Have you met with a pt?? If not request one through your hospital. If your doctor can't help, ask to speak with someone in social services. Your insurance should cover this. I had a pt come to the house after this surgery and he gave me exercises to do. I can not advise you about strenuous activities as I have never liked any. My theory is that one only needs to be in as good a condition as necessary for daily life and if necessary to do more the adrenalin will kick in and you'll just have have sore muscles. There have been posters here who have gone on to biking, skiing, etc. I was told not to put weight bearing activity on my leg for about a year. However as you are young and in good condition your case may be different. Scuba diving seems safer than skiing although there may be a problem with pressure. Ask your surgeon. He has experience and knows the risks.

Realize that surgery is just like any injury. Muscles and other tissues need time to heal properly. You want to help the healing process and not cause damage which could be prevented.

Good luck
