Levels of certain hormones, such as those produced by the thyroid gland, can be factors in depression. In addition, some symptoms of depression are associated with thyroid conditions. The same is true about conditions related to the menstrual cycle, such as premenstrual syndrome (PMS), perimenopause, and menopause.
The bench press is a compound exercise that is performed with a barbell or dumbells and weight bench. During this exercise, you lift the wieght to and from the chest from a face-up position. Being that this is a compound exercise, it works multiple muscle groups at once.
Doing these things makes your chest push most of the weight and you get a better contraction which helps to build a big and strong chest. Flat bench press is called flat bench because the bench is flat not because you are supposed to have a flat back. Get your facts straight.
