Personal trainers need to have a multitude of skills. You should be analytical, patient, nurturing, persistent, organized, an effective motivator and, most importantly, a good listener. You should love working with different kinds of people and be a self-motivator. You don’t have to look like a body builder to be a fitness trainer, but you should definitely lead a healthy lifestyle to be a good role model for your clients. (from about.com)
If you replace fitness training with discipleship or spiritual development, it’s a pretty good match. We pastors do not need to be saints, but we should definitely have a healthy spiritual life to be a good role model for our churches.
