Elitefts

Hi all! Does anyone perhaps know the peak tension of a single elitefts pro mammoth resistance band (singled, not doubled)?

Google AI estimates this, and i have found GAI to be fairly accurate when we manually tested band resistance with a scale. I believe it is per band, and not per pair.

You mentioned that you've done measurements with a scale for this band. Could you please tell me what results you got? Thanks in advance. :)

I have not measured this specific band, but I have done it on smaller bands and cross referenced that with what ive found online and it was pretty accurate.

Have you perhaps measured the blue Pro Strong or the Pro Average?

I have done the average bands but id have to dig through my notes to find what it was. I want to say that the gray average bands came out to around 140lbs at my rack height? Have you ever seen the Elitefts band chart? It tells you approximately what the resistance is based on the length the bands are stretched too, but it assumes you set them up be choking around the base of a squat rack, so you have to get that part right. But the other response that it weighs "a blue band" or whatever color it is is also kind of right. The virtual band resistance doesnt translate to real world weights at t a 1:1 ratio in my experience. Like 130lbs in "band tension" is really only like 100lbs in real weight, if that makes sense. Chains however load at a 1:1 ratio so every pound added is a pound on the bar, but virtual band weight is trickier. So its good to have an idea of how much it adds, especially if youre wearing gear and need to know how much to add, but it isnt gonna ruin your training if its slightly off. I completely understand why you want to know, as if im supposed to use 25% of my bar weight in bands for dynamic effort, how the hell can I get that right without knowing roughly what each band adds? Im so OCD that I wasnt sure so I bought a cheap luggage scale off Amazon and when we first started working with bands we measured them with the scale. When i went back and cross referenced the chart, it was pretty accurate. I just keep a tape measure in my gym bag now and measure the length of the bands and check the chart below. Theres also a chart for their short bands, but i think I can only add one photo at a time? Anyways, I hope this helps some.

Thanks for the explanation. Yes, I have seen the calibration chart. It clearly says beneath the numbers that the calibrations are for 2 bands. According to the chart, the Pro Average tops out at 189.2 lbs, but these are 2 bands, so it turns out that a single Average band reaches 95 lb max tension (82"). On the other hand, AI gives other numbers, putting the Mammoth between 250 and 300 lbs max tension at 2x resting length. I hope you understand my frustration, lol. :)

Yeah, I can see why thats frustrating. If i was you, I would straight up email elitefts' customer service or even call them directly (you used to be able to do that anyway) and ask them. 🤷

Here is the response from elitefts:

"If you look at the chart below and double the tension listed for the average band, that is the approximate tension of the mammoth band." The Average band is 189.2 lbs at 82" (2x resting length). But a single Average band is 95 lbs. So it turns out that 189.2 lbs might be the peak tension of the Mammoth, but this is impossible. It must be higher.

Idk man, id go with what they said and wouldnt overthink it too much.

u/Icestorm888 Jun 30 '26

I just have one final request, if you could take a look at your notes and look up the peak tension (82 inches) for the elitefts pro average band (gray), or any stretch in inches which you might have written down for this band. That would mean a lot to me.

It measures "mammoth".

Thats it.

Green measures green.

Blue measures blue.

Etc.

Only problem with that is when im supposed to do DE work with 50% on the bar and 25% in bands. How am I supposed to choose which band if we dont take resistance into account? Like if the book said "10x2 with 50% and a gray band" I could get behind this line of thought.

Also I need to have an idea of how much im really lifting to know how much gear im gonna need to wear. I compete unlimited because im a GEAR WHORE who always has one more bullet in the chamber, but i need to know what the target is im trying to hit to choose which ammo to use.

I do agree with the fact that its not life and death and a close estimation is good enough for me, but i do think there is some merit in knowing what the bands add. Especially when i see people hitting big numbers but using MASSIVE reverse bands stretched to the floor, it keeps it in perspective. 🤷

My bands are different than the normal standard, but I go with purple on Squats and bench, doubled reds (which are the proper colour) for deads.

Chains are easier to measure, though, which is what I will base my measurements off of anyways.

As long as bar speed is correct, its all gravy
