, McGregor shared pictures of some of the club's young members watching in awe as he prepared to spar.
In the caption, the 34-year-old said: "Boxing for the kids," which was accompanied by more action shots of his sparring session.
The former two-weight champion has been out of action since his gruesome leg break last summer.
After many push-backs, McGregor is eyeing a return to the UFC early next year, but it remains unknown who his opponent will be, with Charles Oliviera and Michael Chandler mooted as potential foes.
One fight that has moved closer, albeit further down the line, is a trilogy fight with old rival Nate Diaz.
The American brought a storied run in the UFC to an end on Saturday night with a main-event submission win over Tony Ferguson.
Following his win over El Cucuy - the last fight on his current contract - Diaz vowed to expand on his horizons.
In doing so, he aimed a dig at former rival Conor McGregor, who has left MMA in the past try his hand at boxing, wherein he fought Floyd Mayeather.
Diaz said: "I want to get out of the UFC for a minute and show all these UFC fighters how to take over and own up another sport how you’re supposed to do it."
"Cause Conor McGregor didn’t know how to do it. None of these other fighters know how to do it."
McGregor did not miss a beat in responding two his former rival, tweeting that Diaz would be 'nothing without me'.
Speculation concerning whether or not there would be a third bout has circulated for years, without anything coming to fruition.
