Pull throughs from low cable really concentrating on a good stretch and then strong glute contraction at the top. (Can use variety of grips with the rope so should find a comfortable one)
hamstring curl machine, using 1 and half rep technique. Curl in, lower half way, pause and then curl in again, lower fully. That's 1 rep, concentrate on really controlling the weight. Sets of 10-12.
Lower Back machine or raises depending on what's available.
I've really neglected deadlifts for about 5 months, but instead have done the above, I've put some quality mass on my hamstrings and glutes, leg size overall has been my main focus and they have certainly grown. I have absolutely no doubt I will be breaking pr after a few weeks back on the deadlift.
