"Iron Gym changed my life. I came in 40 lbs overweight and barely able to run a mile. After 6 months of personal training with Mike, I've lost 38 lbs and completed my first 5K. The trainers genuinely care about you."

"As an independent personal trainer, renting gym space here was the best business decision I made. Professional environment, great equipment, and the staff are incredibly welcoming to outside trainers and their clients."

"Ava's small group classes are INSANE. I've tried every gym in Boston and nothing compares to the energy here. The class sizes are small enough that you actually get attention and corrections — not just shouted at."

"Been a member at Iron Gym for 3 years and the open gym is everything. Great hours, never overly crowded, and the equipment is always in perfect shape. Worth every penny of the membership."
