Can't say enough great things about Justin and the results are wonderful! I've been very active my whole life but have never used a trainer before. He helped me work through multiple injuries and correct years of improper technique. He listened attentively to where I wanted to improve, conducted a thorough analysis, created a custom plan, and worked with me in person to ensure I was getting the most out of every movement. Thanks Justin!

I went to see Justin to get more gains on my strength training. What he discovered was a large imbalance in my use of muscles. He developed a thorough plan to get all my muscles firing and in the process significantly increased my range of motion which had been limited due to a connective tissue issue and improper training. I am now effectively using form to engage and grow the muscles properly. His professional knowledge is top notch. He's not just any trainer. I can't recommend Justin enough.

Justin is an incredible trainer. He is patient, knowledgeable, professional, and kind.
I started training with him after months of not seeing results at the gym. Within the first month I began to feel AND see results. His extensive knowledge of fitness, nutrition and recovery has made all the difference. I’m confident he can help you reach your goals no matter where you are in your fitness journey.

Justin is truly one of the best coaches I have ever met. He cares so much about his clients and has all the knowledge to get the results you want. I cannot tell you how much I enjoyed workouts with him knowing that I was getting better and stronger with each one. He is incredibly knowledgeable and can support your fitness journey in a wholistic way that not many others can.

Justin is one of the most passionate and knowledgeable personal trainers I have ever worked with. He provides a very detailed and individualized approach to work toward your specific goals. Don’t hesitate, reach out now! You won’t regret it!

Wish would have found Coach Justin sooner. My son has made great improvements since starting with Grit 2 Greatness. Coach takes a personal interest and is open to specific goals my son is wanting to achieve. Definitely not the cookie cutter approach.

In a short amount of time the improvements he has gained has been noticed by his school coaches.

Absolutely recommend. You will not be disappointed.

My experience at JCollen-Training has been exceptional! Justin has a vast knowledge in nutrition, weight lifting, and teaching proper form & engagement. After trying many different workouts, I’ve found that my one on one sessions with Justin is where I need to be. In just a few sessions Justin has taught me correct form and how to get my entire body engaged when lifting weights. I no longer leave a workout sore from bad posture and doing the workouts wrong, but leave them feeling great and stronger. Justin has made mid-workout adjustments after seeing my body shutdown that helped me still finish my workout without lowering the weights or reps. I couldn’t be happier with my experience @ Jcollen-training!

Last but definitely not least, Justin has shared his knowledge with me about nutrition and living a healthy lifestyle. He assisted me in making small adjustments that produced big changes in my energy levels and overall weight & muscle growth.

Justin Collen is a true professional. Justin not only has the formal education but practical experience as a coach and athlete. My experience thus far has been top notch and I haven’t left a session without learning something about myself. If you want real solutions then go to JCollen strength and Conditioning. As a former college athlete and former professional fighter and a firefighter, I can say with confidence that it’ll be the best choice that you’ll make for your physical performance.
