The Foxes will meet QPR on Saturday.
"It's been amazing," the Nigeria striker told LCFC TV, discussing the training camp. "We've been working really hard. You know, obviously, it's preseason, so we need to work hard and get minutes and prepare for this season. We've been working really hard and preparing ourselves, so it's going quite well.
"It's not been a bad week at all. It's hard and tough, but I think the last week was harder! It's been going pretty good and, of course, we need minutes and game time for everyone. Hopefully that's where we're heading and I think we're going in the right direction."
Iheanacho believes, although preseason friendlies are fundamentally about fitness, that Leicester's players are eager to give the Blue Army something to cheer this weekend at QPR.
"Obviously, it's to get minutes, but I think the results… of course, we want to get results in these games," he added. "It didn't turn out that way [at Wycombe], but hopefully in the remaining games, we'll get results and we'll be ready for the season.
