"Werk. You delicious babe!" said Oscar-winner Octavia Spencer.
"If I could like this pic numerous times I would," wrote fellow Aussie actress Ruby Rose.
Wilson's close friend and frequent workout buddy Hugh Sheridan wrote: "You look so HOT!" while Olympian Rennae Stubbs chimed in: "Look at this supermodel."
"Sweet baby Jesus! You look amazing," wrote the man responsible for designing Wilson's workout program, personal trainer Jono Castano Acero.
Wilson has kept fans in the loop with her gruelling exercise routine videos and motivational activewear snaps after making a very public New Year's resolution at the start of the year to ditch her unhealthy eating habits and kickstart a new fitness journey.
She wrote on Instagram: "OK so for me 2020 is going to be called 'The Year of Health'.
"So I put on the athleisure and went out for a walk, deliberately hydrating on the couch right now and trying to avoid the sugar and junk food, which is going to be hard after the holidays I've just had but I'm going to do it!
"Who's with me in making some positive changes this year?"
In an interview with E! earlier this year, personal trainer Castano Acero explained he had created a specific program for Wilson covering six days of the week.
He said he encourages his clients to work out daily for 45-minute sessions, noting "results come through consistency".
