The Larry Scott Shoulder Press was developed by Vince Gironda to bring up Larry Scott's lagging shoulders for the Mr. America Contest. The rest is history.
This press is a little like the Arnold press except that the starting position is more conservative and much easier on the lower back.
Start with Dumbbells resting on top of your shoulders, elbows in front of body keeping pinky fingers facing up at all times. Press Dumbbells starting from in front of your neck at the bottom to behind the neck at the top.
Press straight up from shoulder width. Do not bring dumbbells together clanging at top. Don't lock out elbows at top. This keeps Triceps from taking over the weight and relaxing the delts at the top.
Look up when dumbbells are at bottom and look down as dumbbells reach top to keep traps out of movement.
Larry uses the middle 3/5ths of the movement never totally extending the arms or lowering them again to the shoulder. This keeps constant tension on the delts. In most if not all exercises Larry advocates never letting tension off even if it means a reduction in the weight used.
The other fact when training with Larry is that you always, always, totally isolate the muscle being worked.
