Biceps and triceps combo

Person 1 works on: Biceps
Person 2 works on: Triceps
Stand face-to-face, three feet away from each other, with feet shoulder-width apart. Person 1 holds the center of the exercise band, palms up, with hands shoulder-width apart, arms straight down and elbows close to the waist. Person 2 takes one end of the band in each hand, palms facing each other, with elbows at her waist and forearms forming a 90 degree angle with her body. On the count of one, person 2 pulls on the exercise band to bring her hands down to her side until her arms are straight but not locked. At the same time, person 1 bends her arms to bring the band toward her shoulders, keeping her elbows glued to her waist and her wrists in line with her forearms. The exercise band will then be extended since person 1 and 2 are pulling in opposite directions. On the count of two, slowly regain the starting position and repeat. Do two sets of 15 reps, alternating positions between sets.
