Free weightloss/ workout programs

Does anyone have any suggestions for weigh loss programs or like workout programs or videos on YouTube? Anything that does not cost money. I subscribed to Kayla Itsines bbg app but because I’m always so busy it’s become a waste of money. So something free but effective would be great.
