I have been recently diagnosed with OP and so far this is what I have done:
Initial 2 weeks - no training except some medium bench sessions / very light technique work.
Currently attempting to KB Swing my way through it as mentioned by Grah.
One of the threads on AUSBB I found had this as the suggested rehab plan:
Ukranian Deadlift - 20 x 40kg. 1 set.
Bent Knee Good Morning - 10 x 20kg. 3 set
Stiff legged deadlift - 10 x 40Kb. 3 set.
hip abduction using elastic bands - 15 reps 3 sets
Leg raises (lying down, bring knees upto chest and back).
Squats BW 15reps 3 sets.
For squats, I have found I can box squat (parallel or above) without aggravating hips/adductors, so that's what I have been doing.
Deadlifts (Conventional, Stiff-Legged, Romanian) seem to be fine and actually help, I just can't seem to generate as much power as pre-injury.
Also keep doing your physio provided exercises (clam shells, leg adduction/abduction, glute bridges etc) every day!
