Why Impact?

“We are committed, dedicated professionals offering unwavering positive attitudes that use health & fitness to transform the body, mind, & spirits of our clients.”

Impact MetroWest’s main objective is to motivate, educate, and inspire people to be better than they ever thought they could be. Optimizing performance within the mind, body, and soul.

We pledge to deliver a coaching program that guarantees results-driven workouts built around needs, wants, and desires. Getting people to take massive action on weak links and limiting factors while they train, but also the 165 to 166 hours we are not together. Leaving our mark with purpose, energy, and enthusiasm is the key to our success formula.

We play with passion, live with purpose, and strive to create Impact in the lives of millions.

We believe you should:

  • Care about the work you do.
  • Surround yourself with people who care.
  • Show your team you care about them.
  • Build a team that care about one another.
  • Together show your clients you care about them.

When you care, you try harder, you’re more patient, you’re more curious and understanding, and you’ll learn whatever you need to so that you can help the person you care about. And that’s how we’ve been able to get serious results with thousands of clients from every walk of life for almost two decades.

Discover the Secrets to Weight Loss That Michelle and So Many Other Framingham, Sudbury, and many more MetroWest Residents Have At Impact Metro West

It’s really true…You CAN Lose Weight and Keep it Off FOREVER! And, it really isn’t difficult…once you let me show you how…

Now, for all my skeptical friends out there, let me share this with you first to set your mind at ease and show you how this Metro West weight loss program is different – REALLY DIFFERENT!

Make a Change

How Is It Different?

You mean, other than the fact that IT WORKS? That’s easy. It’s different because…I UNDERSTAND.

Allow me to fully introduce myself and tell you what I mean when I say, “I understand your struggles with weight loss.”

My name is Peter McMahon, and growing up as child and young adult, I struggled with being overweight, deconditioned, and lacking any self-confidence. Throughout these difficult years, my life was a living hell. I didn’t want to go to school, or socialize, and I felt super uncomfortable in my own skin. Worse of all, Athletics (baseball, basketball, and football) which was my passion, suffered from a lack of confidence and mental toughness. Through hard work, discipline, passion, drive, and a tremendous commitment to health/fitness. I developed my mind, body, and spirit which has completely transformed my life. It’s EXTRAordinary. Going into every day bringing the best version of you is what living life is all about.

Now, as we mature(get older) and live our life, we phase in and out(the treadmill of life) of these thoughts of pain, frustration, and distress about not being where we want to be. We want to be fit, strong, sexy, lean and achieve the weight loss that has burdened us for many years. Ultimately, having much more confidence to live that life is worth telling a story about.

So, as you can see, I very much understand the weight loss battle, and I know what it takes to lose weight. I’ve dedicated my life to helping people right here in Framingham, Sudbury, Wellesley, and Natick lose weight and feel great! Now, I want to help YOU lose weight and feel great, too!!

I have been a member at Impact for nine months. I am feeling stronger, with more energy, stamina and overall well-being thanks to Coach Peter, Coach Tiff and Coach Zack! Guidance is always given to enable every client to have good technique of all exercises for optimal benefit, functionality and performance. Accountability is huge at Impact and the Coaches work hard to provide a fun, challenging and effective workout every time that will keep you coming back again and again! I have seen the effects of this program on the tennis court as I’m moving faster, getting to every ball and racking up more winning matches! Coach Peter is very dedicated, knowledgeable and works hard to get to know what every client needs to be successful. His enthusiasm is infectious and his program prepares you for optimal performance both mentally and physically in the exercise room and in daily life. I can’t say enough about Coach Peter and all the coaches at Impact. I highly recommend Impact if you want to get healthy and strong and be rewarded with living your best life!

We started working with Peter about 2 months ago. Having worked with multiple coaches and trainers over the years, Peter is phenomenal. He is smart, funny, observant and above all one of the most dedicated people I’ve ever met.

I joined Impact nearly 6 months ago with zero experience in any formal fitness regimen. Peter assessed where I was, where I wanted to be, and helped me build the skillset I needed to see drastic improvement both quantitatively and qualitatively. This is the only gym I've ever been able to stick with long term. If you want to make a change in your life, go see Peter and the team.

Joining Impact Metrowest 5 years ago is one of the best decisions I've made for my long-term health and fitness. Peter and his staff are really top-notch coaches with a commitment to focusing on overall health and fitness. The small group training provides the perfect mix of a supportive, motivating community and individualized attention to address my specific goals. It can be hard to motivate to get to the gym at the end of a long day, but this team keeps me accountable for showing up - and at the end of the session I'm always glad that I did. Whether you are a fitness veteran or simply looking to get started with a healthy lifestyle, you'll realize tremendous benefits at Impact Metrowest.

I joined Peter and his team a few months ago. I'm so glad I did! If you're looking for accountability they definitely hold you to it! They keep you motivated an engaged. Tiff's classes are the best! Their program gives you individualized training in a group setting. If you have an injury, they give you a guidance on how to train appropriately without further injuring yourself. They also teach you how to prevent overtraining which is much easier to do than you would think! If your serious about getting healthy Impact is the place to join!

I am a fitness instructor myself, but was feeling like I needed a little something extra in my own fitness journey about 8 months ago. I found Impact through a google search and was intrigued by the small group personal training format and decided to give it a try. From the moment I first contacted the gym, Peter was incredibly attentive and made sure to understand my "why" so that he could best support me in my fitness journey. Classes are certainly difficult, but not so hard as to leave you feeling defeated which I appreciate. Peter & his team are willing to put as much effort and time into your journey as you are! I am now 20 weeks pregnant, and I couldn't be more grateful for Impact throughout this process. It has made me stronger and leaner (until I got pregnant) and now has left me feeling strong, capable and MOBILE over the last 20 weeks. I can't stop saying how great I've felt so far throughout this first half of my pregnancy and I attribute a good amount of that to the type of work we do at Impact. The modifications allow me to continue to get a great workout but take into account that changes my body is going through and I value how much Peter & his team are able to adjust the workouts to fit whatever you are dealing with in life. Can't wait to continue exercising through the next 20 weeks and then to build my strength back up post baby!

Coach Pete and his growing team of trainers and coaches are amazing! They are so focused on making sure we use the correct form and understand why that correct form is so important. They are so attentive to everyone even in a group setting and customize exercises to meet the needs of clients. Plus they make the hour-long training fun and engaging. Highly recommend Impact Metrowest!
