Barbell benching, dumbbell curling, lean, mean, lifting machine, John is ready to hit some iron!

do i need a semi colon anywhere?

IMO it's an extremely awkwardly constructed sentence, but

"Barbell-benching, dumbbell-curling, lean, mean, lifting machine John is ready to hit some iron!"

would be the proper way to punctuate it.

Compound adjectives made by joining a noun and verb in gerund form should be hyphenated unless they're already well-established in the lexicon as a single word.

"Barbell-benching, dumbbell-curling, lean, mean, lifting machine. John is ready to hit some iron!"

no that's wrong since the adjectives are describing John

they're describing the lifting machine (who is john)

can we reword?

John is a barbell-benching, dumbell-curling, lean, mean, lifting machine and is ready to hit some iron.

then there shouldn't be a comma after 'mean'

Also, the sentence fragment should be avoided considering OP is probably writing this for a formal or academic context.

At any rate, rewording it is preferable to either.
