There may be 2 or more that are similar and you may train more than 1 but just post what you belive to be the most important.
An eccentric contraction. Kneel on the floor, have a partner hold the back of your feet, fall to the floor as slow as possible, when you have masterd this process attempt to lift yourself back up. Of course keeping a straight posture is important.
This exercise is guaranteed to leave you sore a few days later 
Not sure if this movement carries a specific name though. Any ideas?
KC, the movement you are describing is a Manual GHR, or a Natural GHR, depending on who you ask. I used to do them a while back and loved the movement.
And to the OP, I personally find high intensity EMS STIM sessions on the hamstrings to be one of the most beneficial things for strength. If you have an EMS device, try it.

Great article to consider the reasons for exercise.
why do you feel ems is great for hammy strength.
I like EMS for hamstring strength because I used it for about a month and during that time I went from not being able to do a natural GHR, to being able to do 5-6 full unassisted reps. Then, a little while later, I dumped all strength work for a little over a month and used EMS on my hamstrings the whole time again and when I came back to the weight room I hit 11 full unassisted reps in the natural GHR.
Since then, my EMS use has been spotty at best. Mostly because I have to shave my legs to get the full effect from it and the fact that it hurts like hell. Ever since I stopped using it regularly though, I haven’t been able to come near my old peak on the natural GHR.
I don’t know if everyone experiences strength increases like this, but that’s how it happened in my experience.
If only the EMS devices weren’t so inconvenient, I’d use them every day.
Well get a Compex or other user-friendly/convenient unit.
Yeah, I must admit I am not so up to date on the best units, I’ll look in to it.
I have a Compex 500 sport…EMS as good as it is is very time consuming…the set up is very straight forward but the programs last for 30mins + including the warm up pulsing. If you’re a full time athlete with time on their hands it can work very well…i train in the evenings and work in the daytime…by the time I come home from a session (sometimes gone 11pm) the last thing on my mind is getting hooked up to my EMS machine.
Back on subject - I think some benificial hamsting work (coming from someone who’s pulled both) Is definately hamstring curls on the machine - NOT the one where you’re upright…the one laying on your front. - Single and double leg. Also Double leg up and single leg down slowly. Another exercise that helped me was Swiss ball single and double leg ham roll in’s and outs. - place both feet on ball,raise hips,roll the swiss ball out with both legs and bring back with one. Keep hips elevated through the movement.
Sorry for the off-topic but how long is the warmup pulsing?
I agree about the ham rolls on the swiss ball. good exercise three.
wheres sprinting on that list 
:D?
A general perception of BB’ers is that they love ‘sprinters’ hamstrings. When you look at BB’ers none ever look like they have a ‘sprinters’ set of hamstrings!
There must be something in sprinting for building hamstrings… :rolleyes:
from this article

I haven’t seen a sprinter with hammies like this
Interesting back squat is voted highly since it seems to be more glute and quad dominant than ham.
I would also have thought back extension would be voted more since it is the alternative to reverse hyper that most gyms do not have.
The most important ham exercises for sprinters must surely extend the hip whilst the knee is in no more than slight flexion. It would also be an advantage to contract the hip through extension whilst the knee is contracting statically or flexing slightly; this would force the full length of the hams to contract together as at the end of the swing phase and on initial foot placement in sprinting. To add to this it seems that ham injuries often occur at the end of the swing phase when the knee and hip contract together.
If soreness is anything to go by, back extension and romanian dead lift make my hams more sore than anything other than maybe sprinting itself.
They’re good, but you need to be real strong in the hams to get any benefit (maybe called Russian hypers???)…
I think stiff legged deadlifts might be the single best hammie exercise. Powerlifters and weightlifters I’ve talked to agree.
Charlie what do you think?
my favourites are
one legged RDL’s
and
eccentric leg curls (up with 2 down with 1 for a 4sec count)
It lasts for 4 mins Mort.
being sore is not a indicator that an
excercise is beneficial.
The rules not so rigid as that james and in this case it relates greatly to the soreness I receive post sprinting!
