"It all started because I knew there had to be a better way."

Conventional fitness ‘wisdom’ promoting five-day-a-week exercise routines left me injured and worn out — as well as my clients.

Sure, they were exercising a lot…but also felt exhausted and had trouble breaking through stubborn body fat plateaus. Sound familiar?

There’s nothing worse than showing up to the gym day after day and not seeing progress.

So, what do you do?

You exercise more….and start to eat less —sending you into a metabolic tailspin where your body is less efficient and stores even more fat!

Or just give up…

I started to develop a new fitness framework backed by science. But I knew gyms and trainers would never implement.

(Hint: when they sell you that “more” is better…it helps their bottom line.)

After years immersed in science and recruiting friends and family to test my protocol —the High Efficiency Fitness methodology was born.

I opened InForm Fitness in 1997— a 300 square-foot basement space with five pieces of used equipment.

In November that year, this ‘radical’ workout was featured on the front page science section of the New York Times.

InForm’s ecstatic, and quickly growing, client base fueled more publicity and a book deal with HarperCollins. In 2003, with my friend Bill Schley, I co-wrote Power of 10: The Once a Week Fitness Revolution. It became a NYT bestseller and I was thrust into the limelight appearing regularly on the local and national media scene.

I would not still be weight training 7 months later if it weren’t for Adam and Inform Fitness. I knew I needed to add weights and strength training to my yoga / racquet sports routine, but I put it off for ages because I hate gyms. Inform offers supportive 1:1 coaching and training that I can easily fold into my week. The workouts are challenging but not insane and the entire vibe is supportive, encouraging, and practical. You are in and out in 30 mins or less. 5 stars!

The proof is in the pudding! After just six weeks @ twice a week, this 78-year-old is way stronger! Jillian at reception and my trainer Jack are welcoming, efficient, and totally professional. They make the whole experience—whether in person or remote—easy and rewarding!

I have been working out with the team at Inform Fitness for many years. I cannot say enough good things about the workout, which is both challenging and extremely efficient from a time perspective and well as the service of their personal trainers. Their Port Washington location is newly renovated and spacious so you don't feel like you are on top of other people while you are working out.

I love this workout and look forward to my 2 days a week for 30 minutes. I feel fit and have more muscle tone that I’ve had in years and…. I do yoga and or Pilates regularly. Inform is fantastic ! Then trainers superb and if your lucky Jillian the manager will give you Netflix recommendations.

I have been training at Inform Fitness for over 10 years now and it has become my home away from home. Everyone here makes you feel so well cared for, from Jillian at the front desk to the trainers and Adam, the owner. Oh and I’ve shaved about two inches off ny waistline thanks to my trainer Jonathan. This is the perfect workout if you don’t have a lot of time to spare as it builds strength and muscle tone. ❤️

Inform gym is for the person who requires individualized training that minimizes the risk of injury while doing weight training. After being diagnosed with rheumatoid arthritis, I needed to find a trainer and gym to help me keep fit. When I first started at Inform, I was skeptical since I was a runner who believed a good sweat indicated a good work out. You might not break a sweat at Inform, but the trainers at Inform really put you through a regimen of weight training designed to increase your strength and overall fitness. I have worked with four different trainers at Inform and all were knowledgeable, articulate and patient. They are also committed to helping their clients achieve their exercise and health goals. A plus is an efficient manager who is a lovely lady who tries to accommodate everyone's schedule.

I started going to Inform Fitness based on a recommendation from a friend. It’s been a few years now and I can’t say enough about Inform and the workout—the staff is knowledgeable and friendly, the workout is efficient and I feel stronger as a result!

Smart, collegial, focused and it's OVER in twenty minutes!!! You still get the muscle soreness from a multi-hour workout but it's concentrated and quick. I do miss the steam rooms of a traditional gym but INFORM fits well into an urban lifestyle. Terrific staff - great vibe.

I really enjoy my workouts at Inform Fitness where I have been going to for over a year! All the trainers are wonderful and Jillian, the manager, is awesome! I workout with the amazing Dan Muhlstock. Since I have been having some back issues , he has tailor made a program for me which is helping to make me stronger. I highly recommend Inform Fitness!

I have been working out at Inform Fitness for almost four years and have trained with Jack Morer for all of this time. I love this gym! The atmosphere of Inform is welcoming and fun, and I truly look forward to going each week. Jill the office manager is wonderful, and Jack is the most incredible trainer. I have several injuries and Jack always finds a way to safely modify the exercises. I have gained strength, endurance, and confidence. I highly recommend this gym for all fitness levels.
