Hello and thank you for your excellent question. You should be safe for spin class 6 weeks after a BBL. Of course, you will need an in-person consultation to evaluate you for this procedure. Preoperative visualization and surgical simulation with the Crisalix system may help with your decision. Any treatment plan should be based on a detailed discussion with equal input from both you and your surgeon. Make sure you specifically look at before and after pictures of real patients who have had this surgery performed by your surgeon and evaluate their results. The most important aspect is to find a surgeon you are comfortable with. I recommend that you seek consultation in person with a qualified board-certified plastic surgeon. Good luck!
