Then practice cross court forehands for 15 minutes and cross court backhands for 15 minutes. That's a total of 1 hour. From there, if you have the time, you can practice cross court volleys while one practices passing shots. But, however much time you devote to drills, you should always leave time to play a practice set at the end. That's more important than more drilling, IMO.
Best advice here, you also do need to practice overheads that's a hugely overlooked and pretty weak shot in recreation tennis imo.
