The push press is a modified overhead (military) press performed in the standing position. Start with your knees bent and hips lowered, the weight is about collar bone level. As you push the weight up with your shoulders, straighten your legs and drive with your hips. Lower the weight back to shoulder/chest level, then bend back to the starting position.
This will add some body english, allowing you to use more weight. The vets might have a better idea as to what percentage of your shoulder press weight you should use, but I advice you to start off as you normally would with a shoulder press, and concentrate on moving the weight up fast. Once you find your grove with the movement, up the weight, amaze yourself with how strong you'll feel doing this.
