(Family Features) If you’ve recently begun a new workout regimen, you may find yourself wondering if you’re doing the right activities to really make a difference. Unfortunately, because everyone’s body, health and nutrition needs are very personal, there isn’t a one-size-fits-all answer to that question.

The good news is, there are some guidelines that can help you feel confident that you’re on the right track to better health. Pair these tips from the Centers for Disease Control with a discussion with your physician or a certified trainer, and you’ll be well on your way.

• Start by choosing activities you enjoy. While, yes, a workout is “work,” you’ll find more success in the long run if you’re getting those endorphins going with something that brings you pleasure.

• Combine moderate-intensity activity with muscle building workouts. This gets your heart rate up so you’re burning calories, while building fat-burning muscle and improving your overall core and strength.

• Mix it up. Avoid monotony and boredom by changing up your workout throughout the week. Get your cardio with a brisk walk one day, followed by a bike ride the next. Or if you’re working out indoors, vary the equipment, such as alternating among the elliptical, stair-stepper and treadmill.

• If you keep at a moderate pace (meaning you can still talk, but not sing), you’ll need about two and a half hours of workout time each week, plus at least two muscle-building sessions that work all your major muscle groups.
