Hi...
If I were you then I would definitely like to stabilise my spine with core stability and glute stability exercises..progressive increase the load and work for strength as well. .
You need lot of strength and stability as the changes noted in your
MRI is attributed to constant loading in those places....
Until you get good support and stability for your spine..which you will be getting when you start to work on core and glute stability... I recommend you to avoid any forward bending activities...lifting weights as these might irritate the structures and cause discomfort and pain...
Initially for core you can start with Dead bugs...Hundred...Side plank...spine extension...Superman reach...
Fir glute stability... clamshell...Bridging....Side keg lifts..Step ups...etc...
Don't hold your breath while you do these exercises...whenever you happen to lift or squeeze breath out..
Thesr exercises can ve done initially fir two weeks and then progress....Rehab to be done atleast for six weeks followed by a good
weight training program...
Hope this is helpful for you
Revert back in case you need any further clarification....
