I cannot see how the strength of his muscles, the arms and the heart, are two very different things. Perhaps it is the strength of his feelings for the horse, a living thing - assuming the horse was alive after the slide, that is being referenced.

The usage can be called a semantic syllepsis, or zeugma based on answers to similar questions.

  • Strength of one's heart is a case of figurative language. He "had the heart to save the horse" – David Coffron Sep 28 '18 at 18:22
