Quick details: COVID lockdown plus work from home = gained a lot of weight with non-existent exercise and eating very poorly. After 6 months training with Rob(and in conjunction with my PCP), no more blood pressure or cholesterol pills. It has been work in both the gym and in my habits at home regarding cardio and diet. Rob is there to support both. I'm not completely there yet, but it's not the end result, it's the day to day grind. Rob has been there every step of the way and took this desk jockey who never played sports that went to a Planet Fitness for MAYBE 3 months, to crushing personal

I began working with Rob in the fall of 2020 as an online client and have made a significant amount of progress working with him. He has taught me a lot about various training techniques that maximize muscle breakdown inside the gym. Not only is he very knowledgeable about training, but he also reminds you that food is the number 1 anabolic. Before working with him I was overtraining and overthinking the nutrition aspect. Rob formulated a scheme for me to follow that enabled my body to have an ample amount of rest and recuperation to maximize muscle hypertrophy. I weighed approximately 170lbs when

My husband and and I have been an online client of Robs for nearly the last year. Rob is by far the best trainer out there! He is motivational, tough (in a good way!), friendly, and truly knows how to burn fat and build muscle. His workout and nutritional plan has helped me completely transform my body. When I requested to work on specific body parts he put together workouts that lifted, firmed and toned those areas. I highly recommend Rob if you are looking for a lifestyle change.

Rob is the man!! My wife and I were online clients but we felt like we were in the gym with Rob for nearly a year!! He help us totally change our lifestyle and out look on all levels. He was a one of the catalyst to help us gain confidence in our bodies and mind.

Rob really puts in his heart and soul as a trainer and he does not just prescribe a nutrition and training program and leave you to follow it without guidance. He tracks his clients' progress regularly, and offers good support in a holistic way including lifestyle changes. I have been working with Rob in my off-season prep and precontest prep alike over the years, and have only good things to say about the passion, dedication, and knowledge he injects into his work. Even as a competitive athlete myself, I can see it. (As a note, I am based in Singapore currently, and have worked with Rob online

I would recommend Rob to anyone looking to learn and gain muscle. Rob is by far the best trainer I have had and is a great guy as well. Over the past few months, I have made huge improvements in form, conditioning, diet, and muscle mass. I am extremely satisfied and will be continuing to work with Rob online while I am at school.

I have been training off and on for 7 years and for the first time I feel like I am investing where it counts. Rob is an amazing motivator and trainer , I came in with a few medical conditions but he has not allowed me to use it as a crutch ! Rather he works around my health and has made me understand that I am still in control no matter what I have going on. I came in with concerns on my image and while results have been amazing he has also helped me shape and mold my mind. Rob you should be cloned ! Thank you for all that you do !
