Multi-stage fitness test (MSFT)
1. Run shuttles between two lines 20 metres apart, starting on the first bleep
2. Your foot must be on or over the next line when the next bleep sounds
3. The time between bleeps gets shorter as you go through the difficulty levels
4. If you miss 3 bleeps in a row, the last number of shuttles completed are noted as your final score
5. The higher the level and number of shuttles completed, the better your cardiovascular endurance
