This week is not a good week for training. I don't know what's happening but I feel heavy, bloated, powerless, and desperate. Today it rained all day long so the trainer was at hand for me in the evening. I tried to do 3 times 5-minute intervals but I couldn't raise my HR enough with the first interval it was the highest, then on the second it dropped to 160-161 and the third one I could barely reach 160 This is only zone 4, I couldn't make it up to 5...And what is more, my HR dropped easily so I had to keep easy periods very short and my muscles hurt...
I'd better stop complaining and hope that next week I'll have better days
