I work out three days a week, two times per day (very early and very late in the day), just because I like it (I don't have a massive body, but literally working out makes me feel good so I go there as often as I can)
I do abs exercise (not many though) at the the end of each my work out session.
Though I generally like my body, the abs part is not exactly what I'd like to see, I'm still in shape I'd say, but yet I don't like that part.
I was thinking whether or not it would make sense adding one work out session where I focus only on abs, but still carrying on with my current routine for the other days, including abs.
The question is whether or not there a benefit in having a further workout day fully dedicated to abs (in addition and not substitution to the other days where I do abs at the end of the workout)?
