Appearing on Strictly spin-off show It Takes Two, the Steph’s Packed Lunch star explained that the strenuous dance rehearsals have been taking their toll on him.
Speaking to host Rylan Clark-Neal about being a finalist, John said: “My body’s falling apart, my emotions are all over the place, but I am so happy.
“It’s just been, I’ve said it before, a fast train journey through beautiful scenery and it goes so quick you can’t take it in.
“Whereas, this week it feels like we’re just at the top of the mountain now looking around and we’re having a great laugh,” he added.
The Strictly Come Dancing final airs tonight at 7.10pm on BBC One.
