Let me explain a hypothetical scenario to help me ask my question:
- Person A used to hold a good level of fitness, doing some hard sportives and sustaining periods of 200+ miles a week for around 5 years.
- Person B has never been this fit.
- Both people are currently lacking in fitness and both around 25kg overweight
Ignoring technique and prior knowledge, if and both people were to start the same regieme of exrcise and good diet at the same time, would there be any difference in their progress based on one having been very fit before?
