Hasselbaink has now taken charge of three QPR matches – all of which have finished as draws.
Rangers have shown signs of promise in their first few fixtures under the Dutch boss, and Konchesky believes that the whole squad have been impressed by his ideas.
“It has maybe gone from not doing a lot to very intense, but that is not just for me that's for everybody,” the full-back said.
"We have adapted so far and we will adapt. It is going to be a tough Christmas period, so hopefully the training won't be so bad.
"The gaffer gets his stuff across on the training ground the lads have taken to it and I think you can see that from both games we have played so far.
"Jimmy has great ideas, he knows what he wants and if we can give him that he will be a successful manager.”
Hasselbaink’s first match in charge of QPR finished as a 0-0 draw against Burnley.
QPR then took on Brighton & Hove Albion and came back from two goals behind to claim a point, before they picked up a 1-1 draw against Bristol City at the weekend.
QPR had actually looked as if they were about to claim the three points at Ashton Gate, but they were denied their first win under Hasselbaink’s stewardship when Aaron Wilbraham netted late on.
QPR are currently in 12th place in the Championship table, five points away from the play off spots.
Hasselbaink’s side’s next fixture comes against Ipswich Town on Boxing Day.
