Here's the important part. At the top, when your hands come together, squeeze your chest muscles as hard as you can for one full second. Really feel that contraction along your collarbone. Then slowly lower the handles back down, and take two full seconds to control the weight on the way down. Let your arms spread back out, and go slightly behind your body to get a good stretch. That's one rep. Do three sets of 15 to 20 reps, and rest 60 seconds between sets. If you can't feel your upper chest working, the weight is too heavy.
