Whether you want to run a marathon or just start exercising regularly, having a goal is an important tool.

For many of us, getting regular exercise is challenging enough. But it can be even tougher when you've taken off a month or more.

A training log helps you organize and save information about your exercise routine so you can work toward your important goals.

Interval training alternates short bursts of intense activity with periods of "active recovery," which means more moderate forms of that same activity.

If you don’t have the time or money to meet with a trainer, just hire yourself to get the job done.

Like your signature, the exercise routine you prefer is individual. If you’re outgoing, for example, working out in a group situation could be what keeps you coming back for more. A more reserved person, however, might do better exercising solo.
