"Keep your elbows in fairly close to your sides; fists loosely closed and forward, a little higher than your elbows.

Now, all runners come in." Gathering the squad about him, and demanding close attention, Mr.Luce showed the pose of the body at the instant of starting.
"Now, I'm going to run to first and second," continued the coach.
"I want every man of you to watch closely and catch the idea.
You note how I hold my body---sloping slightly forward, yet with every effort to avoid cramping the chest.

Observe how I run on the forward part of the ball of the foot---not exactly on the toes, but close to it.

See just how it is that I throw my feet up behind me.

And be very particular to note that I keep my hands and arms in just this position all the way.
