Incline Bench Press
Incline bench is an alternative exercise to the flat bench that places the back of the bench at a 15 to 60 degree angle. The general consensus seems to be that an incline of 15-30 degrees will put optimal stress on the upper pec while keeping the recruitment of the front delts to a minimum.
Most incline benches that cannot be adjusted usually have a 45 degree angle. If you have an adjustable bench, the higher the back is angled, the more the front delts will be involved.
Any bench you use that is higher than a 45 degree angle works mostly anterior deltoids. Because of this, I do not consider this movement an incline bench press.
