Amy Fielding - Personal Trainer

Amy Fielding

Amy, a former dance instructor, came to FA Boxing to train for her first sanctioned boxing match. She was immediately hooked by boxing, and the fun and supportive FA community. “It is a place where everyone knows your name, will push you to work your hardest, and will make you laugh.”

Her training philosophy is “Change is uncomfortable. Let’s get comfortable being uncomfortable…and let’s make it fun!”. She has discovered the joy and rejuvenation of trying new things, and she loves to share that with her clients.

As a Mom of four who has transformed her body through boxing, she particularly loves to work with Moms, pushing them to create a body even more fit than pre-baby!

Besides boxing, Amy’s other fitness passion is obstacle course racing. She currently leads our FA obstacle course teams, as well as teaches boxing and conditioning.

She has worked as volunteer in her hometown of Millis, and as a part-time assistant providing support to small local businesses.
