Im no expert and you should listen to you physical therapist, but here’s some ideas.
Do pressing motions that don’t hurt. it that means partials (upper or lower) do them but dont force it. A good therapy for elbows is slow tricep pushdowns with cable or a band with hi-reps and slow ecentric phase, really concentrate on the negative phase, some 12-25 reps. and then move to 6-12 reps when you feel ready.
Remember that biceps play a role here too, so hammer curls and neutral grip extentions would be ok, if no pain occures. pulling movements might aggravate the elbows too so listen to what you feel in you elbows while deadlifting, doing pull-ups or rowing. neutral grip in these will make a difference in elbow joint stress. and always do a thorough warm-up and give extra attention to the elbow joint.(bi’s & tri’s)
one thing you could do is to concentrate on squating movements and on heavy assistance work for the posterior chan, glutes and hams. And concentrate on speed while deadlifting.
when the PT gives a green light you could do a three week peaking on bench like week1 go to near max, week2 do some easy singles on 90% of that wk1 single and some RE on 70-80%, week3 try to do a bit better single but still just growing the hunger and after the single do some RE work. take the wk4 easy and do singles with 70-80% & relax. Know that you will destroy the bench in the meet.
hope that helps, but as I said, Im no expert.
