NEW! Myprotein Resistance Bands

Good to see MP have got some bands in - great training tool.
But what does this mean?
Available resistances:
2-16 kg (red band)
11-36 kg (purple band)
23-54 kg (green band)
27-68 kg (blue band)
32-79 kg (orange band)
Surely the more you stretch it, the more the resistance!

The bands I bought last time are rated like this... which has much more meaning

% Stretch #1 Band #2 Band #3 Band #4 Band #5 Band
(lbs) (lbs) (lbs) (lbs) (lbs)
100 8.0 16.0 20.0 31.0 45.0
200 11.0 19.0 25.0 40.0 58.0
300 14.0 24.0 33.0 48.5 74.0

Cool eh?
he bands I bought lat time are rated like this

Im assuming its the increase in added resistance from the bottom of a movement to the top?

hodi, what you said doesn't make good sense.....
Which movement? some will stretch the bands more than others dependiong on the equipment used or the hieght of the person. Also sometimes the band will be doubled.

From zero displacement to full displacement of the band.

Displacing the band just a little by pulling it will give the lower limit of the force (For instance 2kg.) Then extending the band to full displacement will lead to a 16kg equivalent force. Displacements within this range will lead to a force between the two limits. You can calculate these percentages quite easily.

MP is clearly a company aimed at intellectuals Forget giving you the information; you need to work it out yourself lol.

That is all well and good if you know what the full displacement is.
Is it an increase of 100%, 200% or 300% of original length or something else?
The spectrum of resistance is always from zero until the band snaps, so the minimum resistance must be zero!
If you get a resistance of 2Kg I'll stretch it half as much and get a resistance of 1Kg
I'm assuming here that resistance and length have a linear relationship, ie. Hook's Law (Physics).
Of course, being an interlectual, you'd know that lol.

geek alert! hahahaha

One would wish that rubber bands obeyed Hookes' law but unfortunately they do not (They do under limited conditions actually). They undergo hysteresis and produce what it known as a hysteresis loop. Hookes' law main application is springs.

MP should add this conversation to the product description lol.

Only on an MP forum could you get an in-depth, all-encompassing, technical discussion of how much grunt it takes to stretch a rubber band.




I love it!

What MJ said!

I wouldn't sweat the small stuff when your using bands. The increasing resistance allows for a need in acceleration throughout the entire movement. More acceleration means more force applied to the bar. More force results in more fast twitch fibre recruitment. Start on the lightest band, then just as you would increase weight on the bar, change up through the bands as you progress through your program. Sometimes its not the load on the bar that counts, its the force that's applied.

The bands are sold in pairs so is this the resistance of both bands together or the resistance of each individual band?

Per band

They are such a useful tool. I use them on bench press, squats, front squats, zercher squats (my favourite). I also used them on biceps curl and close grip bench press, in my challenge with Men's Health fashion editor Dan Rookwood
