Dennis Quaid Feel the Burn Of My 8 Pack

0105-dennis-quaid-ripped-hawaii-AKMGSI-01Dennis Quaid relaxed with an 8 pack on his Hawaiian vacation, but no beer was involved ... that we could see.

Quaid showed off his hardcore abs along with his lobster-red tan poolside on Oahu's North Shore. Normally this type of thing wouldn't be a big deal ... except Quaid is flippin' 61!

Can't knock his gym hustle. However, he should know to apply sunscreen more liberally.
