Zac is the best personal trainer I've worked with (and continue to work with)! Zac is an expert on the human body and takes the time to educate as well as train. Because of Zac, I have built not only strength, definition, and flexibility, but confidence in the gym and a keen understanding of what exercises to do to impact specific muscle groups. Zac is an incredible listener and keen observer, often anticipating my needs before I do. He will adjust our session plan on the fly depending on those needs, ensuring I do not injure myself while still getting a good workout. Finally, Zac is a calming presence breath of fresh air. I have a very demanding job and find I carry that tension around with me. An hour working out with Zac not only rejuvinates my body, but my soul. I feel refreshed and ready to enjoy life.

"I have been training with Marcelo for the last 18 months, and it has been a transformative experience physically & mentally. Marcelo takes the time to understand his clients and their needs genuinely connecting with them to provide a personalized training plan. His advice and instruction considers the entire person and not just the athlete, making for a very individualized experience. He is able to explain complex movements in simple ways that make it easier to understand how to engage my muscles in the most effective ways. I cannot recommend Marcelo enough regardless of fitness level or experience."

I have been working with Zac for 2.5 years and 1 year remotely. The entire time Zac has been incredibly kind, engaging, and hardworking. The workouts he writes are engaging and exciting and motivate me to get my workouts in. When working out in person, Zac is always professional and exciting to work with. He cares deeply for his clients and always has a warm and positive attitude. As someone who has off and on struggled with being motivated for the gym, working with Zac has been a game changer. Since working with Zac I have gained confidence in the gym, lost weight, gained muscle mass, and have stayed motivated to be in the gym at least 3 times a week for the last 2.5 years without miss a single week. Working with Zac has changed my life for the better and I could not recommend him more highly.

I started working with Marcelo about four years ago and have not regretted a minute of our sessions! I have never heard one word of criticism from him; he approaches training with a mixture of support, encouragement, and understanding. It's only in the past few years that I committed myself to paying more attention to my body, and Marcelo has designed a workout system that is tailored to my needs and abilities. Through a variety of stretching and strengthening exercises, I am able to follow through at home in between our sessions, and I have come to realize new confidence and a better self-image. Considering my age (I'm 81), this is becoming the best time of my life!

Zac is a great trainer and we highly recommend him! Over the last three years, Zac has helped us gain strength and improved our athletic endurance. He has also helped us feel more confident in the gym and taught us good technique, which is helpful when we train by ourselves. I love that Zac prepares for our workout prior to our session and always keep detailed notes about our progress. Zac is able to help us get results while being compassionate and kind. Thank you Zac for helping us feel more confident with our body!

I always thought I was someone who hated exercise, and I'd never felt in shape before. The trainers at Kinnect BodyLab have that mythical combination of pushing you without being harsh and pumping you up without being annoying. In a matter of months, I feel stronger than I've ever felt, and I'm addicted! I'll work with Kinnect as long as I'm able, and I'd recommend them to anyone and everyone.

Zac has completely changed my life. I went into my 30s completely clueless about fitness and nutrition, and with very low self-esteem. Right away, Zac made me feel so comfortable and seen. He is encouraging, patient, kind, and funny. He crafts workouts based on my needs, both long-term and short-term, and will continually check in to ensure goal alignment. I worked with Zac twice a week for two years. Before him, I was exercising maybe once a week, now I exercise almost every day. Fitness transformed from the most intimidating aspect of my life to the most rewarding. After training with Zac, I am fearless in the gym and look forward to moving my body every day. He's encouraged me on my journey in and out of the gym, giving me the tools to weave wellness into all aspects of my life. Working with Zac was the best gift I could give myself.

“Training with Marcelo has been quite an awesome journey! I have had a trainer for 3+ years before him, and I never really made substantial progress. After COVID hit, I started to build a home gym and train with Marcelo. The results have been spectacular. Marcelo mixes up weight exercise, strength training, and bodyweight exercises which makes working out really fun but also challenging.”

“I went to the gym on and off before the pandemic hit. Then the gyms closed and my body started falling apart. I started working with Zac after a friend recommended him. Not only did I get my body back without the gym, I FEEL hotter than ever! Zac has a way of understanding how I'm feeling physically and mentally and then addressing my body and psyche accordingly.”

I highly recommend Zac as a personal trainer. I’ve been working out for years on my own but decided to hire a trainer to get some new workout routines. Not only did I learn many new exercises, he also helped me to fix all of my bad habits as well as teach me how to better position my body to get the maximum benefit from each exercise. He listened very well to my workout goals and limitations (previous bicycle accident injury) and aligned my workouts accordingly. He’s very professional, personable, kind, punctual and fun to work out with. I always looked forward to my sessions with him! Again, I highly recommend Zac. Whether you’re new to working out, or if you just need a workout restart, you will benefit from his expertise.

“Mornings with Marcelo are the happiest time of my week! I’ve been training with Marcelo for more than three years now, and while I lost 30 pounds during our first year together, I’m even more proud of the newfound confidence and love for my body that I’ve gained. I’m stronger than I’ve ever been, and while I love how I look, I’m even happier with how I feel!”
