This cheat works for defensive players only and allows you to bypass the actual bench press training but still get the 7 points.

Select 3 defensive players and choose to train the Bench Press on All-Madden difficulty. As soon as you see the player in the bench press animation (right after the help screen) hit the Start button and select Quit. Voila! All 3 players will have 7 points and you didn't have to do any of the work!
