Jefferson curls

Can anyone help? I'm 'curling' from my T spine and can't flatten my chest against my legs. I can get all the way down with straight legs as you can see, But I'm making an "n" shape, instead of an "l" shape  -_-. It sucks... any suggestions? 

Hey Alli, simply your restriction on the hamstring it is so big that you finish compensating on the upper spine. Are you following the front split stretch series?

That makes sense.

I am doing foundations, but am not following the front splits programme as a) I do not have an extra 1.5 hours free anywhere in the week and b) I cannot afford it. However, I am working towards a front split using other methods which are having great results. Believe it or not, this image of my shocking form is actually a vast improvement from a couple of months ago!! Which leads me to my next question; do you think I should just focus on those guitar hamstrings of mine and stop Jefferson Curls, or do you think that the Jefferson curls themselves might be a good way of acquiring one.. Make sense? Without blasting my back out preferably.

Thank you :-) 

Hey Alli,

As long as your back is healthy and pain-free, working slowly and steadily on the Jefferson Curl will help your hamstrings loosen up. 

Thanks guys :-)
