Mariah LeonardMariah Leonard

I’m an undergraduate student studying Kinesiology with an emphasis in fitness. I’ve always enjoyed being active; when I was younger, I was that kid whose feet were black from running around without shoes ‘til the street lights came on, but didn’t realize how much I loved being active until high school. Around that time I was very depressed, what kept me going were my trips to the gym, hikes, runs around the park, or roller derby practices. I used exercise to heal myself. Because of fitness I was able to turn my life around.

I’ve always thought about becoming a fitness instructor, I figured if exercise could save me, maybe I could use it to save someone else. When I heard about the group fitness training at the ARC I had to jump on it! GFIT solidified my passion for instructing and I also gained a newfound respect for the instructors and all the classes.

Sara McDonaldSara McDonald

I began teaching Group Fitness in 1995. Back then, I was working on my Master's degree and found that I was in the gym all the time - why not get paid? I love TAKING group fitness classes and wanted to give back by hopefully making exercise an enjoyable and challenging experience for my students. I get such an endorphin rush from both taking and teaching classes and I hope the students come away with the same endorphin rush. I definitely feed off the energy of the students, and hope I reflect back that energy for the students. Wherever I move, the gym is always the first place where I feel most at home. It's a place not only to deal with stress, anxiety, and even the isolation of being in a new place, but also a great way to meet people and create a community for yourself. I’m very excited to again be teaching on a college campus! Just prior to moving to CA, I taught for the Duke Group Fitness program while working on my PhD. I like the idea that I'm helping students build the healthy habit of a lifetime of fitness and that over the years to come, they benefit as much as I have from being a devotee of group fitness.

What I teach: I specialize in cardio kickboxing, High Intensity Interval Training (HIIT), boot camp, body weight and strength training, and circuit training. All of my classes use original choreography. I appreciate the wide variety of classes offered at the ARC.

My interests and hobbies: As a marine biologist, of course I love the beach, the sun, salt air, and sand between my toes, and being on the water in a boat. My husband and I have renovated two historic homes. Despite the hard work and many challenges, it's very rewarding when you finally achieve the finished product. The older I get, the more I enjoy hanging out with friends at someone's house for game night or watching some good shows - probably sounds boring to most people, but I really enjoy it!
