I don't really understand this. I'm now 4 weeks into the program and my energy levels during the runs are fine (obviously tired at the end, but I can get through them ok).
However, everyone says that exercising gives yoyu energy, you sleep better etc - well, I'm finding the opposite is true.
I'm tired all the time, especially in the days of my runs (I run first thing in the morning) - literally I have no energy, and come around 8pm I can hardly keep my eyes open.
Is this normal? Is it just my body getting used to the new regime? If so, any idea how long the acclimitisation period lasts for?
Foir the record, I'm 36, and over 18 stone, so I'm not exactly used to this exercise.
