The Hoops are looking to extend their unbeaten league run to 23 matches when they travel to St Mirren Park.
Although Lennon thought Celtic appeared jaded in Wednesday's 1-0 victory over Partick, he expects the extra day of rest to benefit the visitors as St Mirren did not play until Thursday.
"There was definitely a tiredness creeping into the team in the second half against Partick," said Lennon.
"I just want us to play with a little more zest.
"We have had a heavy schedule of games recently but we have had an extra day (over St Mirren) to recover from the Thistle game.
"So hopefully we will see a wee bit more energy in the team. That is what I am looking for."
