Standing upright with one foot off of the floor, attach the band so that it is above the level of your head to a door or any attachment you may have. Make sure there are equal lengths to each side of the band. Place your arms to the side of your body. Your upper arm should never move through the exercise. ONLY YOUR LOWER PART OF THE ARM. Take each handle and start by having your elbows at a 90 degree angle. slowly extend one arm so that it becomes completely straight and pointing downward. Make sure to tighten and squeeze the back part of your arm (Tricep). Slowly come back up to that 90 degree angle and repeat, making sure to do the same amount with the other arm until you complete the set.
