  • Amy Maschue


    Owner/Coach Amy Maschue in known for her motivation skills. “I want to know what motivates every athlete here so I can hit those triggers when they are in the gym,” she says. “I want to know what their favorite music is, what their favorite movements are, what they hate. Yes, it’s a bit extreme, but these things matter. They are the things that can make or break a workout, and they are important!”

    Before Opening Upper Limit, Amy worked as a personal trainer and group fitness instructor for more than 16 years. She was a national bodybuilding competitor for 7 years and holds the 2015 Arizona State Women’s Masters Division first place in Olympic Weightlifting.

  • Rebecca Nathan

    CFL-1 Trainer

    Coach Rebecca Nathan is an accomplished fitness enthusiast who brings her 13 year competitive soccer background to her coaching style. “My coaching style blends my passion for fitness with my eye for mentoring. I want to help my athletes reach their performance goal,” she says. “There is no greater satisfaction than being an accompaniment to your athlete’s success.”

    With 5 years as a CrossFitter and coach, she specializes in gymnastic movements. “I love helping aspiring athletes reach their first pull up, handstand push up, or double under repetition.” When asked how she got into CrossFit, she mentions a lifetime of fitness. With a family who worked in the fitness industry, from a young age, Rebecca was encouraged to pursue athletics. She found CrossFit by accident, however. “I was a “sweat junkie” always trying to push harder in the gym and challenge myself. I was dared to attend a soon-to-be known CrossFit class and fell in love.”

    “I want to help members reach their goals, while being able to smile and laugh along the way,” she says. “I truly believe fitness can revolutionize your life; when you find your niche, your potential is limitless.”

  • Tess LeBlanc


    I started CrossFit in February of 2016, have been consistently crossfitting the past two years.

    I don’t really have a speciality.. other than usually always smiling and trying to make people laugh

    I’m passionate about CrossFit. Through crossfit I have overcome so many challenges. Inside and outside of the box. I’m doing things now I never thought I’d be able to do! My coaches and friends I met through CrossFit helped to challenge me and push me, and from that I’ve grown a lot as a person and an athlete.

    I love watching people overcome their fears, or accomplish things they never thought they’d be able to do. It is so exciting to watch someone get their first pull up, or toes to bar, or PR on a lift they’ve been struggling with.

    I played basketball from second grade up until high school. In high school I didn’t play any sports.

    I have been doing CrossFit for 3 years, and like I mentioned earlier, my coaches and friends that I’ve met through crossfit have had such a positive impact on my life and have inspired me, that if i could inspire just one person, i would be super happy.

    I am super new to Arizona, but so far I am loving it!

  • Jezel Bow


    Coach Jezel Bow joins CrossFit Upper Limit’s training staff, bringing 10 years of CrossFit experience along with her. When we ask her how she came to be a CrossFit coach, she references a lifetime of athletics. “Fitness and health have always been an interest of mine,” she says. “I saw results with CrossFit and felt like helping others see results as well. I believe that it works. I wanted to encourage others in their fitness journeys.”

    Jezel knows that success means overcoming challenges, and she loves to encourage members to grow both inside, and outside of the gym. “I enjoy helping others reach their fitness goals, body goals, and seeing members accomplish goals outside of the gym because they felt inspired by a workout,” she says. “There’s something about suffering through a workout with people that helps to remind me how resilient we all are. We are all capable of much more than we think in all areas of life.”

    When Jezel isn’t at the gym, she can be found trying new recipes, or exploring the Arizona great outdoors with her husband and two daughters.
