Portable dual incline adjustable resistance abdominal muscle exercise machine

Abstract

An abdominal muscle exercise machine of a push-pull type that includes an elbow sliding support plate with handle bars; a knee sliding support plate with swiveling knee cups; elastic resistance bands attached between the elbow and knee support plates and the end stabilizer bars; parallel sets of shafts at the front and rear end of the machine connected to the sliding support plates; a center rod with support legs to raise it off the ground; quick release clamps attached to the parallel shafts; and end support rods with end caps at the front and rear end of the machine. The machine has a dual incline angle for both the elbows and knees to pull and push against during exercise and may be adjusted in range of motion using quick release clamps. The machine may also be easily folded closed for storing in a compact space.

Description

FIELD OF THE INVENTION[0001]This invention relates to the field of abdominal muscle exercise apparatus. More particularly, the present invention relates to an exercise machine that uses a dual incline with elastic bands to create an adjustable resistance push-pull exercise targeted specifically to building the abdominal muscle group in a kneeling position.BACKGROUND OF THE INVENTION[0002]Exercising the abdominal muscle group has been traditionally performed either with or without the assistance of an apparatus. The common “sit up” or abdominal crunch is performed by laying down flat on the floor with knees bent and facing up. The weight of the upper torso is used as resistance to contract the abdominal muscles during raising the upper torso until the elbows make contact with the knees. Although performing abdominal exercise without machine assistance may be beneficial, it may also cause damage to the body if not performed correctly. Further, the effectiveness of the exercise also va...

AI Technical Summary

Benefits of technology

"The present invention provides an abdominal push pull exercise machine that is portable, low cost, and affordable compared to existing machines. The machine is made from stainless steel, rubber, and plastic, and provides fixed support for the knees and elbows. It also allows the user to easily adjust the resistance and range of motion of the machine."

Problems solved by technology

Although performing abdominal exercise without machine assistance may be beneficial, it may also cause damage to the body if not performed correctly.

Abdominal muscle exercise equipment commonly used in physical fitness centers today range in complexity from basic static inclined benches with adjustable inclination angle that hold the feet locked together to more complex machines that have one or more moving components that assist in maintaining a uniform and consistent range of motion.

There are several common problems that have been observed by this inventor in the current state of the art of abdominal exercise machines.

The first problem is that abdominal exercise machine designs are normally not designed to be portable.

A second common problem observed is those most abdominal exercise machines are not affordable for the average consumer to purchase for home use.

As a result, most people who use abdominal exercise machines do not have their own machine for home use but instead spend money at fitness centers and use shared abdominal exercise machines at fitness centers.

A further common problem with exercise machines shared in fitness centers is poor hygienic upkeep caused by users throughout the day who do not properly clean off their sweat from the machines after use.

A third common problem is that current abdominal exercise machine designs do not provide adequate fixed support for the knees and elbows throughout the entire range of motion during each exercise repetition.

One byproduct of the lack of fixed support of knees and elbows is that users can cheat during their workouts by decreasing the range of movement when doing multiple repetitions.

A fourth problem seen is that most abdominal exercise machines typically do not allow the user to easily adjust the resistance of the machine during exercise.

Those machines seen in the current state of the art that do have variable resistance often use bulky rectangular pinned plate and cable pulley designs that are bulky, lack portability and are furthermore too expensive to purchase for the average person.

A fifth problem in the current art is that the adjustment of the range of motion is typically made difficult through the use of bulky components such as shear pins.
