It comes after Britain's schools were closed indefinitely as the Government battles to control the spread of Covid-19.
The lessons called "PE with Joe" are streamed live on Wicks' YouTube channel at 9am, Monday to Friday.
The Body Coach TV channel has 2.05million subscribers and his first episode had over a million views.
There's no need for any equipment with Wicks' lessons designed to be done in living rooms using only bodyweight.
Wicks' sessions continue to provide relief for parents who are indoors with children all day while they're off school.
Taking to Instagram, Joe Wicks said: "It's called PE with Joe. It's a workout specifically designed for kids because when the schools are closed there is no PE.
"Don't worry I've got you, I'm going to take this over and get your kids moving and feeling energised, positive, optimistic.
"I am going to be the nation's PE teacher starting from Monday! Don't forget your PE kit!".
Sharing a screenshot of some of the videos already on his channel, Joe added: "Exercise can transform the way you feel and react and interact with everyone around you."
He later shared another photo on Instagram promoting the free lessons and captioned it: "I produce so much free fitness content online and I never ask for anything in return but today I need your help.
"I need your support to help spread this online so as many parents as possible know that this is an option for them to use next week.
