Explain why head circles and arm circles are considered dangerous exercises.

describe a potential risk that distinguishes hurdle stretches performed with the leg pointed back from hurdle stretches with the leg inside.

Both head circles and arm circles involve stretching with motion. These stretching exercises risk serious injury to the muscles of the neck and shoulders if the motions are not trictly controlled. When the head goes back, it hyperextends the neck, which is dangerous; despite not involving bouncing, arm circles are a ballistic exercise and should not be performed.
