Yesterday was the 6th day in a row to ride bike in the morning. Recently, I was feeling easy to be tired and having gas in my stomach, hard to focus long enough when studying, etc. So, I was asking to my self that even though I'm just studying 4 subjects in a week that's 12 hours and doing nothing, why I can't exercise daily and feel bad. I was hard to breed and felt some pain in my heart in first 2 days of riding, but I was OK after that. From 4th or 5th day, gas in my stomach disappear and I became easy to get up at the same time in the morning and very easy to get sleep and more. Exercising everyday means hugh to 40s. I was doing regular exercise on and off in the past. Whenever I was exercising I could feel I'm getting better. But, it is so dramatic in this time.Love to riding. :)
