These exercises should work all the major muscle groups. If you are a beginner, consult with a fitness professional for an orientation to familiarize you with safe ways to perform both cardio and strength-training exercises. Read labels before buying and eating protein bars. While they can be helpful between meals or if you miss a meal, there are different kinds of protein bars for different needs. For example, there are bars that are high in carbohydrates and calories for people who engage in endurance activities such as running and bars that are high in protein and low in sugar and calories for people trying to manage their weight or stay lean.
Some protein bars are nothing more than glorified candy bars.
To make sure that you are eating a protein bar, carefully read labels to find a bar that suits your needs.
