A floatation device is provided. In some embodiments, a floatation device is provided, comprising an inflatable ring composed of a transparent material, wherein the inflatable ring includes: an outer air chamber having a first valve for inflating the outer air chamber; an inner air chamber having a second valve for inflating the inner air chamber, wherein the outer air chamber and the inner air chamber are not in communication; a cut through the outer air chamber and the inner air chamber of the inflatable ring that forms opposing ends of the inflatable ring; and a plurality of fasteners placed on a top surface and a bottom surface of the outer or inner air chamber for detachably connecting the opposing ends of the inflatable ring.

An exercise machine. The machine comprises a frame with front and rear upper support beams. Guide rails span between the two support beams and are connected thereto. Right and left handles are configured to slide back and forth along the length of the guide rails between the front and rear support beams. During operation of the machine, a user grabs the handles and moves them back and forth in a swinging motion that mimics traversing a set of monkey bars. The guide rails may be arranged in a non-parallel configuration to provide a more natural path for the user's hands during operation and to reduce unwanted stress on the user's shoulders by limiting handle movement along the path to accommodate a more comfortable range of motion.

An exercise machine for performing dip exercises, having: a stationary main frame; first and second mounting brackets connected to the stationary main frame; first and second dip handle assemblies connected to the mounting brackets, each dip handle assembly having a first exercise arm, a first stop plate, and a first arm mount hub, wherein the first and second dip handle assemblies are each configured to be converted between an exercise position and a storage position while connected to the exercise machine.

A vertical knee raise machine that is portable, which can be folded into a compact unit for storage but than be quickly and easily set up for use. The machine includes a foldable tripod base and folding arms to allow it to be folded up for ease of storage.

An exercise device includes an elongate guide having a longitudinal dimension between spaced apart ends. A pair of foot supports are slidably mounted on, and relative to the elongate guide. A body engaging member is adjacent a side edge of the elongate guide and is engageable by an individual using the device. A linkage system is connected to the pair of foot supports and to the body engaging member through rotatable connections, with the rotatable connections permitting interconnected movement of the body engaging member and foot supports in the same longitudinal direction along the longitudinal dimension of the elongate guide. Preferably, an adjustable rail also is provided by a pair of rotatably mounted arms.

Methods of teaching and learning bicycle riding skills are disclosed, including training a student to ride a bicycle comprising positioning a student on a bicycle at the top of an inclined surface with a slope in a range of 8 to 15 degrees and a distance of at least 30 feet, wherein the student straddles the bicycle's seat such that the student's feet engage the inclined surface and the student's hands engage the bicycle's hand brakes. The student releases the brakes and lifts his/her feet from the inclined surface. Under angular momentum, the bicycle moves down the inclined surface while the student steers the bicycle. The bicycle is returned to the top of the inclined surface and the steps are repeated. The student also learns to pedal the bicycle using the inclined surface with similar repeatable steps. Other skills such as starting the bicycle with the pedals are taught.

A detachable stabilizing support system for use on an exercise machine, such as a functional trainer exercise machine, has adjustable support positions and is capable of being configured between an exercise position and a more compact storage position.

A garment attachable to an exercise or therapeutic apparatus that is capable of elevating the user slightly above the ground, reducing potential for injury and strain by shifting the user's weight to the frame of the apparatus. The garment is incorporated into the apparatus by comprising panels under the buttocks and around the thighs, providing balance and lifting the user comfortably in conjunction with the frame. A low-friction plate is positioned under the user's feet so that the user can ambulate freely while held in place by the frame.

A muscle activation system including: an inclined platform for a user to stand on; a rigid upper body user support frame attached to the inclined platform for supporting the upper body of a user standing on the inclined platform; a base, coupled to the inclined platform, the coupling allowing relative orientation motion between the base and inclined platform. The platform adapted to undergo a precession like motion around a central point so as to circumferentially move a user's upper body, when supported by the rigid upper body user support frame, substantially through an arc around a central point.
