After having a baby 3 months ago, I knew it was time to head back to Osi. I decided to join the group classes and I couldn't be any happier. The small group instruction allows the classes to be tailored to each person's individual needs. The instructors have been absolutely incredible. Shout out to Molly and Daniel! But most of all, I can't say enough about Osi and her personal care and individualized attention for each member. From her skilled knowledge of form and technique (even from across the room), to her insights on nutrition and habits, have been truly life changing for me. I gain so much energy each day when I walk into the studio. I see the results each day! Thank you for making fitness so much fun and incredibly rejuvenating!

I love this gym, Osi and her team of trainers (Danny especially) are so great. You can tell she’s seriously knowledgable about form and exercises. She works you out in an approachable way, and knows when to push you. Hee exercises are unique and creative always, I’m already seeing such an improvement in my strength!!

I’ve been going to Osi’s for a few weeks now and WOW finally, just what I’ve been looking for! I used to be a member at lifetime (amongst other local places I’ve tried) but found it way too big, the parking for classes stressful, and too many people. I absolutely love the trainers here— shoutout to Molly, David and Osi who I’ve trained with so far— such close attention to form and really effective workouts. Thank you so much for starting this gym Osi! And thank you for capping the classes at 8 people, makes a huge difference! I love the energy I get from working out with other people (so far all my fellow classmates have been badass women) while having the support/safety of a much lower instructor to client ratio.

Osi is the very best. If you’re looking for an expert to help guide your body into the best possible shape and increase your strength, look no further. Osi will encourage you and motivate you to succeed. Her staff are also excellent so no matter who is teaching the class, you’re in great hands. I highly recommend this studio.

I am so excited to have found Osi and her gym! Osi and her team are fantastic trainers with a huge emphasis on form and technique. The group classes are small in size with lots of personal attention and designed to accommodate all levels of strength. I already notice such a difference in the way I look and feel and can't wait to keep working with Osi.

I can not say enough about Osi Bodyfit!! I found Osi by her reviews online. From the moment I walked into her gym I knew it was exactly where I wanted to be to get my body in shape. Not only is Osi and her staff amazing, everyone at the gym is amazing! They all welcome you as if they have known you forever! My big concern about finding a trainer was that I have a hip tear that I was told will need surgery. I was in a lot of pain. Knowing if I built the muscle around it I can avoid the surgery. Expressing my health concerns, Osi was so knowledgeable and willing to get me where I wanted to be! She is really hands on with form and doing everything correctly!!! Let me tell you, my hip has never felt better! I have no pain! On top of my body looking so different in one month! We did pictures the first day, than to see the transformation after a month is incredible! Needless to say I’m addicted to working out with Osi and her team! Her gym is truly the best!!!

Osi is an outstanding personal trainer! She is an expert in teaching proper form, making sure that my workouts are safe and effective.

Osi is absolutely amazing at what she does. She is professional, knowledgeable and caters to exactly what the client needs to not only reach their fitness goals, but sustain a healthier lifestyle. You can feel how genuine and passionate she is in the gym and emphasizes quality over quantity. You definitely get what you pay for and when it seems like you can’t do that extra push up, Osi motivates you until the end and you leave that gym feeling better than when you came in. She is worth it. Thank you Osi!!!
