Band tension question

[natural-mike]

Can someone give me some idea of what the band tension (in pounds) is for the following:


1 mini band regular, doubled, choked = lets say for situps and stuff


2 mini bands regular, doubled, choked = lets say for benching and for squatting (i.e. one band on each side of the barbell)


Same as above for :

1 average band (green)

2 average bands (greens)

And if your feeling especially chatty go ahead and tell me about the Blue bands too.


Thanks,

I tried to search but got mixed info which was not specific .

As you can see I'm not so band savvy.

Thanks peeps,
Mike

Here is what i know
with a bar 62" off the ground my pink bands add an additional
58 pounds to the bar

at the same height the green bands add an additional 87 pounds to the bar.

at the same height with the pink and green bands both attached to the bar it adds an additional 143 pounds

the same set up at 48 inches adds 79 pounds

" " " at 43 inches adss 40 pounds

" " " at 38 inches adds 5 pounds

good luck

Found this article on Elitefts.com i figured it might help w/ some band tension questions.....

".....

Anyhow here's my band tension findings . . .

Tension Values of Jump-Stretch bands with different cinching and
anchoring systems.

I spent the better part of a Winter day doing this - so I hope ya'all
appreciate it!

"Slack" measures distance from nearest part of anchor to end of band
held to furthest length.

"Single-cinch" means one end or loop fed through another loop around
an anchor,

"Double-cinched" means one loop feed through other loop twice around
anchor. Third option is self-explanatory.

"Double-looped" refers to draping band over bar so that the two loops
of each band are used as a single suspension point.

The meaurees after the slack tell you how much extra stretch from the
slack point (=0) the poundage gives you . . . i.e. if 45 lbs stretchs
a band 4" then 45 lbs of pressure will stretch it 4". In the case of
the double-looped anchorings the use of four loops to hold the barbell
took up enough band so that the bottom of the barbell was actually one
inch higher than the bands hanging slack - hence the "-1.0" for the 45
lb measure.

The bands were looped around the outside of the barbell collar in
every case. I assume that you would place weights on the outside of
the band as you add them.



Blue Bands - (single-cinched)
Slack = 33.0"
w/ 45 bb = 1.5"
w/ 135 = 15.25"
185 = 27.5"

Blue Bands - (double cinched)
Slack = 27"
w/ 45 bb = 1.5"
w/ 135 = 12.5"
185 = 22.5"
205 = 28"

Blue Bands - (single-cinched around two dumbells)
Slack = 19"
w/ 45 bb =2.75"
w/ 135 = 12.75"
185 = 21.0"
205 = 24.0"
235 = 30.0"

Blue Bands - (double looped)
Slack = 18"
w/ 45 bb = -1" (less than slack)
w/ 135 = 2"
185 = 4"
205 = 5.25"
235 = 6.5"

Green Bands - (single-cinched)
Slack = 32.5"
w/ 45 bb = 3.0"
95 = 15.0"
115 = 21.5"
125 = 25.0"
w/ 135 = 28.5"

Green Bands - (double cinched)
Slack = 25.0"
w/ 45 bb = 2.75"
95 = 11.5"
115 = 17.75"
125 = 22.5"
w/ 135 = 23.5"

Green Bands - (single-cinched around two dumbells)
Slack = 18.5"
w/ 45 bb = 2.25"
w/ 135 = 16.5"
185 = 28.5"
205 = 34.5"
235 = 41.5"

Green Bands - (double looped)
Slack = 18"
w/ 45 bb = -1.0 (less than slack)
w/ 135 =2"
185 = 5.5"
205 = 7.25"
235 = 10"

Pink Bands - (single-cinched)
Slack = 35"
w/ 45 bb = 7.0"
65 = 13.75"
85 = 22.5"
95 = 28.25"

Pink Bands - (double cinched)
Slack = 29.5"
w/ 45 bb = 5"
65 = 10.5"
85 = 17.5"
95 = 22.5"
105 = 26.75"

Pink Bands - (single-cinched around two dumbells)
Slack = 20.5"
w/ 45 bb = 6.0"
95 = 20"
w/ 135 = 32.5"


Pink Bands - (double looped)
Slack = 18"
w/ 45 bb = -0.5 (less than slack value)
w/ 135 = 5.0"
185 = 11.5"
235 = 19.5"
235

