"Therapy day 3 post calf muscle tear, progress check…" the 37-year-old captioned the clip, alongside the hashtags, #MyDocIsBetterThanYours and #ModernDayMiracles.
In the video, Chmerkovskiy -- who is paired up with Glee's Heather Morris this season -- can be seen pacing back and forth, even demonstrating his sharp grapevine abilities. "It's getting there. Almost," he says.
On Thursday, a source told ET that Chmerkovskiy tore his calf muscle "pretty badly," and that he's undergone a series of shots to help recover. "It's a lot worse than everyone initially thought," the source said. "Doctors are insisting that Maks sit out for at least a month, but knowing Maks, he will try and rush it and get back into the competition."
In the meantime, Alan Bersten has been filling in during Chmerkovskiy's absence and scored 30 out of 40 with Morris during last week's episode of Dancing With the Stars for their jive set to "Grown" by Little Mix.
And Chmerkovskiy is confident the pair still has a chance this season.
"I still feel like we have a chance and you deserve it," he told Morris on Friday's Good Morning America. "I want to give you 150% effort and be physically as active as I was at my best when nothing hurt."
