I never liked sumo dead lift, however I find them to be easier, being the weight doesn't travel as far as it would conventionally. I prefer the conventional over under hand grip.

I have degen disc disease(basically multiple deteriorated discs) also 3 bulging disc and have had many procedures( no internal surgery) I have some good days and bad days. I haven't attempted a deadlift in a year. I am able to do straight leg deads. I keep weights on the lower ends(like a 20 rep max) Also i like to do rack pulls. I can go heavy and can tolerate the slightly uncomfortable feeling unless my nerves are already pressing on sciatic nerve. Try em out you never know they might feel fine for you. Hit hyper extensions holding some weight. That will give you a wicked pump. Hope this helps ya bud. Remember on the straight leg to pull back your pelvis and hold it(called pelvic tilt) google it if your not sure. Learned about it in physical therapy i'm suppost to do it like everytime i do something except walk. lol

Im really big on wide stance... Romans and sumo deads are the bread and butter of my back routine, on my heavy day that is. I split my back routine. heavy day and definition day. and I know Romans are not wide stance! lol... I just like the sumos better... and if we were talking squats I would say spread em as well ! and Im not a tall dude by any means I just feel it activates my muscles more. But in all reality Sarge is right. Do what you can. If your in pain like actual pain not a good pain from lifting. Thats not a good sign any way you look at it.
