Prune off all of the branches that are growing down. Prune them off at soil level. Keep four or five of the branches that are growing straight. You can prune a rubber tree to be a single stem plant or a bush. Since you already have a bush I would keep it that way.
When you prune wear some rubber gloves because rubber plants have a white sticky sap that will ooze from the cut. Be sure and use sharp pruners.
The plant could use a repotting into a good quality potting soil. Water the plant in. After repotting you may have to stake a few of the branches to hold the plant upright.
The plant is gangly because it is not getting enough light. The best place for a rubber plant is in an east window where it can get about 4-5 hours of light a day.
BTW, you can root the cuttings from the pruning. Stick the cuttings into moist soil and they should sprout roots.
Here is an article on caring for a rubber plant, albeit not from University sources: https://smartgardenguide.com/how-to-care-for-a-rubber-plant-ficus-elastica/
If this seems too much you can always toss this one and buy a new one!
Has the plant been losing leaves?
The stems are long and spindly because they don't have enough light. A southeast window will work. If south is all you have then I would move it so that it gets more light from the south window. If the south window has shears you might want to close them to filter the light. Move the plant into the south window for a couple of hours each day for a week or so; that will get it accustomed to the stronger light.
As winter sets in the south light is not as strong.
BTW you can put it outside in the summer; it will be very appreciative.
They like indirect light: North or East facing window is best.
