Oss Life’s founder, David Beltram, wants to bring a new lifestyle to New York City. The central goal of this new lifestyle: eliminate three great stresses from as many New Yorkers as possible. The Oss Life team will eliminate financial, nutritional, and physical fitness stresses for any New Yorker ready to push their lifestyle.

Meet the Business Owner

David B.

Business Owner

I am a fitness enthusiast, who loves all things science, exercise, and food related. I have a phenomenal relationship with food, finances, and my own physical and mental health. It is my dream to share these great relationships with as many clients as possible.

I hold degrees in biochemistry and psychology, and numerous certifications from the International Sports Science Association (ISSA) and ACE.

When I’m not working with a client on fitness or life consulting, you can find me reading a Stephen King novel in Battery Park, exploring Prospect Park with my dog Arya, (yes named after the GOT character), or exercising outdoors in Central Park. Basically, I love New York City parks !

I am always happy to run a race with a client. Whether it is a 5k, half marathon, tough mudder, or any other awesome race for a great cause, if you want a race mate let me know.

David does a great job keeping me motivated, and giving me an actual idea of how to get the most out of going to the gym. I’m a fairly active person, but I always found going to the gym to be boring and a chore. With David, I’m actually excited to work out.

David is knowledgeable, thoughtful, and is a hell of a cool guy. Aside from being extremely qualified, he pays attention and is mindful of my strengths and weaknesses to the point where he knows exactly how far I can push myself at any given time. In addition, he has given me tailored advice for me to achieve my fitness goals. While I have just started working with him, I anticipate using his expertise and experience indefinitely.

David Beltram is by far the best Personal Trainer I have ever been to and I have been to many over the years! He has transformed me in ways no-​one else has been able to. He is so focused, caring and dedicated to his clients that it becomes not just a tremendous physical experience but a spiritual one as well.
I detest working out but I so look forward to every session with David. He structures it in such a way that the time just flies by and I ALWAYS feel transformed after every session. It amazes me how just one session can make me feel new again.
He is extremely knowledgable, experienced and supportive in all aspects of health and nutrition. I credit him for getting me off of sugar and changing my eating habits significantly!
He is a dedicated professional, mentoring and training others. I have met many of his staff and they are all terrific! Give yourself a gift and experience Oss Life training for yourself and you will see how unique David and his team’s approach is.

David has been my personal trainer for almost two years. I am 69 year old and needed a trainer who would tailor the training to my specific needs. The first year I was training for a trip to Base Camp Everest and David designed a full body program focusing on my legs and stamina. My current goal is to build upper body strength and he has designed a program to help me achieve that goal. In addition, at 69 my body has certain limitations and David continuously adjusts my workouts with those limitations in mind. I recommend him unconditionally.

David is an incredible trainer. I’ve been working with him for nearly two years now. First off, David is the consummate pro. He takes a wholistic approach to your training. While you may only work with him in the gym, he understands that the path to achieving goals extends beyond those walls. He helped me change what I ate, a change that kickstarted dramatic improvement in my health. Next, David listens to your needs. No two people are identical and no person’s fitness goals are static. As your goals evolve, David crafts a workout régime that helps you build towards said objectives. Finally, David makes working out extremely fun. His approachable demeanor and positive attitude are infectious and help you push your limits. I highly recommend David for people of all ages and abilities. If you commit to your health, David will commit to you.

I’m not a fitness training enthusiast and my previous experience with trainers was mediocre at best. Then I embarked on a few weeks of training with David Beltram in hopes of resolving a couple of issues. For the first time ever, I felt that a trainer was actually listening to me and carefully assessing my needs and mindset. He devised a program that was demanding, realistic and almost instantly effective. This was totally different from the occasional one-​size-​fits-​all sort of training I’d gotten at commercial gyms, where making you feel bad about yourself is the key to hooking you as a client. David is the opposite sort of trainer, an enthusiast, who emphasizes everything you’re doing right. He’s a terrific motivator. He’s also a devoted teacher, checking in on you regularly to make sure you’ve got it right.

David has been a fantastic addition to my health. His responsible, safe and knowledgable approach has motivated me to reach fitness levels I didn’t know I had. And more than that, consistently keeping that level over a long term period. I would recommend him and the team to anybody looking for professional trainers

David? How to describe my workouts with David? Life changing. Challenging. Therapeutic. I have tried other personal trainers at Crunch and Equinox and I wasn’t finding any success. I always felt rushed and unimportant. The trainers didn’t really focus on my needs. They were more concerned with finding new clients or texting on their cell. I have been working out with David for over 7 months (longest trainer relationship!) and that just isn’t the case with him. I have seen improvements in my overall strength, endurance, and health. David takes the time to listen to your health concerns and personal goals and helps devise a plan for you meet them. David is so effective that my boyfriend and I even started training with David once a week on top of my personal sessions. I always feel accomplished when a session is complete. I strongly suggest trying a workout with David!

David is an exceptional trainer. If you’re evaluating Oss Life, I highly encourage you to book a first session and see for yourself.
For starters, David is so calm and respectful. He pushes me in a way that is encouraging and not intimidating. He’s enjoyable to spend an hour with and is just so incredibly intelligent. This isn’t a person who took a course online or at a local chain gym and calls himself a trainer. David studied science, and it shows in how he frames his workouts and his thinking.
When it comes to the workouts, God he kills me – in a good way of course. It’s amazing how much ass he can kick in an hour. He uses our time together efficiently and provides me plans for when I’m working out on my own. I’ve only been working with him for a short time and the difference in how I look and feel is incredible. For the first time, I really feel like I’m getting my money’s worth when it comes to exercise. And speaking of money… it’s quite affordable compared to other training options. Let’s just say I’ve tried almost everything, whether training or memberships at Physique, Exhale, etc.
I can’t say enough nice things about David and his team. Don’t waste your time and money getting assigned to a random trainer at the gym you frequent. Pair up with a true fitness professional like David and you won’t be disappointed.

Oss Life is simply the best personal training program ever. Far more than just a physical training program, Oss Life’s overall physical, mental and nutritional approach has fundamentally changed my overall health and positive wellbeing. I have been working with David from Oss Life for the past 18 months and am in the fittest and most positive mental shape that I have ever been in. More than that, I feel 10 years younger and have lost 20 lbs. David’s calm, personal approach is as much life coaching as it is personal training. I see him 3 – 5 times per week and really regret when I have to miss a day. I look good, feel great and generally have the most positive outlook on life that I’ve ever had. Highly recommend!
