1. You're not working hard enough.
If you have been exercising consistently for several weeks, months or years, it's definitely time to increase the intensity and start pushing yourself. As you work out more and more, your body adapts and becomes more efficient at doing that certain activity. This means that over time, the 30-minute workout that was challenging for you three months ago doesn't provide the same results. In fact, you're actually burning fewer calories and your body is no longer changing if you're still doing the same old thing.

Get-Results Remedy: In order to get results from exercise, you have to regularly push yourself beyond your fitness comfort zone. Whether you increase the frequency, intensity, or duration of your workouts, you have to switch it up. Not sure where to start? Try adding an extra day of cardio onto your routine, testing out a new group exercise class at the gym, adding another loop around your walking track, or bumping up the incline and speed on the treadmill. Remember, when it comes to exercise, change is good—and that change should be challenging!
