Query: If you can get it to start, it is pretty good.

It works pretty good, but it is hard to start it. The system is too complicated, and I am a 40 yo male who works out 4-5 times a week. But I have difficulty getting it started. Most time, it causes a blister pulling the chain before it would start. That is the main concern.
