[1] My older brother wants me to develop good habits when I exercise, so every morning before school, we work out together. [2] Each day he helps me to make sure I am performing my exercises correctly by observing me and giving me advice about my form and
technique. [3] Our routine takes only five or ten minutes, which sounds reasonable, but the truth is that it is a challenging workout. [4] We always
start with push-ups because they are my favorite exercise. [5] The purpose of push-ups is to strengthen your back and chest. [6] If we didn't do
them correctly though, our arms feel very sore. [7] Trust my brother's advice: it is important to place your arms under your shoulders for push-ups.
