What Are the Eight Muscle Groups?

Physical activity has to be something that you really look forward to doing. You can start with leg exercises because they are the biggest muscles in your body. For abs, you can start off with a plank, and then if you want to make it harder, you can do crunches or leg raizes. Making it even harder,you can do a declined situp. And you can add weights to that according to whatever level you're at.
