Training in sports teams is best for all-round fitness. Team sport players have endurance and stamina. Researchers say the key to all-round fitness was strength, endurance and stamina. Cycling, running or swimming is great for this. Doing housework and climbing stairs was also good.

The study looked at 228 athletes. There were cyclists, bodybuilders, and basketball and football players. The researchers tested the athletes' power, their ability to jump, and their oxygen use. A professor said power athletes should do endurance training and endurance athletes should do power training. Team players do both.
