It’s all good man, you don’t have to follow CC to the letter. I actually don’t care for a lot of the progressions within that particular book, and would instead point you to the progressions found in Al’s books. Also, yeah feel free to add a 3rd day. While what Coach Wade says about progressing slowly to maximize gains is valid, it’s not the only way. You can continue doing the easier stuff but you can also skip ahead to harder stuff, more workouts, etc, as long as you take care to not injure yourself. Push the limits, just don’t break them. If you feel like you’re ready, then you probably are.
