This is astonishingly true.

What we must now do is to supple him, to quicken his co-ordination, to improve his poise, and to put his trunk and thorax into better shape.

We must give him endurance, quickness of response, and resistive force.

This, therefore, being our problem, we eliminate the arm and leg exercises and go directly for the trunk and thorax.

We must quicken co-ordination and improve the man's rapidity of response to command.
