Oh Right - yeah i did look at the section for hamstrings and they were a little limited definately. I really wouldn't be suprised if that's a big part of it. Thanks for reminding me Scrap.

The test they had in this book for the hamstrings was lying down flat and you're supposed to get your leg to be able to rise to a 90 degree angle - I can almost do it but not quite.

I don't really understand how they use the seated leg extension one as a test for the quads because i think they're contracting in that movement but that is what the book clearly states. I guess they say functional assessment not quadricep length - but they recommend stretching the quads.

Interestingly they link tight quads to lower back and knee pain so whether they're the cause of this limitation or not i might get into stretching them as a preventative thing since I know i'll be prone to both of those problems.

Still you're ight and it doesn't completely make sense so I googled it to see what tests were online for the Quads and I found a different looking one for quadricep length in the diagrams of this article:

There are all sorts of tests i haven't heard of in here - I'll have to read this one now!