I also measured the minis -

New Greens or New Blues should be equal and should be measured
double-lopped

Slack = 18.5"
45 = 3.75"
65 = 8.25"
85 = 14.0"
95 = 18.5"

I have learned that a heavily-used (for over a year) miniband will
stretch 50% more than its new counterpart. i.e. 95 pounds will
stretch 27" instead of 18.5"

Wow, that guy had a lot of time on his hands. Mike, doubles minis for me give about 35 lbs at bottom and 70 at the top of my bench, give or take five pounds. If you set up the minis so there's about 0-5 lbs tension at your chest, then there will be about 20-25 lbs at your lockout. And if you choke the band two or three more times from that setup, you can get it up to about 15-20 at chest and 35-40 at lockout.

I don't have the other bands so I can't help you there.

 

[GRIMMER]

All of these numbers should take into acount individuals lockouts grips and ancoring points. so a standard deviation of say + or - 15lbs at each point. all measurments were taken with a standard DB as ancor.

Minis Doubled
50 at chest
80 at lockout

Average
looped
35 at lockout
no tention at chest
Doubled
170 at lockout
115 at chest

Greens or mediums
looped
50 at lockout
no tention at chest

doubled
280 at lockout
didn't measure chest as i will never need this much tention

Floor presses
Greens or mediums
110 at lockout

Revers band bench from 7' rack looped Greens or mediums
-65 at lockout
-95 at chest.

Hope this helps

man... if only i had a dime for every time the band tension question was asked.


the real answer: who cares.

Band tension does NOT translate to real weight. You can't make an assumption about carryover based on how much tension there is especially when the tension is different depending on height, setup, etc.

Just keep your PRs according to band strength and looping.

 

[DBCooper]

I agree completely with IrishPower.The strongest may not use the most band, just like on all movements with weight.

 

[latinus_spicticus]

From the Jumpstretch website.

These tensions are listed when the bands are stretched to 6 feet. Hence, if you are 6 ft tall, and are squatting, the poundages are similar to what you would experience if you were using them.

Minis- 25lbs per band when stretched to 6'

Light- 50lbs per band '' '' ''

Average- 75lbs '' '' ''

Strong-100lbs '' ''

The jumpstretch.com website also has some other info on the band tensions. I do kind of have a hard time believing that the average band is only 3x as strong as a mini-- the strong is 5 times as thick as a mini, for crying out loud. I don't have the strong bands, though. But I do have all the others, and the average feel about 4-5 times stronger than the minis, although the minis seem to wear out fast as hell.

Like Irish said, though, none of these measurements take into account the individual setups, lockout/starting points, ranges of motion, attatchment methods, etc. that are specific to each individual case.

I would like to get a jumpstretch deadlift base, too. I could do deadlifts/rows/whatever with lots of tension w/o worrying about anchoring the bands. Could do some damage with that.

Natural mike i am like you and i liek to knwo what the tension is. We actually used a bench, and blocks to build a base up and measure various tensions. Single looped, double On chest, at lockout ETC. I like to knwo so when i do look back on a pre meet trainig regimen i can say "well when i benched 585 i had 110 at lockout, and when i did 600 i had 125, 625 i had 150 ETC". Its not important but i know what my body is doing before everymeet. And when my trainig is closely monitored i can always re set the bands excatly the way they were and go for a PR. And i can actually tell what i will bench (around) by just my training alone off boards and bands. Same with squats.

But like i mentioned months ago here, i use so much band tension sometimes a 350lb bencher would not be able to lockout the bar alone. So since i am addicted to bands i too like to know about how much there is at the bottom and top. Its not important but if its driving you crazy (like it did me) weigh it out and write them down. Make sure you got a couple hours cause if you got lots of bands the combos, choked, suspended, double looped , single, triple, 2 bands, 3 bands on each side the list goes on. It can take awhile!

 

[natural-mike]

Thanks a ton guys, I'm sure we have all questioned this.

I guess after all this imput, I fall in-between plftrjay and Irish, , in other words, I care a little, but not enough, I'll just record which band, which setup (doubled, looped, choked etc.) and the bar weight. My only real concern was the ratio's of bands to raw weight, I would like to keep that in a satisfactory range.

Thanks again,
Mike
