FitQuest measures every step and counts how many steps you made over the 30 second test. If you step high, then you cannot go as fast as if you just lift your foot off the platform.
Technique plays a big role, so it might be a good idea to practice at home before you take a test. Rarely, some people seem to lose their rhythm during the step test and this really does reduce their score, so practice is important in order to get a fair result of your speed ability.
To improve speed ability you have to increase your lower body muscle strength and at the same time practice speed running. One way to do this is to sprint as fast as you can for 20 seconds and recover for 10 seconds, completing seven or eight rounds.
Another method is to try doing the ladder exercise. This is where a ladder is marked out on the ground and you have to step between each rung as fast as possible.
Fatigue depends on so many factors. For example, the heavier you are the more work you have to do for any given exercise and therefore you are likely to fatigue quicker. Your cardio respiratory fitness also has an important effect on endurance capabilities, as well as your muscle strength. To improve your endurance (i.e. reduce fatigue level), you need to improve all of these factors. This usually requires that you undertake some sort of endurance training.
Ask your personal trainer for advice and guidance which exercises are most suitable for you and, as always, don’t be afraid to tell them what exercises you don’t like doing. They will definitely want you to enjoy your experience.
