I am a 17 year old girl (50kg, 158cm) and i need to get a good school mark...
To be clear: In 3-4 weeks we make in class a cooper test!
A cooper test means= run 12 min and if you reach a certain distance you get a good mark... I need 3km !
The only problem... I don't know how to train my endurance!!!(I don't make much sport at the moment, but I played soccer 2 years ago ) Can you guys give me the know-how how to train running?
