'Cheer' Star Jerry Harris' Life In Federal Prison Has No Room For Cheerleading

Jerry Harris, star of Netflix's "Cheer," is getting a new routine ... and TMZ has a glimpse into his life in federal lockdown.

Jerry is about a month into his 12-year prison sentence in his child pornography case. He was recently transferred to a federal prison in Oklahoma City, where his daily life will be a huge culture shock.

Jerry's going to need to find a new way to stay active, because the only fitness opportunities are basketball, handball, walking and lifting weights.

Other ways to pass the time include hobby craft programs, board and card games, group discussion, letter writing and TV viewing ... but the inmates don't get to pick what's on the tube.

Jerry's got a new bedtime too ... lights go out at 11:30 PM on weekdays and 1 AM on weekends ... but there's no sleeping in ... he's gotta be dressed and out of his cell by 6 AM.

It's unlikely Jerry will make many friends on the inside ... guys who plead guilty to child porn aren't exactly welcomed by other inmates ... but he can see visitors on weekends and federal holidays.

Jerry's also hanging up the cheer uniform for standard prison garb, which he's got to wear from 6 AM to 4 PM during the week.

Outside those hours, he can wear clothes purchased through approved channels. Oh and he's getting a new barber too, one of his fellow inmates.
