LAGuy1979 saidA few times a month when it occurs to me. I don't like ab exercises and abs are made in the kitchen. Not the gym.
I work abs along with my entire core...not for loks, but to prevent my L4 and L5 from herniating...again.
And 5x/wk definitely feels better than what I've been doing lately. As it stands, my right foot as been tingling some if I sit too long (which I have to for work). Gotta step it up a bit, but get tired of the same exercises all the time. I've got lots of core equipment back home to prevent burnout.
