In general you should be able to get back to normal activities in 6 weeks.  Always check with your plastic surgeon for his recommendations prior to starting an aggressive exercise routine.

Most surgeons allow return to normal activities by 6 weeks, but for something like this, many would want a longer delay (?three months).

All the best.
