Flexibility- For flexibility you can do the sit and reach test. The advantages of this are it is relatively cheap, not much equipment is needed apart from a box with measurements on and a magnet to move on it. A disadvantage for the traditional sit and reach procedure is that people with long arms and/or short legs would get a better result, while those with short arms and/or long legs are at a disadvantage. The modified sit and reach test controls for this, as the zero mark is adjusted for each individual, based on their sitting reach level. This test only measures the flexibility of the lower back and hamstrings, and is a valid measure of this.
Strength- A way to measure strength you could do 1 repetition maximum. The maximum weight lifted is recorded. The sequence of lifts should also be recorded as these can be used in subsequent tests to help in determining the lifts to attempt. The only equipment you’d need is Free weights (barbells, dumbbells) or other gym equipment. An advantage for this is that the equipment is already readily available in gyms. A disadvantage is that performing a maximum weight lift is only for advanced weight trainers and it is important to have good technique before attempting this test.
Aerobic Endurance- To measure aerobic endurance you can do the bleep test. This test involves running between two lines 20m apart in time to recorded beeps.. The subjects stand behind one of the lines facing the second line, and begin running when instructed by the recording. The speed at the start is slow. The subject continues running between the two lines, turning when signalled by the recorded beeps. After a certain period of time (a minute), a sound indicates an increase in speed, and the beeps will be closer together. This continues each minute. If the line is reached before the beep sounds, the subject must wait until the beep sounds before continuing. If
