In order to work on your endurance and fatigue incorporating additional exercise is something that should be fitted in either before or after work, which is often difficult for many rugby players who have full time jobs. However recent scientific evidence from the University of Birmingham has shown that completing repeated high intensity exercise in short bursts (otherwise known as HIIT, High Intensity Interval Training) can be as effective as completing a traditional long endurance run or cycle, which is typically believed by many to be the only way to improve endurance and fatigue. With this form of training, performed several times a week, it has been shown to improve endurance capacity and reduce fatigue during exercise to the same extent as traditional endurance training. The added benefit of this sort of training, especially for those with full time jobs, is that it takes a fraction of the time compared to traditional endurance training. For example a typical HIIT session would include: 2 minute high intensity exercise at 80-90% Heart Rate Max with 3 minute rest period repeated 5 times. This equates to 10 minutes of exercise in total, rather than 45 minutes of traditional endurance exercise. In addition, this form of training can be done by running, cycling or rowing either in your house or at a local park and requires no additional equipment.
