Eric Siegel


I found CrossFit after playing NCAA Division III soccer and dabbling in recreational running while working a desk job. CrossFit has allowed me to pursue my passion for fitness on a daily basis and has helped me to reach some life long goals, such as running marathons, as well as other achievements I couldn't have dreamed of, like competing in the CrossFit Games, as well as national and international weightlifting meets.

It is my pleasure to share my love for training, and learn from individuals of all ages and ability levels. I look forward to the opportunity to work with you!

I started CrossFit back in 2015 at a time when I was the most out of shape that I had ever been. I grew up playing sports throughout high school, but once I hit college, I realized that I had no idea how to stay active and healthy on my own. The freshman 15 quickly turned into a freshman 25 plus. Like most people, I thought that spending mindless hours on the treadmill mixed in with a few crunches was the way to go. That worked for a while, but I never, never, looked forward to going to the gym.

I’m not going to lie, I was intimated by CrossFit at first. However, I was quickly surprised by how welcoming the community was. Some of my best friends to this day are people who I’ve met through CrossFit.

This was also the first time in my life that I found things I genuinely loved doing at the gym. Lifting heavy weights felt empowering – and honestly, just straight-up fun. I was able to channel my competitive energy into a productive outlet. I still continue to find myself learning something legitimately every single day. Plus, hey, when you are able to attack workouts that feel impossible, that mentality carries over into every other area of your life.

CrossFit 781 has been my second home for about 4 years now. I can truly say that sharing fitness with others is my life’s passion and the reason I wake up excited every morning.

I joined CrossFit 781 back in November 2012 and from day 1 my passion for it has only gotten bigger every single year. I only wish that I had discovered CrossFit sooner. Before CrossFit I would mainly stick to the elliptical, an occasional Bootcamp and Zumba…. Yes, Zumba ? I received my Bachelor's in HR from Bridgewater State University and Masters in Business Management from Eastern Nazarene College and have worked mostly in Financial Services jobs; but my interest in Health and Fitness has kept growing.

My passion (or obsession?) for CrossFit is matched only by my passion for animals, tattoos and country music, and I will travel for any great concert.

Growing up in Weymouth, I was a 3-sport athlete in high school and played hockey for Stonehill College. Some lingering sports-related injuries led me to focus on long distance running for several years, post college. That put added strain on my body and convinced me a change of exercise programming was needed. I found CrossFit in July of 2013, after hearing great things about CrossFit 781 through some friends. Despite my first workout of burpees and prowler pushes nearly making me sick and questioning my choice, I was hooked.

There was something about witnessing people around you pushing to their limits, working so hard, and trying to get better – it was so motivating.

I spent several years competing and pushing to the absolute max, day in and day out. While my competition days are over, and PRs may be fewer and farther between nowadays, the feeling of working so hard that you are forced to writhe around on the floor after a workout is a something that will never get old.

Coaching and fitness offer a nice balance to my day to day marketing career in the telecommunications industry.

I grew up in Braintree, MA where I attended and played basketball, field hockey, and lacrosse for Braintree High School. Following high school, I went on to play lacrosse at the collegiate level and later began coaching the sports I grew up loving. From varsity women's lacrosse, to youth basketball, coaching became a passion of mine. The skills and tools I have acquired over my athletic and coaching career have made for a smooth transition into doing and teaching CrossFit.

I discovered CrossFit after a friend had asked me to try out a class at CrossFit 781. I was instantly hooked. The intensity, and the competitiveness of the sport was alluring, and I wanted in. Over my CrossFit career I have not only lost weight and improved my level of fitness, but I have gained self-confidence I never knew I had.

The knowledge I’ve obtained in regards to functional fitness and nutrition is something that I am very excited and passionate about sharing. I look forward to helping others reach their fitness goals, and to continue to becoming more educated on the different areas of CrossFit.
