to today, my love for movement lead me to sunny CA, a place where I can truly soak up all of the coastal outdoor activities while teaching in-studio, 1-on-1 & virtually. I move my body every single day but I don’t believe in restricting yourself. My cadence is work out hard 5 days a week and do moderate lifestyle movement the other 2 days, like walking on the beach or a bike ride. Your girl also enjoys the nightlife accompanied by good food, drinks and friends.
