To make a long story short, a very wise, fit man in what is probably his 50's or 60's had a hitting session with me and my hitting partner. It took us a while to take him at his word, partially due to his heavy eastern european accent coming to the both of us from the other end of the court, but he was telling us to go FULL out on the ball. He basically told us to forget that the baselines existed, and stand about 6-8 feet behind the baseline (he did the same on his end, and there was one of him and two of us). He wanted us to hit the ball so that it would only have to bounce once before landing in the receivers hitting zone. This often meant landing the ball beyond the baseline. He said that this exercise is excellent for just letting loose. After 10 min or so of this, he said to go back to normal rallying dimensions. From what I understand, the wisdom of this exercise is the following: In order to hit that far, it's harder to get away with arming the ball. You are forced to utilize your entire body's kinetic chain in as efficient a manner as possible, so you are essentially forced to discover good technique! Amazing stuff, and I wonder if this is a well known exercise. Another thing: this guy was more than holding his own against us. He was running down the ball even if it landed wide (like well beyond the outside doubles alley!). Incredible speed and power on this man. I made a stunning observation halfway through this drill. Every time we went to collect the balls (we were using about 6 of them), they were on our side of the net - about 95% of them!
