We can boil it down to incentives. Are the incentives (we recognize) strong enough to get us to pay for a membership and go to the gym? Maybe yes. Maybe no. Maybe maybe. The "maybe Maybe" wins the day in most cases. It's no surprise that the gyms are winning out here. Their goal is sales not necessarily our fitness. If they make good coin and facilitate people getting fit then good show. If they make good coin and the customers fail well such is life. Free will is after all free will.
So what can we say for the minority that pay the 30(+) silver pieces and actually make it happen? I say good show! To those who pay and drop off I say keep on; don't give up, go back and try again! Tomorrow is another day. Don't Judas yourself.
