The Warriors tighthead prop required minor back surgery during the close season, but has been back lifting weights and doing fitness work for three weeks and is eyeing a New Year return to the fray.
With Mike Cusack establishing himself as first pick tighthead during Kalman's absence and that of Moray Low, who was out with a knee injury, the big front row admits he has work to do to reclaim his place.
Kalman said: "Things are progressing well and I have been doing weights and general fitness stuff with running for a couple of weeks now. But you can't rush back injuries and the care I have has been fantastic.
It has been frustrating to sit on the sidelines while the boys have gone about compiling a new record of wins in the PRO12.
"But maybe even more so when you are helpless to make a difference when things don't go so well as was the case at Munster at the weekend.
"But the main thing for me is that I am absolutely on target for a mid- January return and the key at this stage is not to over-do anything."
With Glasgow left reeling by the 31-3 loss to Munster that is their heaviest defeat under Gregor Townsend, Kalman has backed his mates to bounce back by beating Castres in the must-win Heineken Cup clash at Scotstoun on Friday night.
He said: "The boys are hurting and there is a real determination in front of our fans to get the win we need. A response is required and I am sure we will provide one."
