The path to physical fitness requires self-discipline. 

Self-discipline is the ability to push yourself forward, stay motivated, and take action, regardless of how you're feeling, physically or emotionally. ... 

Motivation and willpower contribute to it, as do persistence, the ability to follow through on your intentions, and hard work.

All of these qualities contribute to success in business and in relationships. 

Do you think people who possess these qualities would be interested in your programs? 

Would they use them and become raving fans? Would they promote them to their customers if you asked? 

What if you had an app you could give them that held a free sample of your services?
