When you get older as a double's tennis player, position on the court really matters. The usual one up one back scenario sometimes become detrimental. Why? The Lob becomes much harder to cover and the lane, the path halfway between the two players, becomes more difficult to protect. Many of my older students threaten to quit playing because they cannot cover their own lobs. Also, many of my older students threaten to quit because their partner cannot cover any of the lobs. What to do?
 
Try starting in different positions. Try both back. Definitely to diminish the lobbing. Also, when one of you hits a shot and goes to the net, try to come in together. If the ball you hit goes to the deep player, stop on the service line so you don't get lobbed. If the ball goes to the short player, near the net, then you should both go in and finish the point on the short players' half of the court. That way, no more lobbing.
 
Remember, the best way to play is both up. The second-best way is both back. The worst way is to be in the one up and one back position too long.
 
You can start back with your serving partner. You can start back when your partner is receiving. This will always help with the lobs. When you are forced to come to the net you must come in together. The more balls you hit to the opposing deep player, the more you will get lobbed. The more balls you hit to and under the short opposing player, the less you will get lobbed.
 
Good luck on the courts!
