Housed in a warehouse in South Boston, Peter Welch’s Gym has earned a reputation of being hands-on, no-nonsense, old school, a community center where world class fighters train alongside college students, moms, dads, and kids – all achieving extreme improvements in strength, speed, stamina, balance, agility, and (for many) weight loss.
Peter Welch’s Gym originally started out as a place for boxers to train. Over time, fitness enthusiasts became interested in our fighter training as a means to enhance their athletic endeavors and blue collar individuals saw the potential that this type of functional training brought to improving their job performance. With a strong word of mouth, the gym begin to attract people of all ages and skill levels who were seeking a challenging, spirited and varied workout that got amazing results!

Peter Welch’s Gym prides itself on being a neighborhood boxing facility that provides everyone a knockout workout.
