“…The “bird dog” is one of the most popular core exercises [ 1 , 2 ], is commonly prescribed in lumbopelvic rehabilitation interventions [ 3 ], and is considered one of the most effective therapeutic exercises for the prevention and treatment of low back pain [ 4 ]. Several electromyographic (EMG) studies have evaluated the activity of core muscles during the bird dog exercise [ 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. Overall, these studies provide evidence that this exercise primarily targets the lumbar and hip extensor muscles and reported activation levels of 21–56%, 23–42%, 21–42%, 23–46%, 22–38%, 21–35%, and 4–15% maximum voluntary contractions (MVIC) were obtained for the gluteus maximus, gluteus medius, hamstrings, lumbar multifidus, longissimus thoracis, external oblique abdominis, and rectus abdominis, respectively.…”
