Many Russians that you see in captivity have accelerated growth unfortunately. It's very easy to tell a tortoise which has been fed too quickly when compared to a wild Russian. Russians tend to 'pillow' more than pyramid like other tortoises do. In the wild they only eat for around 3 months of the year, so it's easy to see how they can grow so rapidly in captivity when they are eating for usually 9 months out of 12!

The above pic (found on google) is an ideal example of how smooth a russian should be, below (also found on google) is an example of a russian grown much too quickly;

If you look at the 'yellow' raised scutes, then that is all excellerated growth. The tortoise has obviously been over-fed or not hibernated to achieve this look.
Unfortunatley, all that you can do to 'reverse' this if your tortoise is looking a bit like that is to start feeding the right amount and hibernating them. They aren't likely to suddenly become smooth, but the effects of fast growth will be kept to a minimum.
Russians are burrowing species so should be outside for most of the year, and when inside should have a large deep enclosure where they can construct a burrow. When they are outside they will usually create their own little burrow, which would usually be south facing.
If you ask Nicely, Sue, (Wizzasmum) will post pics of her enclosure and explain a little more about them... her russians are lovely and smooth and their enclosure is excellent. Very natural, and her hard work was rewarded 2 years ago, when her russians started laying fertile eggs for her. The babies are gorgeous and smooth as the day they left the egg.
