help me! (good mornings)

[rippedtrojan]

i did good mornings for the first time today ever! (as prescribed in tmag's gvt hamstring workout.) well, i was surpised to find out i could barely get out ten reps with 135.

my main question deals with form. i felt that i was strongest if used a knee bend (same type of bend when doing romanian deads) rather than going straight legged. as i grew tired through a set, i would start to introduce more bend into my knees.

also, i know there are flat, arched, and rounded back variations. for mass gaining purposes which of these should i be using?

should i keep my head up as i lower the bar, or should i keep it in a neutral position?

i think that is all i wanted to ask, but if i have any more questions, i'll be sure to let you guys know.

thanks!

i've never tried straight-legged. i especially wouldnt even try straight-legged bent over

I aim to keep my head up, and arch my back so that I'm trying to stick my shoulders and ass out at the same time, and allow a slight bend in my knees. That's way way it was taught to me by a powerlifter who could do triples with 5 plates per side. I wouldn't do sets of ten though, it's too easy to comprimise form with high reps, and this is about the worst exercise for that, if your form goes you're going to get injured. Since it's basically an exercise to build strength, I never go above 3-5 reps
