          A KNEE





          Yes, your knees

          can bend
          over your toes

          during squats.

          Here’s why.


             f you’ve ever had a barbell
             on your back, then we’re
             sure that someone—be it a
             doctor, trainer, or fellow
         I gym bro—has told you that
          your knees shouldn’t pass
          your toes when you squat.
          This is a lie. Not only is
          keeping your knees behind
          your toes biomechanically
          impossible, but it’s healthier
          to let them track over. We’ll
          get into that in a minute, but                           WHAT
          how did this myth start?                                GIVES?
                                                                  Not only is
          THE ORIGIN                                         keeping your knees
                                                              behind your toes
          The roots of this fallacy can

          be traced back to a study
                                                              impossible, but it’s
          conducted by Duke University

                                                                  them track

          during a squat (knees behind
          the toes) led to less shearing
          force on the knee. While this
          is technically true, increased
          force alone is not a marker for
          pain. Adequate stress, after all,
          is what causes muscle growth
          and improved cardiovascular                   athletes tracking their knees
