Cutting body fat will reveal your six pack, but it won’t make it look awesome. Your rectus abdominis is much like any other muscle – if you want to make it bigger, you need to work it harder. So if you can see your six pack, but it’s not much to look at, give this core workout a go. Hitting your abs from every angle and combining isometric (static) and isotonic (moving) exercises, this workout will not only add size to your six pack, it will increase your core strength as well.
