In order to improve your fitness, you will need to manipulate one of the following three training variables:-
·The duration of your work out (how long each session is).
·The frequency that you work out (the number of sessions per week).
·The intensity of your work out (how hard you train).
first two variables (duration and frequency) quite obviously refer to training longer and more often as a means of improving fitness, or performance. The third variable, intensity, refers to how hard you work out and how much effort you put in, and there are numerous ways of adding intensity to your training. Our aim here is to provide a no-nonsence guide on exactly how to do that. Let’s face it, many of our lives are busy and hectic enough without having to try to find even more time to exercise. So here is some practical advice on how to get more out of your existing work out time.
