Set Measurable Goals
If you're serious about becoming more fit, be sure to establish goals that are measurable. Too many people do themselves a disservice by setting goals that are too broad or vague, and wind up feeling frustrated (and, in many cases, quitting their program). In other words, one of the best ways to make sure you succeed is to determine beforehand precisely what success will look like.
