Hello,
This is a big day. I attempted it a few years ago but was zonked after descending Russell (Russell was my primary objective after climbing Whitney a few times previously). I went up Russell East ridge then down the Fishhook Arete descent route (south face?)
Next would be up the Whitney North Slopes and down the Whitney trail.
Or Vice versa if you want to summit Whitney first.
Here is a previous post withthe route referenced:

The crux will be the North Slopes of Whitney - most people encounter 4th class sections and the route fining is a bit difficult and the route not traveled very frequently.
