Functional strength: work on stamina (endurance plus strength). Do the exercises that require some athletic skill and timing. Like clean & jerks, snatches and overhead movements in general. Use DB's in some of these exercises also. Include DL's, and step-ups with added weight. Get away from lower, heavier sets and up the reps from 12 to 20+ on these exercises.
Rope climbing is a superior exercise that is rare for BB'ers. Keep the legs extended out when doing them. If you have gymnastic rings than start learning how to use them. Dips and at times with the legs extended out also. SS SLDL (back straight throughout..no lower that the height of the '45's) with heavy ab work. And you may have to work the obliques also. Lower back, ab wall and the obliques can be the cornerstone for functional strength. Good Luck.
