Our Story
​
Hi! I'm Heather McCallum! LIke so many of us, I have had my own challenging relationship with fitness and my body. I went from being an unathletic adolescent who despised running and had tons of anxiety around organized fitness to becoming an exercise addicted, marathon runner who has qualified for the Boston Marathon multiple times! For me, running was where I found my strength and capabilities and it transformed both my physical and mental health. Running led me to discover the benefits of strength training and other modalities. I ran and lifted weights through both of my pregnancies and saw what a difference it made to my body and overall wellbeing. But the thing about becoming a mom is you suddenly have far less time on your hands! I needed to find a way to support my body as efficiently as possible. I needed a workout that was challenging, targeted every muscle group, got my heart rate up like running while making every minute count! I discovered Hot HIIT and it was the answer to everything I was looking for: the full body burn of high intensity interval training combined with the efficiency of heated exercise and that endorphin high! And I’m so excited to share this method with you! With nearly a decade of experience coaching fitness at Equinox, being a founding member of Stride Fitness, and working as a personal trainer, I've witnessed the transformative power of fitness firsthand. It not only enhances physical capabilities, but also empowers individuals to live life to the fullest! This inspired to open a studio where everyone feels welcome and uncovers new aspects of themselves. At Coming in Hot!, come as you are, discover your strength, sweat out your stresses, and leave as the best version of yourself, both inside and out!
