A swingable exercise bicycle mechanism includes a base frame, two fastening seats at the front and rear, two extension springs arranged symmetrically in pairs connecting with the fastening seats, at least one sliding shaft extending between and being supported by the two fastening seats, a slider arranged on the sliding shaft, and a buffer arranged between each of the two fastening seats and the slider. An exercise bicycle is secured onto the top surface of slider. When a user swings their body on the exercise bicycle, the slider causes the fastening seats to rotate, and simultaneously generate a torque in the opposite direction, which enhances the swinging effect of the exercise bicycle. By moving the user's body back and forth, the exercise bicycle applies reciprocating component forces, which causes shifting of the slider, whereby damping by the buffer device is overcome to achieve the effect of intense exercise.

A plank exercise assembly for performing a plank exercise includes a panel that has a curved portion that can be positioned on a support surface. A block is coupled to and extends perpendicularly away from the panel and a pair of foot pegs is coupled to and extending perpendicularly away from the block in opposite directions from each other. Each of the foot pegs has a respective one of a user's feet is positioned between the foot pegs and the panel to position the user's feet in a preferred orientation for performing a plank exercise. A pair of wedges is each coupled to the panel on an opposite side of the panel from the block. Each of the wedges has a sloped surface with respect to the panel that rests on the support surface when the panel is positioned in a ready position.

A bicycle simulator including a frame support portion for supporting a bicycle frame, the bicycle frame connecting front and rear wheels of the bicycle; and a base portion supporting the frame support portion. The frame support portion includes a first support bar having one end portion thereof fixed to the bicycle frame, a second support bar having one end portion thereof fixed to the base portion, and a connection portion for connecting the other end portion of the second support bar and the other end portion of the first support bar. The first support bar is connected to be rotatable about one axis with respect to the second support bar.

A frame lifting mechanism includes a base, a motor, a lead screw, a sliding member, a lifting member and a supporting shaft. The motor is connected to the lead screw, and the lead screw is fastened onto a transmission tube, allowing the transmission tube to move forward and backward while being driven by the lead screw. The sliding member is installed on a sliding track arranged on the base and connected to the transmission tube, allowing the sliding base to actuate with the transmission tube synchronously. A rear end of the lifting base is pivotally attached onto the base for support, and the supporting member uses its two top and bottom ends to be pivotally attached onto the lifting member and the sliding member respectively, allowing the supporting shaft to utilize the movement of the sliding member to drive the lifting member to move upward and downward.

A balanced support structure of an aerobics step contains: a body, a limitation ring, and at least one base. The body includes a step face and a receiving groove. The receiving groove has an opening, and the body includes a fixing groove. The limitation ring includes a circular orifice which has a large-diameter segment and a small-diameter segment, the small-diameter segment having a diameter that is less than the diameter of the large-diameter segment, and the large-diameter segment is in communication with the opening. The at least one base includes a holder, and each of the at least one base includes a column which has a spherical knob, wherein a diameter of the spherical knob is equal to or is less than a diameter of the receiving groove, and the diameter of the spherical knob is more than the diameter of the small-diameter segment of the circular orifice.

A direct-drive bicycle training system and methods of using the same are provided. The system includes a bicycle trainer that rests on a support surface and supports a bicycle frame in an upright manner with respect to the support surface. The bicycle trainer includes a stator, a rotor that rotates with respect to the stator, a cassette affixed to the rotor, a support frame supporting the stator, rotor, and cassette, and a resistance applying mechanism that operatively couples to a portion of a drivetrain of the bicycle frame and applies varying levels of resistance to the portion of the drivetrain. The support frame moves with respect to the support surface in response to a force applied to the drivetrain of the bicycle frame during use of the bicycle training system, generating a more natural movement of the bicycle and simulating on-road use.
