Cody Erwin is a strength and powerlifting enthusiast who applies biomechanics and movement science to help athletes train more effectively, move efficiently, and build sustainable strength while preventing injury. As a co-owner of The Body Shop, Cody brings a fresh perspective and a deep love for strength work. He’s passionate about creating an environment where people of all levels can explore their potential, learn proper movement mechanics, and develop confidence through consistent, intelligent training.

Tara Callaghan brings over a decade of expertise in the fitness industry to The Body Shop. She co-owned and operated Copper City Strength and Conditioning, Butte’s first functional fitness facility, alongside her husband, Anthony from 2012 to 2025. Tara holds certifications as a USA Powerlifting (USAPL) Club Coach, USA Weightlifting (USAW) Level 1 Coach, and has been certified as a CrossFit Level 2 Trainer and CrossFit Kids Trainer. 

In addition to her work in the fitness space, Tara works full-time in public and community health and holds both a Nursing and a Master of Public Health degree. She is also actively involved in several community boards and volunteers for various local events throughout the year. Outside of her professional roles, Tara is a proud mother of two—Spencer and Stella—and enjoys hiking Butte’s beautiful trails with her dogs.

Since 2014, Krissy has coached athletes in both CrossFit and powerlifting, launching the powerlifting program at the former Copper City Strength & Conditioning, and helping countless members improve their squat, bench, and deadlift. She is a CrossFit Level 1 Trainer, a USA Powerlifting Club Coach, and holds CrossFit Gymnastics and CrossFit Kids Certifications. A “semi-retired” competitive powerlifter, she’s held Montana state records in USAPL and brings that same competitive drive and technical expertise to The Body Shop.

But more than numbers on the bar, Krissy is passionate about training people for life…whether that means picking up grandkids with ease, being fit enough for a once-in-a-lifetime hunting trip, having the strength to carry a loved one out of a burning building, or simply building muscle and confidence on their own terms. Currently pursuing certification in training pre- and post-menopausal women, she’s deeply committed to helping athletes of all ages and backgrounds build strength that lasts.

Outside the gym, Krissy runs a nonprofit consulting business and stays busy adventuring with her three dogs and husband, Nate, or volunteering for a community project. She loves local food, hiking, skiing, riding, tackling home projects, sipping a Headframe cocktail, and the occasional true crime podcast binge.

Anthony has been involved in functional fitness for over 10 years now. After years of on-and-off training that didn’t seem to get results and didn’t keep his interest, Anthony stumbled upon functional training. He instantly loved this style of exercise, largely due to a plethora of movement disciplines combined with the fact that he could get a great workout in an hour or less! The large number of movements kept exercise novel and fun. The intensity kept workouts short, allowing this young father to guard time for himself and still have enough time left over to devote to work, recreation, and family. Anthony decided in early 2012 to bring the joys and challenges of this exciting training methodology to Butte, America, by opening Copper City Strength & Conditioning with his wife, Tara. After 13 years, and recognizing the demand for fitness flexibility, Copper City’s group model evolved into a 24/7 open gym (and later rebranded as The Body Shop).
