While Conor McGregor has been on a social media mission to prove he can beat Floyd Mayweather at his own sport, the boxing great hasn’t felt the need to flaunt his preparation.

Until now.

Mayweather posted a training video Thursday, his first since the much-hyped matchup became reality two weeks ago, and it shows McGregor might have a long way to go before the Aug. 26 showdown.

Mayweather captured himself on Instagram throwing a flurry of jabs at a bag suspended from the ceiling of his gym. The 40-year-old admitted he’s not the same fighter who went 49-0 over his 19-year career, with his last professional fight coming in 2015, but he didn’t express any doubt either.

“I’m just an old legend putting in work with 16 oz gloves,” Mayweather wrote, drawing attention to the one-pound boxing gloves he appeared to toss around with ease.

McGregor, as has become his style, went a step further in a video he posted to his own Instagram account later Thursday. The professionally done clip, titled “I Am Boxing” and labeled “Episode 1,” shows the UFC champion warming up in front of his favorite mural and sparring with a couple bigger bags at a much slower pace — all to the sound of dramatic background music.

“You’ve never seen these moves. #Ghost,” McGregor, 28, wrote in the post’s caption.

Considering this was the first episode of what should be a series leading up to the big fight, McGregor will have more chances to convince the world he won’t become just another of Mayweather’s victims — the momentous 50th one at that.

Until then, he’ll continue his quest to win their battle on social media.

“You are in quicksand,” McGregor commented on Mayweather’s video.
