Ian is very skilled trainer who really helped me to work through my lower back pain. He's encouraging and very knowledgable. He helped to make the gym a less intimidating place for me, and I built up confidence to strength train without injuring myself. I can't recommend working with Ian enough!
This is Susan Garsoe writing under Tim's Google post. I started working with Ian four months after my total knee replacement. I had already had one knee replaced, one hip replacement, and a shoulder reconstruction. (I also have to have the other hip replaced.) I dragged into the training center feeling stressed about my recovery and my general well-being. Ian made me well. I got stronger, had better energy, and the stress went away. He knows so much, and has a great ability to figure out when something doesn't work just right, and makes a subtle change that works. Ian gave me a really good set of home exercises that will keep me strong. The studio is wonderful: full of light, good music, and a great view of the mountains. And of course, Ian. I am 75 years old with osteoarthritis, and I am full of optimism. Thank you Ian. I will recommend you to anyone, for anything.
I worked with 3 trainers over several years prior to coming to Momentum--all were good, but Ian Merrin is in a league of his own. He has a remarkable depth of knowledge regarding anatomy and the mechanics of motion. He is excellent diagnostically when presented with specific symptoms, and he designs workouts tailored to restore function. He demonstrates exercises clearly and watches closely, always making subtle corrections to form. He is unfailingly prepared for each session, with a routine planned ahead of time. However, he is flexible in his approach, and adapts the day's plan if there are any new concerns. Personally, Ian is a pleasure; he is a really fine individual--direct, engaging, warm, humorous and always present.
Ian has been instrumental in getting me back to feeling strong and healthy but more importantly allowing me to do the things I love. I’ve been working with Ian for a year now after dealing with knee pain for a year and a half. My physical therapist had recommended Ian as the next step to helping me navigate my knee issues to allow me to run, hike, etc. Ian’s training is highly personalized and ever evolving. Every work out is highly tailored to my specific issues and needs. He is very aware of what my goals are and constantly adjusts to help me get back to being active. He seeks out ways to work around any issues that arise and constantly challenges me. Every work out I leave feeling stronger but never pushed to an unsafe limit. Ian has a vast knowledge base that extends well beyond simple strength training. His work outs are created to help you function the best you can in daily life and whatever activities you are involved in. His attitude is always positive and upbeat. Even when I come in exhausted from work Ian gets me motivated to work hard. I highly recommend Ian if you are looking for a highly knowledgeable , personable, and committed trainer.
I've been working with Ian, the owner and main trainer at Momentum, for 6 months now, and plan to continue. I find him to be an incredibly knowledgeable, personable, competent, and motivating person. A top sports physical therapist in the area recommended him to me, saying that Ian himself knows more about movement than most physical therapists. After working with him, I can't disagree. Ian is good at imparting his very detailed understanding to me. More importantly, he's helped me make significant progress on my fitness goals and successfully rehab some minor but functionally complex chronic injuries that I've dealt with for years prior. Ian has his own gym with all the necessary equipment for private training sessions -- especially nice during a pandemic. I would recommend him to anyone looking for personal training.
