Bobbing, Bouncing, knees out, and elbows out. There are a few simple ways to combat these common cycling problems.
The first is a combination of core work and stretching. This will not only allow you to keep yourself more stable while riding, it will also stop a number of the muscular imbalances that could lead to your knees or elbows coming out of line.
The second is making sure your position on the bike is correct. For example if your saddle is too low you might find your knees coming out of line and you might bounce on the saddle at higher cadences.
