If you want nice abs, do cable crunches. Anyone that has done a set of 20+ cable crunches with proper technique knows how much these hammer your abs.
Also remember to do your squats, your bench press, and your over head press. These are all great muscle builders! Proven to work, time and time again. Big strong guys have big strong bench, ohp, and squat.
Leg raises target your abs too. Don't forget to do your leg raises! EXCELLENT ab builder.
That's all anons. WAGMI.
