I agree with Brian, be careful, be good to yourself, and don't kill yourself just because you need the money. You could always study A-shiatsu (hang on bar from cieling, walk on their back) to work on her. I always wanted to try that, but I'm 185, 5'11" , and not oriental, so this would be kinda absurd.
bear with me here, I'm kinda playing here:
I find the most intense deep specific triggerpoint rhomboid pressure COULD be acheived by putting her supine and put a jack nobber under her rhomboid. You could have her lie supine on a heat pack first while you work her legs for 10 mins. Then do the above jack nobber thing.
Want more excruciating pressure? Fine. Therapist gently, gradually pushes shoulder into table/ jacknobber (Do not dislocate shoulder). Do ROM with her arms on the jacknobber. target supra/infraspinatus also.
I guarantee this will have her screaming in joyous agonizing pain, like a 12. I've done this with a couple super deep-cravers, and the've gone right to the edge, after 10 mins, "OK that's enough". Pant, sigh. OMG.
Finish with some nice fluffy effleurage.
This is surprisingly easy on your body to do, BTW. It's "active release" work, just with a tool. I do this on myself, my shouder is trashed from 15 years of archery, salt water flyfishing etc. I have yet to find an LMT who can produce anywhere near the specific pressure that doing the above creates.
Just make sure you have good insurance, and check what modalities your plan covers. This is really closer to PT work than MT, so beware.
Edit note: I just checked my insurance, and it says you can't use tools or implements. I don't use tools (ie massage stones) anymore anyway.
I don't think you would be held liable if you suggested say, a body rolling class or use of a tennis ball, jacknobber, etc. hot stone, etc. to them to use on their own in between sessions. If a client were to actually get motivated enough to learn how to release their own TP's, that would help your session greatly. I've tried suggesting this to quite a few people, but they never seem to bother to follow through.
It can be tough sometimes to try to "fix their wreckage" with a "9-11" session. Please keep in mind I am a male, and have strong arms and hands, but I have had 125 lb. women clients test my TP skills to the max. You are not alone. So don't sweat this.
Pls. note: I am not of the "No pain no gain" rolfing etc. school. I believe in being patient, sinking in slowly (like cornstarch etc.) But there have been some who have been beyond my skill level. Those have been reffered out. Again, It's not worth killing yourself over.
Weight lifters are a tough bunch. But definitely watch using fingers or hands on those rock hard areas, instant blow-out. If you can't ultimately deliver the bone-crushing depth she craves, remember it's her stuff, not yours. Just go get another client, and you'll quickly forget about all this.
There's only so much you can do. I don't think she'll be critical of you for just not being strong enough. That would not be fair IMO.
