air in the room as possible. It is an excellent plan to face an open
window if we practise morning and evening gymnastics.

There are many exercises that can be performed with no apparatus

until it becomes a habit with us. Most people acquire a faulty habit
of breathing and only use a small part of their total lung capacity.

more than he, have, in wrestling and feats of strength, found that the
