Exercising implements and methods of use for performing muscular stretching exercises, respiration exercises, and resistance training

An articulating bench configured to support a user, comprising:

• a frame structure extending longitudinally about a first longitudinal axis, the frame structure sized, shaped, and constructed to support a back supporting portion and left and right leg supporting portions and the user lying thereon;
• the back supporting portion pivotably attached with the frame structure about a first horizontal axis perpendicular to the first longitudinal axis, the back supporting portion fixable at a first range of angles with respect to the frame structure, the back supporting portion sized, shaped, and constructed to extend underneath the entire length of and support the user's back and head when the user is lying on the articulating bench;
• the left leg supporting portion pivotably attached with the frame structure about a second horizontal axis perpendicular to the first longitudinal axis, the left leg supporting portion fixable at a second range of angles with respect to the frame structure, the left leg supporting portion sized, shaped, constructed, and located to extend underneath the entire length of and support the user's left leg and left foot when the user is lying on the articulating bench;
• and
• the right leg supporting portion pivotably attached with the frame structure about the second horizontal axis, the right leg supporting portion fixable at a third range of angles with respect to the frame structure and movable independently of the left leg supporting portion, the right leg supporting portion sized, shaped, constructed, and located to extend underneath the entire length of and support the user's right leg and right foot when the user is lying on the articulating bench;
• wherein the frame structure comprises:
• a centrally-located central portion to which the back supporting portion and the left and right leg supporting portions are pivotably attached;
• an adjustable back support linkage configured to fixably support the back supporting portion at the first range of angles with respect to the frame structure and comprising:
• a first member pivotably attached at a first end with the frame structure and extending to a second end slidably attached with the back supporting portion;
• a second member with a first end selectably attachable at different longitudinal locations on the frame structure and extending to a second end slidably attached with the back supporting portion;
• an adjustable left leg support linkage configured to fixably support the left leg supporting portion at the second range of angles with respect to the frame structure and comprising:
• a third member pivotably attached at a first end with the frame structure and extending to a second end slidably attached with the left leg supporting portion;
• a fourth member with a first end selectably attachable at different longitudinal locations on the frame structure and extending to a second end slidably attached with the left leg supporting portion;
• and
• an adjustable right leg support linkage configured to fixably support the right leg supporting portion at the third range of angles with respect to the frame structure and comprising:
• a fifth member pivotably attached at a first end with the frame structure and extending to a second end slidably attached with the right leg supporting portion;
• and
• a sixth member with a first end selectably attachable at different longitudinal locations on the frame structure and extending to a second end slidably attached with the right leg supporting portion.
