Stretching device
View Patent ↗A stretching device that enables a user to employ the mechanical advantage of a multi-pulley system while performing various, prolonged muscle stretches; the stretching device including a first anchor assembly, a second anchor assembly, and a motion transfer line. The first motion transfer line has a first anchor body and a first motion transfer pulley; the first anchor body being attached to the user and the first motion transfer pulley being coupled to the first anchor body. Similarly, the second motion transfer line has a second anchor body and a second motion transfer pulley; the second anchor body being attached to a stationary object and the second motion transfer pulley being coupled to the second anchor body. The motion transfer line is terminally attached to the first anchor body and is trained around both the first motion transfer pulley and the second motion transfer pulley.

the first body fastener and the second body fastener being terminally positioned opposite each other along the first strap.
7. The stretching device as claimed in claim 6 comprising:
the first body fastener engaging the second body fastener, wherein the first strap is formed into a loop.
8. The stretching device as claimed in claim 6 comprising:
the first anchor point and the second anchor point being positioned in between the first body fastener and the second body fastener.
9. The stretching device as claimed in claim 1 comprising:
the second anchor assembly comprising a second detachable pulley-fastener; and
the second detachable pulley-fastener being connected in between the second anchor body and the second motion transfer pulley.
10. The stretching device as claimed in claim 1 comprising:
the second motion transfer pulley being pivotally coupled to an arbitrary anchor point from the second plurality of anchor points.
11. The stretching device as claimed in claim 1 comprising:
the second anchor body comprising a first strap fastener and a second strap fastener;
the first strap fastener and the second strap fastener being adjacently connected to the second strap; and
the first strap fastener and the second strap fastener being terminally positioned opposite each other along the second strap.
12. The stretching device as claimed in claim 11 comprising:
the first strap fastener engaging the second strap fastener, wherein the second strap is formed into a loop.
13. The stretching device as claimed in claim 11 comprising:
the second plurality of anchor points being positioned in between the first strap fastener and the second strap fastener.
