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.
