Sit upright on the exercise bike seat with back against the backrest, feet secured on the pedals, hands gripping the handlebars, and torso positioned perpendicular to the pedaling plane

Adjust the seat height so knees are at approximately 90 degrees when pedals are at the lowest point, ensure core is engaged, and prepare for the pedaling motion with controlled breathing

As you pedal backward, flex the abdominal muscles and draw the knees toward the chest while maintaining an upright posture, allowing the lower back to round slightly as the knees approach the torso

Extend the legs forward to complete the pedal stroke, return to the starting position with controlled extension, and repeat the motion in a continuous cycling pattern while maintaining abdominal engagement throughout
