A helpful tip: When choosing your grass seed look for the germination rate on the label. This is the percentage of seeds that germinated in lab tests. The higher the better. A rating of 90-95% is ideal.
The bench press is a compound push exercise that activates a number of upper-body muscle groups. These groups include the pectorals, deltoids, triceps, biceps, trapezius and core muscles. You can shift the emphasis of the press to specific muscle groups in that span by widening or narrowing your grip on the bar, by replacing a barbell with dumbbells, or by performing the press on an inclined or declined bench.
The best reason to bench press isn't necessarily to build purty pecs but for hormonal release. Big bang movements like the bench press increase Testosterone and growth hormone concentrations, which will help hypertrophy everything, not just your chest and triceps. So if the goal is to grow, then bench. But if you also wish to target the muscle fibers of the pecs more directly, here's a few other suggestions.
