Looking at the horse o a flat surface, standing squarely, look for any 
crookednes in the muscle develpment. This is done by walking around the 
horse and looking for large oversize muscles in relation to their mirror 
muscle group on the opposite side. For instance looking from the rump to 
the withers the muscles may be larger on one side of the withers than the 
other. That indicats over work on one side by the from leg muscle groups. 
Also look for the position of the knees and chest  muscles by looking 
from the side. Look for chest muscle imbalance from on side to the other 
and differences in joint position relationship. For instance one knee may 
be higher than the other or one side of the chest is further forward than 
the other. 
    
   This is  avery basic run down on what to look for.
