LOS ANGELES (thefutoncritic.com) -- Lifetime is set to overhaul its Monday lineup come January, network sources confirmed to the site over the weekend.

The new block, which launches January 5, will consist of repeats of "How I Met Your Mother," "Reba" and "Wife Swap" as well as new episodes of "Rita Rocks" and its latest original series "DietTribe."

The latter, which will anchor the night at 10:00/9:00c, is an hourlong reality series about five best friends who "make a pact to lose weight together and agree to a 90-day weight loss program" with the help of a personal trainer and a therapist.

Back-to-back episodes of "Mother" will open the night at 7:00/6:00c followed by "Reba," "Rita Rocks" and "Wife Swap."

"Rita," which recently got picked up for seven additional episodes (read the story), will migrate from its current Tuesday, 8:30/7:30c home.

To recap:

Mondays (starting January 5)
7:00/6:00c - "How I Met Your Mother" (Repeats)
