## Do you bench press correctly?

Here are some of the steps you need to keep in mind to make sure you exercise correctly. First of all you need to maintain a tight grip with the bar and keep your chest in thoracic extension the whole time you move. This will create more tension in your lower arms and upper back. Make sure you keep your elbows at an angle of 45 degrees from your side. Don’t forget to breath while taking the weight. While lifting you need to keep your back, hips and glutes contracted. When you end the movement, don’t forget to lock out your elbows but to continue to maintain the thoracic extension.
