6-Pack Challenge – Week 4: Not a Success Nor a Failure
Technically, the 6-pack ab challenge isn't over until two days from now. However, being the weekend, those are my off days from exercising. I doubt very little will change physically until that point. So I'm calling it. Challenge over! The number 1 question everyone is likely wondering is if I did indeed build 6-pack abs. The short answer, no I did not. However, there's been a substantial increase in muscle mass in my core area and I've developed a 4-pack.
