How many hours a day do you practice when you seriously try to improve your skills? I started playing tennis for about 2 months and I am very impatient about my progress. I practice about 1 hour everyday but I found out that I can't do it any longer -- not from exhaustion but from my muscle pain in my thumb and a bit on the wrist. Maybe my muscle isn't accustomed to the usage yet? I hope i could put 2 hours a day practice in the future. What are you people doing when you try to rapidly develop ur skillz?
