Richard Francis Burton,
A New System of Sword Exercise for Infantry…
(1876)
“ The recruits' muscles soon become fatigued by the unusual and monotonous exercise, causing them to remain too long in one position; the easiest way to relieve them is to change front, making the left leg stand on guard and lunge, as a left-handed fencer would do. This double practice is as useful and recommendable in fencing and broadsword play as in bayonet exercise: it gives additional balance to the body, it equalizes the muscular strength of both sides, and it makes the soldier feel that if his right arm be disabled he can still depend upon his left. ”
