I just finished

All my spinach

Been a tussle

Growing muscle

Wannabe a tough guy

Biceps like Popeye

Despite the toil

Limbs like Olive Oyl

Its a mortal sin

Arms stayed so thin

Belly is fat

Instead of flat

Mr Universe dream

Ran out of steam

Fat ass now on couch

500 reps of slouch 

Diet stuck in first gear

Open another beer

pass the remote

Snacks down throat

Wearing loose clothes

Over my speedos
