I advocate plyometrics training and body weight resistance exercises.

Clap pushups, pull ups, box jumps, crunches, hanging leg raises, hindu squats, one legged squats, and hindu push-ups for strength training.

For anearobic conditioning plyometrics training, sprints in the sand

Aerobic conditioning - running, swimming - anything that gets your heart rate up and kept there for a while.

Another thing I'd suggest is footwork drills especially for twos in the sand. Small quick steps will help prevent injuries, along with make you more agile in the sand. Being where you need to be, and being able to shift as needed, is going to make your passing, setting, and hitting all better.
