Was fused at l5s1 3 years ago. I am cleared to do anything I want- whatever I can tolerate. Low back pain from the hardware and surgery will always be present to some degree is what I was told. I have been doing core work- Glute bridge 1set 20 Single leg glute March- 3 sets 5 per leg Dead bug- 4-5 sets of 8-10. Bird dog- 3 sets 5 with 5 second pause with leg extended. Side lying leg abduction- 2 sets 20 per side 3 days per week for all of the above. I also walk about 3 hours weekly- usually 30 minutes per walk Any suggestions or experience like my situation? Thank you!
