This workout is exactly what I needed to kick off a new month. I did this workout yesterday and believe me when I say your abs will be totally worked with this workout, obliques and all! There are several different exercises to target the entire abdominals, and also a few planks are thrown in there for fun. Don’t be discouraged if you can’t hold the plank – especially as it gets near the end of the workout. If you can’t hold it, drop your knees to the floor, take a quick break and raise back up. Aim to keep any rests minimal.
