Women regularly seek to improve the appearance of their legs and butt, and do not pay much attention to the upper body, which includes arms, pecs and back. Perhaps it is from the belief that the body will begin to take a “masculine” form, but take off that fear!
The only way to get to that level is with a very strict routine and diet. Exercising your arms two or three times a week won’t leave you looking like the Hulk himself; on the contrary, it will help you eliminate sagging.
Look at these excellent routines that you can do in the comfort of your home and with which you will get firmer and stronger arms.
