The Bench Press is a full body, compound exercise. It works your chest, shoulders and triceps most.
It’s not surprising that the bench press is such a popular move. Once you’ve mastered the basic movement pattern you will see rapid progress in how strong you are.
This exercise alone, will improve your overall upper body strength. in less time than doing an isolation exercise for each muscle group.
Make sure that you are not holding your shoulders in an awkward position. Be sure to have a natural spinal curve. You do not want to have your lower back flat on the bench, but you do not want to force it to curve too much either.
Grip the bar tightly. Do not use a thumbless grip, the bar can slip from your hands and crush your face. Wrap your thumbs around the bar to secure it.
Avoid bending your wrists. Straight wrists will prevents wrist pain, and will give you more stability and strength performing the press. You should place the bar in the heel of your hand (directly above your wrist). Notice that if you place the bar more towards the base of your fingers or in your palm, your wrist gets bent back.
Don't flare your elbows 90° on your sides when the bar is down. This puts too much stress on your shoulders, and might cause pain and injuries. Keep the elbows at about 75° from your body. You can ensure a good position if you lower the bar to touch your mid-chest, and not the upper-chest or neck area.
Where you position your hands will affect which muscle group you work most. Widen your grip slightly to increase the amount of pectoral muscles (the chest) involved in this exercise, but will be more difficult on your shoulders. Bring your grip in slightly will engage your triceps more, but will be less effective for the chest. For a standard bench press, opt for the medium grip.
For a good medium grip width, make sure that when the bar is lowered, your forearms are vertical to the floor, and not angled.
Make sure to use weight you can manage, you don't want to get stuck under the bar not being able to lift the barbell. If its your first time, try to lift the bar without weight on, it is quite heavy on itself. It is also a good idea to have a spotter by your side.
