The Definition of Isosceles Stance
There are two basic variants of the Isosceles stance, the
Traditional Isosceles and
Modern Isosceles stance.
In both Isosceles stances, the feet parallel pointing toward the target and are roughly shoulder width apart.
Both arms are stretched almost equally forward with the gun centered forward, creating the triangular shape which gives the stance its name.

The Chapman stance uses the same push-pull tension which defines the Weaver,
but instead of both elbows being bent, the gun side elbow is held straight and locked in place.
Assuming a right-handed shooter, the right arm is punched straight out, while the left elbow is bent and the left hand pulls back to provide tension. As a result of this change, Chapman gets its stability
from both muscle and skeletal support. This makes it a little more friendly than Weaver for those who lack upper-body muscle strength.
