I dont do weights that much. Since I play tennis I do a lot of conditioning, and pushups, and crunches, and jump roping. But from time to time, I might even go to the YMCA with my friend today since I dont have school. (yeah, shes a member and im not, i need to become one) Im going to probably ball for a bit with her and maybe lift some weights. Im not sure, should be a good time regardless. Last time I actually used weights was during gym class sophomore year (so probably the fall/winter of 2004, now im a junior). I maxed out the leg press machine, at 430, 10 times with ease. I benched like 180 7-10 times. Leg Extension I did like 200. Yeah, as you can tell, my legs are jacked and I'm pretty proud of it. Helps me in tennis too, but I need to work on upper body strength and endurance this offseason. Itll make me a better player.But usually I just stick to running. I run 3 miles every day before school, and have practice after school except on days in which we have matches. Its a lot but my body is used to it and I usually dont get sore any more unless I do lift weights.
