Can I do bodyweight squats/isolated leg machines 2 weeks post op BA?

These questions are best answered by your surgeon as he/she is most familiar with the details of your surgery and how you've been progressing through recovery.  When returning to exercise it is recommended that you begin slowly and then progress.  Lifting weights above 10 pounds, or any activity involving bouncing or jumping should be avoided for approximately 6 weeks.  Your surgeon will advise you on what is best for you.

The answer is to ask your surgeon to get the best advise. For my patients, I will let them do lower body exercises in two weeks.I restrict upper body exercises for the first four weeks. Good luck!

You are probably best served by checking with your surgeon. We plastic surgeons all have different ways of doing things including the resumption of exercises.
