Mr Motivator and Angela Rippon have signed up for a BBC One show to lift people's spirits during the coronavirus pandemic.
HealthCheck UK Live, with Watchdog's Michelle Ackerley and CBBC star Dr Xand van Tulleken will air every weekday for two weeks.
TV veteran Rippon, 75, will be broadcasting from her home.
"Like millions of Britons across the country, and as an over 70, I will be self-isolating and 'working from home'," she said.
"HealthCheck UK Live will offer a fantastic outlet to connect viewers and to remind us we can all fight this together."
The series "will directly address the concerns of viewers who are in isolation, offering tips on how to keep healthy and happy at home", Rippon added.
Producers said strict social distancing rules will be complied with, both on- and off-screen.
Mr Motivator, 67, who shot to fame in the early 1990s with a slot on GMTV, will be on hand to "offer expert advice to get people moving".
"Now more than ever it is important to keep our bodies and minds healthy," the fitness guru said.
"Everybody say: 'Yeah, let's get happy and be wicked at home!'"
The programme will offer audiences "information and company, to keep viewers upbeat while in isolation".
There will be tips on how to keep healthy, including how to boost the immune system, beat boredom and stay active.
The show comes after BBC Breakfast recruited the Green Goddess – fitness guru Diana Moran – to help people, especially the over-70s, keep active.
Ackerley said: "HealthCheck UK Live will offer support to audiences at home during these challenging times and I am delighted to be presenting the programme alongside broadcasting icon Angela Rippon, health expert Dr Xand, and of course Mr Motivator!"
The series will air for two weeks on weekdays at 10am on BBC One from Monday.
