It's been said, "You can't manage what you don't measure." That's certainly true with diet and exercise.
Unfortunately, most of us do not keep track of exercise details, like how often we work-out, what type of exercise we do and for how long.
It's also important to record how hard we're working, such as how much weight we're lifting or how fast our hearts are beating.
Too often we rely on our memory of such things, and as it turns out, our memories are pretty bad. Sometimes we tell ourselves we're doing better than we really are, or we don't recognize when we're ready to kick it up a notch.
"You don't see the progress that you are making, you don't know what you are doing," said Chelsea Ruffino, who remembers what it was like before she starting using technology to stay fit.
Now, however, we have no excuses, thanks to countless gadgets and gizmos that keep us on track.
These include bracelets that count your steps, monitor your sleep patterns and store all that information in an app.
Also, there are scales that can talk to your smart phone and tell it your weight and body mass index. You can buy headphones that track your distance and heart rate.
You can even wear a watch that tracks how many calories you burn while working-out, and an app to keep track of the calories you eat.
"It motivates you I would say more to know that you are actually doing something and you're making progress," Ruffino said.
No longer do you need to wonder why you're not seeing the results you want. By keeping track of what you're doing, you can identify the problem and make adjustments.
Dr. Michael Roizen is Cleveland Clinic's chief wellness officer. He says monitoring your progress, or failure, keeps you honest.
"This is a tremendous opportunity for us, if everyone uses a device, to get fitter," he said.
When you see with your own eyes how much better you are now than you used to be, there's no more effective motivation to keep up the good work.
