I am 42, and just got back into tennis after a 10+ yr break. I have been playing for about 7 months now about 2-3 times a week. If I mainly play from the baseline, my body recovers easily in 1 day. Most of the time, I play tennis twice a week on wed & sun only. I recently (1 month) started trying to get back to my serve and volley game. However, if I serve and volley, it takes 3-4 days to recover with all sorts of aches and pains :cry: When I serve and volley, I do so on both serves so it takes its toll and my body aches after playing. Most of the time, the aches are in the knees, heel of my right foot, and back. My serve power is mainly from knee bend. I do not arch my back now while serving, so I am guessing that the back ache is due to body rotation when comming out of the serve and going up to volley. I do cycling, weights, and yoga ~3 days a week specifically to get my body ready for serve and volley. Any 'Older' guys out here who serve and volley and have tips to stay free off aches and pains?
