Fitness & Weightloss Testimonials

“Thin is not necessarily well. I learned that the hard way. I have been obese and suffered from back pain for most of my life. After losing over 100 pounds, I realized that I had also lost a lot of muscle. I could no longer lift a 50 lb. bag of dog food and tired easily.  I ran the Boston Marathon in 2016 after spending thousands of dollars on physical therapy to get me to the finish line. I came to Peter to help me run faster. I got SO much more! Coach Peter and Duncan have worked to keep my body aligned and to stretch, strengthen and stabilize. I just feel stronger, my posture has improved and my lower back is almost 100% pain-free. You can’t put a price on that. I ran Boston again last year, slower and stronger than ever. Every day movements are easier and that is what is important. I would rather grow old and be able to lift that bag of dog food than to run faster in a marathon. I am eternally grateful for having Coach Peter and Coach Duncan in my life. The health benefits far outweigh the cost. I can’t put a price tag on living a pain-free life!”

“I have had so many compliments on my new figure I was almost overwhelmed with question. I cannot thank you enough for getting me back where I needed to be, no dizziness in the morning, no sore aching bones when I get out of bed and enough energy to go all day. Its like I have a whole new rested body actually a whole new me. I wish everyone could only realize ALL the benefits from taking less than an hour a day to get yourself feeling like you can take on the world.

I promise you I had over a dozen women at the party asking me what I was doing and where I was doing it! They have no idea the difference in your body from a workout at the gym compared to what you can achieve with IMPACT. Even my brother is absolutely amazed at my transition and energy in just 4 short weeks.”

“In the past 12 weeks I dropped the last 13 pounds and now weigh less than 120 pounds! I have lost another 11.5 inches and 6% body fat with a total weight loss of 44 pounds. IMPACT Rocks!

If I had to give any advice to anyone reading this, I would say, don’t take too much time to THINK about it, just do it. You will be glad you did. I recommend joining IMPACT with a friend. Not wanting to let them down is a huge motivator. As a 50+ busy mom, wife, entrepreneur and competitive horse woman, I can tell you that I can do it and you can too.”

“I really didn’t notice any one thing that was affecting my health, but I realized I was moving a little slower in my soccer games! My wife signed me up for IMPACT. I showed up the first morning not sure what to expect but my coach was great! I never get board and each workout dedicates time to the muscle groups that need the most improvement. By the end of month I was able to do triple the amount of push ups and feel fantastic in my clothes. I look forward to the camp not only for the health and fitness results, but also the camaraderie. And with 3 young boys, I intend to stay fit to be a great role model for them.”

“I have never stuck to an exercise program and now I look forward to IMPACT. Every workout is different, productive and the hour goes by so fast. Our coach keeps us accountable so even on days that I would prefer to sleep in I know she is looking out for me to arrive. Within a short amount of time IMPACT gave me the stamina to keep up with the younger and quicker players on my soccer team. I could swiftly running across the field and felt so proud that my exercise had paid off. Because of boot camp I was able to play more competitively.”

“I have been athletic all my life but have never felt this strong. I have been training with Peter for 3 1/2 years. I am 43 with a set of two year old twins. I trained throughout the pregnancy and was back in 0-2 clothes in six months. More importantly my performance and endurance in all the sports I enjoy have never been stronger. That’s important to me because I want to surf and ski with my twins when they are teens. 3 hours a week with Peter has made my body feel the strongest I can ever remember.”

Michelle Blackwell

“I have been working with Peter McMahon since 2008. I continue to get stronger and leaner. After a year I had increased my weights to a point that I assumed that I could not improve further. However, more than 2 years working out three times a week for less than 55 minutes I continue to get stronger. I recommend this program for any inPidual who wants to get in shape and stay there.”

John Curren

“For twenty years, I have been one of Long Beach’s top triathletes. At the age of 48, I was starting to see a decline in my performance against my competitors. Luckily, I was introduced to Peter McMahon and his weightlifting regimen. By incorporating Peter’s program into my training schedule, I had my best year of racing in a long time. I felt stronger, recovered faster and only had to devote 90 minutes a week to weightlifting. It is like discovering the fountain of youth. It really does work.”

Deborah Causwell

Long Beach Triathlete

“I have had shoulder impingement problems since college, and little by little I was forced to abandon bench presses and overhead presses from my workouts because of intense pain. I felt I was wasting my time and money just working on the smaller muscles. But then I was introduced to Peter’s periodized workouts using the Functional Movement Screen. Muscles no longer were pinched between bones, and I was working to exhaustion on each set, not working until the pain was unbearable. And who wouldn’t like working out only 180 minutes top each week. Sure, I still dread going to the gym, but now it’s only three times a week and not five times. And I never grow tired of receiving compliments. So, if you see me, say something nice.”

Bob Cloutier

“After years of running, walking, biking and swimming, I felt I had reached my maximum level of fitness. After speaking with Peter McMahon 2 and 1/2 years ago, I decided to try his method of training. I have seen my strength and endurance improve dramatically with only two hours a week of training. I recommend StoneCore Fitness for anyone who wants to improve their overall fitness and health.”

Lisa Coleman

“I have quit every health club I have ever joined. I have stuck with this for three years now. I am in the best shape of my life even after having twins.”

Kyle Mercier

“I have been a client of Peter McMahon for about three years. He is a terrific instructor—attentive to inPidual needs, smart, and funny. He makes the workout a blast. I credit Peters instruction in weightlifting with my recovery from serious, debilitating back trouble. I am now stronger, more flexible, more mobile, and more active than I was BEFORE my disc problems. I have no more trouble with my back, thanks to the workout, and my energy and enthusiasm for life have increased tremendously. I work out with Peter about three times per week for 30 minutes a session, and I continue to increase my strength and improve my health. This has been a God-send.”

Rachel Kelly, Ph.D.

“I have worked out my whole life. When I started training with Peter a few years ago, I already had a high level of fitness. I have worked with trainers for years but I have never been consistently challenged with my workouts like I am with Impact Long Beach. I am 46 years old and am in better shape now than I was 20 years ago, thanks to Peter.”
