Kristyn crouches on the floor to pet her dog, Burton, while they both look at the camera. Kristyn is smiling and Burton has his head cocked to the side. The Shred Strong logo is painted on a wall behind them.

What’s Up, I’m Kristyn Mastroianni.

I’m a 23-season snowboarder, Strength Coach, and Orthopedic Massage Therapist. I help snowboarders level up their riding and shred for life through manual therapy, strength training, rehabilitation, and sports nutrition.

Through Shred Strong, I offer more than just training. As a snowboarder and Licensed Massage Therapist, I’ve been able to combine my passions to help you not only shred through your pain, but to heal from it, move better, and get stronger – mentally and physically.

I believe in my clients, often in ways they don’t believe in themselves. I’m real. Who I am outside of the gym is who I am in the gym.

I’m not a bubbly cheerleader, but I also don’t push people past their capacity. I will never give someone something they can’t do – even if they think they can’t at first. Sometimes believing in your own strength is the hardest part, and I understand that.

I’m an advocate for the importance of recovery, and I’m passionate about teaching people that strength training is so much more than just going into the gym and beating the shit out of yourself.

IN-PERSON TRAINING

A client holds a side plank with her legs resting on a bench and one arm extended in the air. Kristyn holds the outstretched arm, checking her client's form.

ONLINE TRAINING

REHAB

A client lies on a wooden bench, arms crossed over his chest, one of them in a sling. Kristyn kneels at his head, placing her hands on his forehead, doing gentle massage.
Kristyn's daughter slides down a snowy bench, wearing full snowboarding gear and helmet, smiling happily. Kristyn spots her with arms outstretched, also smiling.

Beyond my expertise in strength training, mobility, and rehabilitation, I started Shred Strong because I love snowboarding, and I want to do it for the rest of my life.

My path here started when I failed out of college in Vermont for snowboarding all the time and skipping class. And I don’t regret it for a second.

Immersing myself into that mountain life taught me more about who I am – and who I want to be – than school ever could. I struggled to learn in conventional ways, so I found an outside-of-the box way to create a future for myself. My goal when I left Vermont was either to move back or create a life where I could ride mid-week.

It took about a decade of growing my biz, but here I am!

If you love snowboarding - or want to love it - you’re in the right place.

Snowboarding is something I do with my family, too.

I put my daughter on a snowboard at 10 months. She giggled and loved it from day one. She is now 3 years old in her third season, and she absolutely loves snowboarding!

And whether we work together virtually or at my Manchester, Connecticut location, you can also expect to meet Burton the Dog - the official Shred Strong mascot.
