I'm noticing a bit of an ache in in the lower back tonight... Was doing SLDLs as part of me high rep routine earlier and a dull ache has set in as the night goes on - never had DOMS of the back before... Form did slip on the last few reps but no obvious point of injury

Anyways - I was thinking of swapping out SLDLs for good mornings next leg day - Friday. Any opinions on this - I've checked it out and they seem to work the same group - hams and lower back, I'm hoping they'd put more emphasis on the hams. Obviously if I'm paralysed I won't be doing anything involving the back too much or on the flipside I'll be business as usual should the ache subside. So, Good Mornings - "No they're gay" or temporarily OK?

I have problem with bar placement with them, i find it rolls a little at the bottom of the exercise which i find uncomfortable.. might just be me being crap at them tho

Good morning are good,added them to my leg routine several weeks ago.As long as you keep strict form you shouldnt get any problems with lower back(i have a dodgy back already).

Cheers guys - will watch the rolling bar and form. Been viewing a couple of vids so I'll have a bash before I start and watch my form. gonna sling out BOR on upper tomorrow - do upright instead - give the lower back a rest.

They're a risky exercise dude - Bruce Lee's acting career was over when he injured himself doing good mornings. Why not give Romanian Deads a shot? The form's a lot easier to master than SLDLs and they're a lot less likely to recruit the lower back

Romanian deads - food for thought - researching...

Good mornings will help you improve your squats, RDL's will help you improve your deadlifts.

I personally don't like GM's but have been considering them for my new routine for the above reason. I think this exercise is better kept in the 8-12 rep range maybe? I certainly wouldn't like to do this exercise with a weight so heavy I could only manage 3-5 reps! James Copping certainly rates them though and I'd say he knows his shit better than me

RDL's, once mastered are a simply awesome exercise and you can really start moving some serious weight, much more than GM's and much safer too. Son of a bitch to learn though.

it probably has a llot to do wiht your proportions whether SLDL or GM's hit your hams the best.

im 6 foot with 32" legs....good mornings dont to jack for my hams although sldl work them a treat.

it would be interesting to see what peoples size etc is when stating what works best for them
