I do the same thing on weekends that I do every day, but as a solopreneur who is single without kids and works from home, I have that flexibility. I typically laze around most mornings, meditation, cooking, reading, writing, long hot shower, exercise etc. Then I spend between 3-6hrs on productive things (revenue generating or in pursuit of revenue generation). Sometimes that will go much longer, depending on how into it I am, but rarely ever below 3hrs.

As mostly all of my friends are only fully available on weekends, that's usually the only thing that is different is that these activities that are in person usually only take place then.

The weekend as a thing is a very modern invention. I've found that i'm much more relaxed day to day and no longer have to "look forward" to a weekend for a break. I take those breaks as I need them. It did/does take a lot of cultivated discipline to make this work though, if you hate your work that's going to be a problem for this lifestyle.
