I have been having a discussion with a colleague about training. he runs twice a day, once in the morning, once in the evening, for about 20 minutes each time.
Now, I think this is not as beneficial as having one long run of 40 minutes per day, unless of course it is all performed at very high intensity.
He's also asked me whether he would get similar benefit from running for 20 minutes then weights for 20 minutes.
What's the received wisdom on this?
