I’m a busy blue collar guy. My work schedule is completely erratic, and I also have a wife and 3 children with very busy schedules. Mark was able to fit a workout and meal plan perfectly to my needs. He’s everything I could ask for in a coach. We hit the ground running a month ago and my results speak for themselves. 10/10 highly recommend. More...

Mark is super accessible. He answers every question I have and I have never had such great results in such a short amount of time.

I could not recommend Mark more! I’ve seen changes in my body I never dreamed possible. I feel healthier too. On top of that, he’s a great person, life coach, and cheerleader. If you give it a try you won’t regret it! More...

I’ve been working with Mark for 2 months. The physical changes in this period of time is remarkable. Mark answers every question and encourages along the way to my goals. HUGE shout out to Mark.
Erik
Mark has been amazing since I have signed up with him. He is very real and doesn't try to shovel some fad diet or workout routine on you promising to get results in a ridiculous period of time. He takes the time to explain the journey and how the results you will get will be sustainable and long lasting. I am really grateful to work with someone of his integrity, commitment, and honesty. I have achieved the best results in my life. More...

Mark is absolutely excellent to work with. In 6 months, he got me down 40 pounds and helped me build the lean muscle I’d tried so hard to build on my own. I truly would not have been able to do this without him. Can’t recommend him enough! More...

Mark rocks ! He gave me the direction and support to transform a 53 year old dad bod into the “ hot guy “ at the pool. Amazing meal plans, I actually look forward to the workouts he creates ! Mark will hold you accountable, he knows when to add the appropriate amount of humor to make it all work. I hope others are able to have a positive experience as I did. More...

Mark is an amazing coach - so patient, knowledgeable and kind! I worked with him while training for my first marathon, so fueling properly and getting proper strength training while staying injury-free were obviously very important to me. I was able to exceed my goals and he was always willing to offer advice and adjust to my needs. He provided me with a very thorough and easy plan to follow with some really amazing recipes (that I still use today)! Thank you again, Mark!! More...

I worked with Mark Rosenberg over several months and I went from 220 to 188, and it wasn’t just about the weight — I gained muscle, energy, and stamina, which is no small thing in your 50s.
Mark made a meal plan that actually worked for me — it was tailored to my muscle and weight goals, and the food options were surprisingly good (I was worried I’d be miserable, but it wasn’t like that at all - meal prep was easy/fast). Funny how food becomes a secondary thought when you see your body progressing - haha.
His weekly training plans were varied and sustainable without burning me out. We also met once a week to train together, and that work out always felt like I went further than my last working out. I was surprised at my own strength and growth often. While helping you through your work out he's also an easy going guy in the gym - We laughed a lot.
Highly recommend working with him. I’m planning to start back up with him again soon.

Mark is an excellent coach and guide through the diet/fitness journey. When I first started with Mark, I was self conscious and didn't even feel comfortable stepping into a gym. After seeing some results (quickly, I might add), I felt not only confident, but eager to go to the gym and work out. His diet plans are thoughtful, and require minimal meal prep. Even though it was only 3 months, Mark taught me the tools to continue this journey for a lifetime. More...

Mark is not only an incredible coach. He is an amazing human. After my divorce I was depressed with a dad bod. He has not only completely changed my physique but helped me when I was feeling dark and wanted to give up. He not only changed my body. But my mind. I have told him this many times, but I feel I owe him a debt I can never fully repay. I am beyond grateful. You will be too. (No I wasn’t paid for this. lol) More...
Ryan Chrisenberry
Marc is an absolute professional! He was patient with me during the times that I would start to get discouraged and he would motivate me to continue to keep pushing forward and I am so glad he did. He is thorough and willing to answer any questions you have about any of the protocol. I was only with him for a short three months, but I am looking the best I have in my entire life.I cannot recommend him enough! More...

Working with Coach Mark has been a truly transformative experience. From day one, he made my fitness goals feel realistic and attainable.
His workouts are challenging but always manageable, and he tailored them to fit my lifestyle and experience level. Thanks to his consistent check-ins and encouragement, I’ve stayed motivated even during tough weeks.
I’ve not only lost weight and gained muscle, but I’ve also learned how to confidently navigate the gym—something that used to intimidate me. Mark’s approach is supportive, practical, and incredibly effective. I’m stronger, leaner, and more energized than I’ve felt in years. If you’re looking for a coach who truly cares and gets results, I can’t recommend Mark highly enough!

Working with Mark Rosenberg has been a complete game-changer. As both a trainer and nutritionist, Mark brings knowledge, professionalism, and genuine passion for helping his clients reach their goals. He is thoughtful, challenging, and tailored exactly to what I need. His nutrition guidance is personalized and sustainable, and I’ve felt stronger, healthier, and more confident than ever since we started working together. If you’re serious about investing in your health and want someone truly exceptional in your corner, I can’t recommend Mark highly enough. More...

I had been training for a year and just wasn’t progressing the way I wanted to. I found Mark online and he has changed my perspective, educated me, and helped me achieve so many goals I didn’t think were achievable.
As of this review, I’m about 120 days into my work with Mark, down nearly 30 pounds and showing cut muscle in places that I never knew I could.
Mark has been the accountability - but also the education - I needed to take my fitness accomplishments to the next level.
10/10 - will ALWAYS RECOMMEND Mark!

Pete
Mark is a master at his craft. I’m on my third training cycle with him and couldn’t recommend a more knowledgeable and accessible Coach. Responds within minutes and is a constant source of motivation in helping me reach my strength and conditioning goals. It’s not always easy finding a strength coach with a massive nutritional knowledge base that will custom tailor a plan for maximum results. Mark is that guy no question! More...

Mark got me on the right track for success and something I can easily stick to. In 3 months I lost weight kept it off and started seeing muscle where fat used to be.
Justin Palmer

Mark is a wonderful trainer. I have been working with him for months, and his custom approach, constant evaluation, and adjustment are what my body needs to get where it goes. In addition, he practices what he preaches, and it is easy to stay motivated when you see where he actually began.... It is inspiring More...

Mark Collins
Nutritionists & Dietitians
Mark was very eager to help me become healthier by changing what I should be doing in n terms of both food and exercise
How important is a healthy diet to someone’s health and wellbeing?
Super important. Getting in the groove of eating well and taking care of ourselves helps offset health risks that may occur later in life such as diabetes, heart disease, high cholesterol, etc. Eating well and exercising regularly makes you feel good and everyone wants to feel good.
What do you love most about your job?
I love watching people succeed in their goals. Nothing makes me happier when than when a client reaches a milestone they've been striving for. It's the best part of this job.
What inspired you to start your own business?
My mother was ill about a year ago and it was due to her food intake. I helped her fully recover and being able to do that and watch her progress was such a pleasure to do for a son to a mother. It made me realize just how important our diet is to our health and I wanted to help others.
Why should our clients choose you?
All of my clients have had success in their goals. I bend over backwards to ensure the success of my clients and grant all of them 24/7 access to me--something most nutritionists and coaches do not do.
