Cambered bar benches
will strengthen your chest, which
will improve the start of your bench press.  Depending
on the depth of the camber of your particular bar, you
may need to shorten it by adding boards to your chest.
A 2"-3" stretch past chest level is a general
recommendation.  The bar in the photo has a 5" camber
and boards are added to cut the stretch down to 2".
Too much stretch can be rough on the shoulders of some
people as well as their pec/delt tie-ins.  Some people
do cambered bar benches with a touch-&-go style,
others pause their reps.
