Start by listing:
Independent variable and units,
Dependent variable and units,
Control variables and units.

Think about sample size, how you will make results reliable and how you will make results accurate.
What exercise you will make them do and how it will remain the same for all. There will also be other possible factors you may need to think about, eg height, weight, general fitness etc.

Is this a 6 mark question or a bigger project?
