Abstract: A modular fitness bed comprises a first post, having a first end and a second end coupled to a second post, having a first end and a second end through a first top rail. The first end of the first post is coupled to the first end of the second post through a first top rail. A third post has a first end and a second end coupled to a fourth post, having a first end and a second end. The first end of the third post coupled to the first end of the fourth post through a first top rail. The first post is coupled to the third post through a first support bar and the second post is coupled to the fourth post through a second support bar. A set of monkey bars extends along a length between the first top rail and the second top rail. A first bottom rail extends from the second end of the first post to the second of the second post and a second bottom rail extends from the second end of the third post to the second of the fourth post. A mattress support facility connected to the posts and below the monkey bars.

Abstract: A fitness activity apparatus has a frame having four vertical posts, the vertical posts comprising a left rear post, a right rear post, a left front post, and a right front post, the left rear post and right rear post being connected by a rear lateral bar, the left front post and right front post being connected by a front lateral bar, the left rear post and left front post being connected by a left side bar, the right rear post and right front post being connected by a right side bar, the left side bar and right side bar being at a common level to provide a support platform configured to support a circular weight plate having a selected plate diameter, and the rear lateral bar positioned at a first vertical level and front lateral bar being positioned at a different second vertical level.

Abstract: An exercise apparatus for attachment and use within a door frame includes a pair of elongated frame elements with each having apertures configured to receive various types of cross bars. The frame elements are designed to be secured to vertical portions of a door frame without interfering with passing through the doorway or closing the door. A cross bar having a length greater than the door width is configured to be received within corresponding apertures among the frame elements. A cross bar has a retractable spring pin protruding from the bar so that the spring pin may engage a frame element to limit axial excursion of the bar. Two such spring pins may be included in the bar, so that with the frame elements including apertures having pin-receiving pockets, one type of bar may rotate freely while another type of bar is prevented from rotation.
