tpeter,
That's why I used both scenarios in sweating and/or breathing. It's one or the other or both. Light weights which are for "toning not building" muscle tissue usually do not get one breathing heavy. You know your body. You know your routines. You'll know when your heart rate raises to the point where your breathing has to catch up. No exertion.
IMO, the scar can take "up to" one year to completely heal and I'm including the inner dermis. People have variances in how they heal and how quickly they heal. Not that I'm speaking for any doctor nor practicing medicine, but I believe the general consensous of hair transplant docs will tell you to layoff that type of activity for at least 2-3 months. Why don't you e-mail some of the more known ones and ask them to respond and compare notes.
Anyways, it's also very good to take a break from weight lifting and rest that tissue for several months anyways. Watch how much muscle tissue you gain when you hit em' again when you go back to it. Getting a hair transplant is always a good opportunity to do just that and also to protect your big $$$ investment.
Try to be patient tpeter. The healing period in your scalp is important and why risk anything that is under your control? I mean listen brother, sometimes I get e-mails and calls from patients where things "out of their control" happen to them. You don't want to do something to yourself that you will regret later. Try to find another activity to fill that void that you might be feeling from not hitting the gym man. In no time you'll be in the clear! :wink:
