Stuart McCall's side have played just once since the winter break – in a 3-2 win over St Johnstone last month – due to adverse weather conditions, and just twice this new year.
By the time their game against Dundee United was called off 10 days ago, the Fir park players were already lined up in the tunnel raring to go.
But despite many expecting them to be out of practice by the time they roll up at Rugby Park tomorrow, striker McHugh has warned Kenny Shiels' men to brace themselves as Well look to announce their return in style.
He said: "I don't think we'll be rusty – I think it will go the other way for us. We are desperate to play because it feels that we have been sitting around for the best part of a month.
"Training is all very well, but there is nothing like playing games. There is an edge to us just now because we are wanting to get back to playing and hopefully to keep up our fight to land second place."
McHugh's contract is up at the end of this season but the player is adamant that his situation won't distract from his focus of pushing his way into a regular start.
"I don't want to worry too much about it," he said. "I've got to use it as extra motivation to get my chance and then take it.
"The manager has always been very encouraging with me and I do feel that I am going in the right direction. The next step for me in my senior career is to try and establish myself.
"I have worked really hard over the last few months on my all-round game, including my fitness.
"I hope that in the second half of the campaign that I can start to see the benefits of that."
The Fir Park side are hunting down a second-placed finish after landing third last term, earning a Champions League qualifying spot in the process.
They are currently joint- second in the SPL with Inverness, three points in front of fourth-placed Hibs with two games in hand.
And with just 15 matches left for Motherwell until the end of the season, McHugh has his eye on the prize.
"It is all about getting results now," he said. "You always want to play well and win but when it gets to this stage then it is about keeping up your momentum.
"I'd really like to think that I can help. I want to try and get myself among the goals and hopefully help the club to keep up the chase.
"But Kilmarnock are a side that we have respect for and we know they'll make it hard."
