What are good chest workouts that put the least amount of pressure on your neck?

Bench workouts. Supine on a flat bench or inclined with weights that do not cause you to strain by lowering the total amount of weight but then increasing the number of repetitions per each of the 3 sets. Your head should be resting supported on the bench as well. Machines are fine as well as long as you keep the weight load lower & compensate by increasing the reps per set.
