A high level of general endurance is the basis of all training and should be part of any training programme throughout the whole year. The recommended methods are cross-country running, cycling, swimming, canoeing and rowing . Each period of exercise should last more than 40 minutes.

Circuit training is another good method. It should contain between eight and fifteen different stations. There may be a number of different exercises possible at any one station, but avoid having the same muscle groups worked on the adjacent stations. No rest should be taken between any stations, but rest is appropriate between circuits.
