Yes and no.
No; for core strength to assist in lifts, not necessarily essential if your core is not a weak link in the lifting chain.
if your ripped but skinny training abs heavily will make them pop more.
Yes; if your not already ripped doing ab work is nigh on useless you get abs by diet and cardio not by banging on abs. At the end of my last cut with visible abs, i did no ab work at all and i feel training them would not have made the results any better
