O'Leary glad to be back.
The Kilmarnock defender made the trip to Core Fitness, based in Hamilton Accies' New Douglas Park, for a session on a space age antigravity treadmill.
O'Leary ran in the latest stage in his rehab under the watchful eye of club physio Alex MacQueen and said: "The anti-gravity treadmill is quite strange to get used to but once you get going it's fine.
"Just to be back running is a big step. My knee reacted very well to the operation and I can only put that down to Alex's advice and help."
