Pro Resistance Bands
Dick Hartzell invented the resistance band. Louie Simmons put it on the barbell. Every band here is the same layered-latex build that helped set world records in the original gym — matched in pairs, sold as a complete dynamic-effort set.

Continuous-loop, layered-latex bands — not welded rubber. Each pair is tension-matched so both sides pull even off the floor. Rated for dynamic-effort squats and pulls, banded bench, pull-up assistance, prehab, and traveling workouts.
Band comparison
| Band | Resistance | Common use |
|---|---|---|
| Micro | 5–35 lbs | Pull-apart, prehab |
| Mini | 10–50 lbs | Speed bench |
| Light | 25–80 lbs | Squat / DL speed work |
| Average | 50–120 lbs | Heavy dynamic effort |
| Strong | 65–200 lbs | Max-effort overload |
Not sure? The Pro Set (Light → Average) covers 90% of Conjugate programming.
Fifth order of bands for my weight room. Westside bands are great quality and matched tensions actually matter — both sides pull even.
The Pro Set is exactly what I needed for speed squats. Chart made it easy to pick.
Layered latex feels bombproof compared to the cheap welded bands I've snapped before.
