I'm 32 yrs old I just had a L4-L5 ALIF Fusion with a spacer and bone graph put in. I'm advised to wear a back brace for 3 months. I am a very active person who use to workout 7 days a week, but I'm advised to only walk for 3 months and that is the only form of exercises until PT starts in 3 months. Does anyone have suggestions from experience on what some light exercises I can do or what I can do?? I am going to go crazy not being able to do anything and my muscle turning to flab! But I certainly want to make sure I heal correctly so of course I'm not going to do anything crazy, just wanted to know suggestions of sitting exercises etc. of how you all may have gotten through recovery and the time line of eventually lifting weights again, thanks in advance!
