TRX Founder Welcomes All to Stay 'Mission Fit' at TRX Training Center

By Kelly Church

When former Navy SEAL Randy Hetrick fashioned together the first TRX strap to stay "mission fit" during his time in the military, he had no idea the lightweight contraption made of an old jiu-jitsu belt and parachute webbing would become his next career and a fitness revolution. Hetrick, now the owner of San Francisco, CA's TRX Training Center, used his handmade bodyweight device as a mobile gym.

TRX is a form of suspension training; straps with handles are hung from the ceiling and bodyweight exercises are performed. Everything from upper body and abs to lower body, and even cardio, can happen using a TRX strap.

TRX Training Center is now the "global epicenter" for all things TRX training. The studio welcomes athletes of all backgrounds and fitness levels, even those who are new to working out and new to the TRX method.

"It started off as a space for research and training our staff, and something we looked at as an internal tool," Hetrick said. "But over the years more people came by and asked if they could join in classes and it got us thinking about creating training centers and gym models."

Sunday through Saturday, TRX Training Center members can attend classes at the studio. Classes include TRX 415 Bootcamp, a 50-minute class that highlights high-intensity intervals using the TRX straps. TRX Strong is another class, focusing on strength training and using bodyweight to sculpt lean muscle. Also on the schedule is TRX Sweat. In this class, students will run, jump rope and experience "intense cardio challenges."

"The studio is like no other studio in the Bay Area and you can't compare our members to anyone else," Kayla D'Alonzo, Operations Manager, said. "Our members are part of the TRX family and when they come in, they are ready to workout. When our instructors and front desk staff brings the energy the class turns up in [a] matter of seconds."

Part of what makes TRX suspension training so effective, according to D'Alonzo, is that you can't hide weakness from the strap. This type of training forces each person to work on those weaknesses throughout the class and become stronger.

"With the different classes we offer, everyone has their favorites and can push themselves to the limit," D'Alonzo said. "Members can challenge themselves with some of the workouts that may not be some of their strong points. All workouts have a combination of both smart and hard, and when you combine those two together, you get a sustained workout."

There are several membership options for those who want to train at TRX Training Center. From class packages to monthly and annual memberships, TRX Training Center has a membership for everyone. To learn more about TRX Training Center, visit
