I bought a bike last June. Just after a couple of times riding I had some quite serious relapses followed. I realized that biking (for me) requires more heart strength. Since my heart is my major problem so I quit bike for long time. However, after feeling more energetically recently, I decided it's time to try biking again. Last Saturday, after one of parents of my students pumped air into tires of my bike (I had some difficult to do that and he was so kind to help me), I started riding bike again. Since then, I biked about 5 times, averagely once per day, and each time about 25 to 35 minutes, and I found myself not only "survived", but also feeling better. It helps my metabolism tremendously.
I don't remember it's been how long I have not enjoyed biking. The last time I really biked was over 10 years ago! Still I cannot ride bike all the way from beginning to end, because I had to stop to walk whenever go uphill (the neighborhood is not perfectly flat), even those "hills" that are not steep at all. Today, when I walked along street a lady stopped car and asked if I was alright. I thought that was very kind of her.
Anyway, after being tired of recording the progress or declines of my chronic condition, this, truly is a major improvement that is worth for me to write down!
