Don't you find it frustrating that when you work endlessly on your abs, the lower part always takes the longest to tone? Course ya do. First of all, they are not easy muscles to connect to. The upper abs tend to take over the work when the core is in action. Weakness is also highlighted when the lower abs push out in an attempt to work. Plan of action?
