How do i get tighter abs?
I hit my gym 3 times a week each time for 1 and a half hour, should i add swimming? would 2 times be good? i have a normal body, i'm not fat or small. I eat good stuff and drink fast carbs pre- and protein powder post workout. i want my abs smaller and more tight, so sit ups is useless for that, right? should i do plank exercises?
