My therabandits have been deceiving me.
I've been using them for rotator cuff physiotherapy exercises. I bought some cheapo ones from that big uk high street sports shop. They are the flat type, 15cm width, not a double/tubular layer, come in a 3 pack, purple = easy, light blue = moderate, lime green =hard.
I stuck with the easy one for a few weeks to get accustomed to them, + as i even struggled on the moderates to begin with, but after 4 months seem to have progressed to be able to use the hardest band for most of my physio routine, so i was getting good use out of them, especially after reaching a climbing goal through their use.
A few weeks ago i even snapped the moderate one, so tied a knot in it and continued to use it (slightly harder now because it's shortened). The next week i snapped the hardest one too! Golly, i am so strong now, i thought, + made some incredible hulk noises to my cat. He wasn't too scared though, as usual.
I have just bought a new set, of the same brand, and am really disappointed to find that the easiest one seems hard, i can only just do the moderate one, and i can't touch the hardest one!
Perhaps the quality control department is not so good there, and they come off the production line with untested + unequal resistance from one batch to another?
Or, more likely they lose elasticity over a few months use and get progressively easier, and you don't realise how much, until you buy new ones!
Has anyone had this problem too? I suppose it's to be expected from elastic bands. I'd be especially keen to know if you bought the genuine article brand of Therabands, and how long they last, (please state how much you used them, daily, twice daily, less, etc) before you needed new ones, and also how difficult did new ones feel compared to your old ones.
I have some latex tubular ones too, about 10mm in diameter, that i'm going to start working with. Perhaps they will prove to be more reliable.
I suppose the only way to know the resistance is the same, would be to use some weight machine down the gym, but that would be less accessible, and couldn't be used whilst having breakfast, getting ready for work, etc, thus risking not being able to maintain the required frequent use.
I got to a point where my shoulder seemed to be getting ok, but it' been getting worse again recently. Possibly caused by using therabands with progressively less resistance? (unknown to me at that time), but more likely from trying routes that had some hard shouldery gaston moves.
