Marvin Ambrosius

Founder/Fitness Trainer

I am a certified instructor and I have created my own short but intense fitness routines that even professional athletes can get something out of. I had an idea for a fitness app that would help people at all levels of fitness and mentioned it to one of my colleagues who had been attending my classes for the past year. They offered to partner up and develop the idea to build the fitness app. Shortly, after that conversation, a meeting was scheduled and in that meeting, Fit-in-5 was born.

I run my own clinic in London seeing clients both online and in person, my goal is to help my clients achieve optimal health with a focus on gut health, as I believe this is often the root cause of most illness.

Fit Freaks Review

Marvin is a fantastic trainer – he knows how to tailor our sessions to my fitness goals, but also keeps them varied so that I’m learning new drills and exercises all the time, and then I can use them in between sessions. He always helps me work to the maximum and does it with a smile on his face​.

I am loving the Fit In 5 workouts. It’s really inspiring to be able to condense workouts of five minutes to really target the areas you want to. And to be able do this at home absolutely brilliant. You don’t have to pay money for a gym membership.

Fit Freaks and their workout sessions are ideal for those who lack time to ‘fit in’ any exercise due to a busy lifestyle. The great thing about Marvin’s Fit In 5 high intensity workouts is they raise your Excess Post-exercise Oxygen Consumption (EPOC) level after you’ve completed them.
