Perhaps you should try some spelling variations:
training decreases » training increases (Expand search)
decrease training » increased training (Expand search), disease training (Expand search), release training (Expand search)
decrease walking » increase walking (Expand search), decrease during (Expand search), decrease lodging (Expand search)
walking decrease » walking decreases (Expand search), warming decreases (Expand search), taping decrease (Expand search)
decrease costs » decreasing costs (Expand search), decreases post (Expand search), disease costs (Expand search)

decrease at » decrease akt (Expand search), decrease and (Expand search), decrease in (Expand search)
at decrease » rate decrease (Expand search), that decrease (Expand search), and decrease (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease walking decrease training decreases ) OR ( decrease at decrease costs object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease walking decrease training decreases ) OR ( decrease at decrease costs object ))*.
