Abstract: An exercise machine may include a frame with foot pedals mounted thereon and a seat having an inflatable bladder whereby the user may undertake a cardiovascular workout and a core workout of abdominal and back muscles.

Abstract: An exercise machine may include a frame with set of foot pedals mounted thereon. A seat-receiving space is defined by the frame rearward of the set of pedals and a seat that is in the form of an inflatable bladder is received within the seat-receiving space. The inflatable bladder is retained within the frame in such a way that the bladder is able to move within the frame when the exercise machine is used. A seat back extends upwardly of and adjacent the inflatable seat and supports a user's back while the user is seated on the inflatable seat. Left and right arms are secured to the frame and extend respectively to the left and right of the inflatable seat. The user may undertake a cardiovascular workout and a core workout of abdominal and back muscles using the exercise machine.

Abstract: An exercise device and a method of exercising includes one or more undulation members, such as ropes, which a user undulates, which may cause an elastic line to stretch and/or a travel line to travel around one or more pulleys. The exercise device is configured to allow exercise using undulation members in a relatively small space.

Abstract: An transportation cycling apparatus is provided having an inflatable seat securely retained by a seat retaining mechanism. The inflatable seat is spherical in shape and made of polymers to actively support a user. The cycling apparatus further having a frame, handlebars, brakes, pedal assembly and a sprocket and chain powering mechanism.

Abstract: An exercise machine includes a frame with foot pedals mounted thereon and a seat having an inflatable bladder whereby the user may undertake a cardiovascular workout and a core workout of abdominal and back muscles. A sensor may be used to sense the degree of compression of the inflatable bladder when a person sits on the inflatable seat whereby the internal pressure of the bladder may be adjusted accordingly. The frame may have two sections which are detachable so that one of the sections and the inflatable seat serve as a seating assembly when detached.
