some people start treadmill n bike at around 2-3wks and slowly work their way bk up. i personally waited 6wks until i had the all clear to start bk as i dnt think its worth risking doing any damage, as its also having sweat near your incisions and to do with your heart rate being too high, too soon after having the op,so its nt just about causing damage to the implants by physically moving too much.
at 6wks i stil didnt feel rite doin the rower or most arm exercises with weights,it took bout 8/9wks to feel like i cud start them again. i had overs aswel, unders take longer to heal too. i had a pretty long recovery tho. everyones different, u jst have to go off how u feel. u wil know if ur doing too much cz your body will tell u to take it easy xx
