I went for a run on Wednesday and managed just under 2 miles before almost collapsing. This was a constant pace of 12km/h. After a few days of rest in between I visited the gym today and did 6.83 km or just over 4 miles. I did the 1st mile at 12km/h and then did each further lap either running at 12km/h or 6km/h. I found this much easier and intend to do it this way again on Monday. The machine also showed I had burnt 403 calories whereas on the 1st day I only burnt around 125 and I felt far more exhausted. I feel interval training is the way forward on the results so far.
I've cut down to one beer a night and intend to do the same 4 mile run every other day. Do you think this is a good routine??
Another question I must ask is why after exercise, even when I cool down do I feel lethargic for 2 days??
Thanks in advance
