There's a guy at my gym, and he does a pretty heavy sldl of some
sort, but he concentrates on rounding his back. He starts with the
bar a little of the floor, the whole back, lower and upper, heavily
rounded, and slowly extends it to a straight position, then rounds
it back down, the bar again closing down on the floor, and then up
again. The legs remain very fixed in the same position.
There's always people doing weird stuff in the gym, and I would
normally just chalk it up to that, but over time I've become i
interested. This guy is a med-student and knows much more about
anatomy and related stuff than me, and seems to think a long the
lines of "progress gradually and joints, bones, etc. will become
stronger in time", which normally makes sense.
This guy started on the back-extension machine, progressing to
adding weights on his shoulders/back (common in my gym), up to 40kg,
and then to this sldl-variant, where he hauls 110+kg.
Now, I know that with even a light weight, attempting something
similar at this point will damage my back. I know this because I
remember at least one recent occasion where I, while warming up,
lost my concentration, and felt the "bad" kind of pain in my lower
back, as I let it round. This was with a weight of only 90kg.
What do others think of this exercise? I can see it targets some
muscles I don't otherwise train, except staticly, but most of what
I've read says you should not round your back when lifting heavy.
I've started experimenting with it a little, doing a few sets now
and then with just the bar, but would like to know more about it
before progressing. I don't want to hurt my back.
