making a positive impact

Getting in shape is empowering! And while there might be a sore muscle or two along the way, it can be a really enjoyable journey that anyone can achieve, regardless of her/his starting point. A lot of exercise programs are intimidating, making them inaccessible to beginners. Humanus Fitness instead focuses on connecting people to attainable fitness goals that will ultimately improve health. Finding the fun side of fitness and adapting training programs to a clients' needs, pace, and desires is what Humanus Fitness is truly about.

My focus is on tailoring a fitness program to a client's goals and needs, while teaching the fundamentals of fitness, demonstrating proper technique, and keeping the workouts exciting.

I have been working with Francis while I recover from knee surgery and he is fantastic! I have a yoga mat and a few dumbbells, but he provides the rest of the equipment. We do the workouts in my small basement, but space is never an issue. I get a full body workout that is gentle on my knee, but leaves the rest of me feeling just sore enough I know I’m building strength. I especially love seeing the definition in my abs and arms. 

I highly recommend Humanus Fitness.
