We went to play some tennis this morning.  Four of us started with the usual pairing and we hit the balls for awhile.  Connor enjoyed it the most when I stood next to him and dropped the balls for him to swing his racquet.  He had some good hits with this method.  After awhile, the kids wanted to take a snack and they had fun playing with each other on the sideline.  They finally returned to play with us but they were goofing around by then.  Rather than hitting from the far court, Stuart decided to toss the balls from half court to them to change things up.  The boys seemed to enjoy it as they had a better chance of hitting the balls.  Later I switched with Stuart and he became the ball boy to get more exercise.  I started rewarding the boys with more tosses if they were in a good position and had a good swing.  The boys enjoyed being challenged and were more motivated.  Their swings got better.  Logan made contact with almost all the tossed balls and the hits started to improve.  Connor improved on his contact and had some good hits too.  I was tossing to them as soon as they were ready again, so we were speeding up a bit.  They were so into it that they did not want us to stop until Stuart got tired of running around the court and my arm had become sore.  We must have been out on the court for over an hour and a half, and done a hundred tosses.  We will have to continue this trend.
