​I advise no exercise for 6 hours before injection neuromodulator (Botox) therapy and 12 hours following the injection. Why? I want to minimize the risk of bleeding and bruising as well as the chance of exercise-induced increased facial blood flow decreasing the amount of time that the injected product has to work on target tissue (facial muscles).  This maximizes patient results both short and long term, which is well worth the trade off from missing a single work out session.
