One Bandbell Bar
That Made It
Possible.

Jim Seitzer was the first official member of Westside Barbell. He met Louie Simmons in 1976, trained beside him through the basement years, the garage years, and the first commercial space. Won Mr. USA. Hit an Elite 1,824-pound powerlifting total. Then his shoulder gave out. So he built a bar that let him keep training. Every Bandbell ever made started with that prototype, and now they're stocked and shipped through the gym where it all began.

The Lineup

Pick Your First Bar.

Every Bandbell bar runs on the same principle. The differences are in capacity, length, and what kind of loading the bar's built to take. Start with the one that fits your gym.

The Origin

From a Broken Shoulder
to a Better Bar.

"I started with a broomstick. Hung resistance bands off each end. Hooked kettlebells to the bands. The kettlebells swung as I pressed. The bar wobbled. The pressing pain disappeared."

— Jim Seitzer, Founder

Jim came to Ohio State as a gymnastics scholarship kid. Lettered three years on the rings. Two weeks before the Big Ten meet his junior year, he tore his bicep doing straight-arm shoots. The injury never healed. Senior year, he was finished as a gymnast.

He started lifting weights to rehab the arm, ended up at the OSU weightlifting club in the southwest corner of the bell tower. One Saturday in June 1976, a guy with hair down to his shoulders walked in and started benching what looked like everything in the gym. Jim worked up the nerve to ask him for help. The guy said come by my place next Saturday. That guy was Louie Simmons.

Jim showed up at 590 Larkim the following week. Five guys, a basement, no commercial gyms anywhere in Columbus. They squatted heavy. They figured it out as they went. Jim was the first official Westside member. He stayed through the basement years, the garage years, and the move to Briggs Road. He won Mr. USA. He pulled an Elite 1,824 powerlifting total. He was the only national-level bodybuilder in America to do both.

Decades of squatting 500-plus pounds wears a body down. By his fifties, Jim's shoulders were finished. He couldn't bench an empty bar without pain. Most lifters quit at that point. Jim went into the garage and started experimenting. A broomstick. Bands hooked to each end. Kettlebells dangling off the bands. The first time he benched it, the kettlebells swung, the bar wobbled, and the pain was gone.

That ugly first prototype is now in gyms in over twenty countries. Jim spent the next two decades refining it into the Earthquake Bar, the RhinoFlex, and the rest of the lineup. Every bar he makes solves the same problem he started with: how do you keep loading the body when conventional bars are breaking it down?

Hear It From Jim

The First Member of Westside Barbell.

Tom Barry sat down with Jim for the inaugural Westside Barbell podcast. Forty-five minutes on meeting Louie, the basement years, the reverse hyper origin story, and how the first Bandbell bar got built.

Why a Different Bar

What's Wrong With a Regular Barbell?

Nothing. A regular barbell is the king of building strength. But it has blind spots. The Bandbell bar fills them. Side by side, here's what changes the moment you swap one for the other.

The bar holds still. Your body braces against a known load. Big primary muscles do the work. Small stabilizers loaf along for the ride.

Bandbell BarWobbles. Bounces. Forces you to control it.

Weight hangs off bands and oscillates. The bar moves in three directions you didn't ask for. Stabilizers, rotator cuff, and deep core have to fire just to keep it tracking.

Heavy compressive load through stiff joints is how most lifters end up with bad shoulders, sore elbows, and surgeon's appointments.

Bandbell BarPumps blood into joints without crushing them.

Oscillation drives circulation through the joint capsule with a fraction of the compressive cost. Lifters with shot shoulders can press again. Sore elbows recover between sessions.

A barbell trains you to brace against static load. That's a specific skill. It doesn't carry over to the chaos of sport, life, or anything that moves back at you.

Bandbell BarTrains your reflexes, not just your muscles.

Your nervous system gets a flood of feedback every rep. Bio-motor control sharpens. Reaction time improves. You build the kind of strength that holds up when the load is unpredictable.

Pain. Plateau. Surgery. The conventional answer is to back off until the body is "ready" again. Most lifters never come back.

Bandbell BarYou stay training. Year after year.

Jim built it because he refused to stop lifting. The whole point of the bar is to keep loading the body productively for the next forty years, not just the next six months.

Who Needs One

Every Gym. Every Setting. Same Bar.

The Bandbell isn't a niche piece of equipment for one type of lifter. It solves a different problem in each environment, but it earns its rack space in all of them.

Your starting QB can't afford a tweaked shoulder in week six. The Bandbell builds rotator cuff, scap stability, and pressing strength without piling stress on joints already taking a beating from the sport.

Teenagers come into the weight room with weak stabilizers and big egos. The Bandbell humbles them at light loads and teaches the small muscles to fire before they ever load a real bar. Fewer injuries, better movers.

The gap between rehab exercises and real lifting is where most patients quit. The Bandbell fills it. Light enough for rotator cuff rehab, loadable enough to take a patient back to a real bench press.

You're forty, the kids are at practice, you've got an hour. You don't have a massage therapist or a training staff. The Bandbell lets you train hard and still pick up a toddler the next morning.

How It Actually Works

Three Things Happen the Second You Lift It.

You don't need a degree in biomechanics to understand why this bar works. Here it is in plain English.

The Bar Wobbles

Weight is hanging off bands, not clamped to the bar. Every rep, the load swings in directions you didn't plan for. That's the stimulus.

Your Small Muscles Wake Up

To keep the bar from going sideways, the rotator cuff, scapular stabilizers, and deep core fire on every inch of the rep. Muscles that loaf during a normal bench have to work for their lunch.

Your Joints Get Fed, Not Crushed

Oscillation pulls fluid through the joint capsule. Translation: you finish the set with more blood in the shoulder and less wear on the cartilage. That's why it works for both heavy lifters and rehab patients.

Athlete Endorsement
"Strong stabilizers, low risk of injury, increased muscle activation at light and heavy weights. As an IFBB Pro and 2x Olympian, I made it here in seven years using the Earthquake Bar and RhinoFlex bars almost exclusively. The growth just follows."
