Hey I am going off to college. I have played tennis for 12 years, and the past 5 years have been playing in the advanced level. I currently weigh 136 and was working on getting to a lean 170-175. I am 6 foot. Is that a good weight for college tennis? I like being 136 since it lets me move very quickly from baseline to net, vice versa and return balls hit on the opposite side. Only problem is I lack power that people outweighing me have. All advice is appreciated.
