It was in the 1980’s when Coach Dick Hartzell introduced 41” resistance bands into strength training. For nearly 40 years, this was the only size available. That all changed in 2020 when we released 32” resistance bands. The 32” bands were specifically brought in for banded resistance training and for users who needed less slack in their bands. Generally, users under the height of about 5’10”.
After the release of the 32” bands, we immediately received requests for a band that was in between the 32” and 41” length. Over the past 18 months we have been hard at work testing different lengths, widths and thicknesses. We are happy to report that these bands will be the same thickness and width as our 32" and 41" bands. This consistency will hopefully make for an easy transition from one length band to another.
What can you expect:
- 37” in length, 15 Continuous Layers
- Same thicknesses (4.5mm) as our 41” and 32” bands
- Same colors as our 41” and 32” bands (Except for #5 which is traditionally black, is now gray)
- Different logo design and color
- Same high-quality latex
37" BAND TENSIONS FOR FOOTPLATES (lbs per inch)
To use this table, start by measuring how far the band stretches — this is the difference between the starting and ending positions. For example, if the band starts at 8" (point of first tension for double layer 37" bands) and ends at 34", it has stretched 26". Multiply that stretch distance (26") by the band's pounds-per-inch (PPI) rating to calculate the tension. If there’s no stretch, there’s no tension.
For example, if you're deadlifting with a 37" #3 band that is doubled under a footplate and has a PPI rating of 6.32, you would calculate the tension as:
6.32 × 26 = 164.32 lbs of tension.

Band Length Recommendations
Still struggling to determine which band length is right for you?
Below are three different user heights and their preferred band lengths for a variety of movements.
User 1: Height 5'2"

- Chest Press: 32”
- Tricep Press: 32”
- Overhead Press: 37” or 41”
- Front Squat: 37”
- Deadlift: 32”
- Bicep Curl: 32”
- Bent Row: 32”
- Calf Raise: 32”
User 2: Height 5'9"

- Chest Press: 32”
- Tricep Press: 32”
- Overhead Press: 37” or 41”
- Front Squat: 37”
- Deadlift: 32”
- Bicep Curl: 37”
- Bent Row: 37”
- Calf Raise: 37”
User 3: Height 6'
Image: User 3 curling a 37" #3 Band
- Chest Press: 32”
- Tricep Press: 32”
- Overhead Press: 41”
- Front Squat: 41"
- Deadlift: 32”
- Bicep Curl: 37”
- Bent Row: 37”
- Calf Raise: 37”
How much tension does each band offer?
We conducted multiple tests to determine the pounds per inch each band produces (across all sizes and lengths). The data table to the left shows the pounds per inch for the first inch of tension.
To use this table, measure your starting distance and multiply it by the band's pounds per inch to find your starting tension (which could be zero if there is no tension). Then, measure the ending distance and multiply it by the pounds per inch to find the ending tension.
For example, if you're deadlifting with a Green #4 37" band double-looped under the footplate, with a starting position at 12" (mid-shin) and an ending position at 31" (standing with hands by your side), and the pounds per inch for the green 37" band is approximately 9.83 lbs, the starting tension would be about 117.96 lbs, and the ending tension would be about 304.73 lbs.
Why 37" Bands?
The 32" Bands were a massive hit with users under 5'10" for most movements. However, some users found themselves desiring a Band length in between the 32" & 41".
The 37" bands were specifically developed for those looking for the "just right" size, keeping you under tension throughout your full range of motion.
Band Tension Comparison
- Bands can safely stretch 2.5x their length
- 32" x 2.5 = 80" safe max stretch
- 37" x 2.5 = 90" safe max stretch
- 41" x 2.5 = 100" safe max stretch
- Shorter bands will give you a higher tension for the same movement.
Less Slack = Greater Gains
We created 37" Bands to provide optimal time under tension throughout your entire range-of-motion.
Keeping tension on the bands keeps your muscles engaged, producing better results & greater gains.
Exercise Anywhere
Resistance bands are the ultimate travel fitness tool.
Bands are light and compact allowing you to train anywhere.
Endless Uses
From stretching and mobility to bodybuilding or powerlifting, resistance bands can be your primary training source or a great supplement to your regular routine.
Do you plan on using your bands with a band board training system? Consider purchasing a Band Guard to protect and prolong the life of your bands.
WHAT MAKES OUR BANDS DIFFERENT?
SRI LANKA
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.
ALL ABOUT THE LAYERS
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%.
PROTECTIVE COATING
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.
