I'm working on a tshirt and want to use the phrase
"Doing it healthy and safe."
Or should it be
"Doing it healthy and safely."

Those dang -y endings. Hard to make it snappy and rhyme, since when one word gets the -y, the other loses it! So "health and safety" becomes "healthy and safe"... hrm.
"Doing it healthily and safely" would be the correct, formal-writing form. But it is a bit wordy and not very snappy.
"Doing it healthy and safe" will raise some eyebrows from grammar prescriptionists, but is acceptable in speech in many dialects: it's probably fine to use in casual speech, or on a t-shirt, just not in formal writing. Some people will probably dislike the slogan for being "wrong", but hey, it's a conversation starter at least!
"Doing it healthy and safely" mixes the forms of the words, and feels very awkward because of that, despite the fact that both get the -y ending, which sounds nicer.
You could consider alternatives like "Doing it in health and safety!", maybe?
