Care Guide
  • Storage: Keep out of direct sunlight, humid environments or excessively hot or cold temperatures.
  • Cleaning: Yes, bands can be hand washed. Hand wash with warm water and a non-abrasive cleaning solution. Hang to dry. (Ex. Dawn dish soap).
  • Caution: Avoid direct contact with knurling, asphalt, concrete, or any abrasive surface. If using your band on any of these or a board system, we recommend a protective barrier like our Band Guard, a towel or old shirt. This helps maximize the durability and life of your band.
  • Life Span: Based on average use -which we assume to be 1-hr of use 3 times per week- bands should last 12-18 months in residential settings and 6-9 months in commercial settings.
  • Normal Wear & Tear: Our bands are one continuous piece of latex made through a proprietary layering process with a total of 15 layers. Over time the bands may begin to peel or show other signs of use. This is normal and does not affect the integrity or application of bands when minor. If peeling gets worse, it may be a sign that your band is aging and may be due for a replacement.

The #0 Orange band provides our lowest level of resistance and is great for light stretching, warming up, rehabilitation and shoulder activation.

Bands #1 & #2 are best for general conditioning, rehabilitation, stretching, jumping, speed training, aerobics, and for lifters as assistance for the upper body to increase the resistance for bicep and triceps.

Either band is great for beginners and light weightlifters. Both can be used to safely increase the intensity of a workout without adding additional weights to a bar. For the stronger lifter, they will add considerable resistance to bicep and tricep exercises.

Bands #3 & #4 can be used by stronger benchers, and with exercises involving the lower body, calves, quads, hamstring and glutes.

Large and X-Large Bands (#5 & 6) are usually used for obtaining maximum resistance with squats, deadlifts, leg presses and shrugs.

Top Quality | Fair Trade | Sustainable

Our manufacturing facility has been a top producer of natural rubber latex resistance bands since 1947.

Raw Materials are sourced locally through heavily regulated, sustainable and eco-friendly farming. 

Sri Lanka is also free from child labor.

Premium raw materials are the foundation of our bands, but our proprietary manufacturing process is what makes them some of the best bands in the world.


The seam on our bands is not a mistake or defect. Actually, this is one way you can tell you have a quality band!
How our bands are made:
Our bands are made through a continuous layering process with 15 total layers. The 15 layers from one piece of latex gives the band a seam on the inside and outside. Our manufacturing process helps maximize durability, elasticity and tension consistency. 

The consistent tension curve throughout your ROM is the best way to feel the difference between a high and low quality band. Lower quality bands have a force curve that typically flattens out when stretched beyond 70%.


Resistance bands are basically big, rubber bands. You have probably noticed that old rubber bands it will start to dry-rot.

To prevent dry-rot and maintain elasticity, a natural and non-toxic protective coating is added to each band. Natural Rubber Latex needs additional components to maintain material stability and elasticity. Even though it is natural and non-toxic, this could irritate skin if you are allergic to, or have a latex sensitivity.

Can bands be washed to minimize this?

Yes. This can be minimized by washing the band with warm soapy water. Air dry or pat dry with a clean towel.

Band Review

I am extremely happy with the bands. I have bands fro other companies and feel the resistance level of these bands is far superior

Andrew Margolies

Items were sent and delivered quickly. Great product works great with X3 system

Strong bands and a high quality

I've been using the 41" bands for a few weeks. They are definitely a very high quality band and provide plenty of tension and I get good workouts from them. Overall very happy with the purchase.

Best bands ever!!!

I ordered the complete stack and wow are these bands strong and quality made. Even the lightest band is strong and great for stretching and warming up before your workout, I have several bands from other companies but these Serious Steel bands are the absolute best I’ve used. I highly recommend them to resistance band users. Shipping was fast and smooth.

Great for deadlifts

These bands are great for deadlifts, and doubling them over means that you get resistance much lower in the movement than you can get with other bands.
