For summer, yes.
Don't mind them disappearing during a bulk.
Best I've ever had back at my highest level of fitness was being slim and lean with toned Arms, Lats, Traps, and Legs. I had a visible six pack abs set with obliques and the "V-cut" when i flexed, but i never was able to achieve true definition and bulking of the ab muscles themselves to have what your profile pic has for example....
I just could never bring myself to "eat right" even back then when 3 hrs of my day 5 days a week was either in the weight room, running around a track or on a treadmill, or doing body weight exercises. Love food and soda too much haha.
For me abs are not a "must have" anymore, they use to be, but I'm more realistic with myself now and just accept my bad habits for the time being. Maybe that'll change again...
My must have is high level strength / power, and being healthy. Would i love to have adonis-like abs, and that cosmetic physique that make the ladies instantly activate their slut modes for me... absolutely... but my lifestyle is too chaotic for me to be able to honestly dedicate the time necessary for that goal to be in my reach along with everything else i need / honestly want my time dedicated more to right now.
Its a cop out... i know... i was a fitness junkie "back when"... and if my "Prime Self" saw me right now he'd wanna slap me around... but its just not a top priority for now.... so for now... abs are not necessary... just wanna keep high level strength.
