All of these exercises - particularly together - are great for building well rounded, comprehensive core strength. The abdominal panel, obliques and lower back are all engaged in this 10 minute abs workout and while it's beneficial for a wide range of fitness levels, it's also beginner friendly.
Add this quick core workout as a burnout round onto the end of other routines or use this with your stretching routines in order to build a strong foundation for more intense training types. Remember, the abs are just like any other muscle in the body; they need rest - don't work your core muscles every day. If you do this workout on it's own, be sure to add a quick warm up before you start, and cool down once you've finished.
