Physical training apparatus for holding a person's feet when performing sit-ups

摘要

Physical training apparatus for holding a person's feet while the person lies supine on a floor with his or her feet facing a closed door, includes a generally trapezoidally shaped foot bar support member which has a base portion with a planar bottom surface facing toward the floor. The support member also has a first surface which extends normal to the floor and faces toward the person, and a second surface which is inclined upwardly from the base portion toward the first surface and which faces toward the door. An extension member extends from the base portion toward the door to pass through an opening between the door and the floor, and to engage the door so as to prevent the bar support member from moving away from the door. A wedge-like space is thereby formed between the bar support member and the door, and a locking wedge is provided for insertion in the wedge-like space to fix the bar support member against movement toward the door. Accordingly, the apparatus dispenses with the need for another person to hold the feet of the person when performing sit-ups.
