FIELD OF THE INVENTION
The invention is a stationary exercise apparatus designed to allow one or two users to execute a wide variety of bodyweight exercises including pull-ups, dips, crunches, leg raises, and inclined push-ups.
BACKGROUND OF THE INVENTION
Some bodyweight exercises can be performed without any equipment, including isometric exercises and pushups, while other exercises are enhanced or made possible with the incorporation of exercise equipment. Exercise equipment is commonly found in gyms or in parks. Home exercise equipment is also popular, though space constraints often mandate that the equipment be foldable and movable for storage when not in use. Some bodyweight exercises requiring equipment, such as pull-ups, can be performed in a user's home through the installation of a pull-up bar, such as in a doorframe, but there is a need for a sturdy apparatus that permits the user to undertake a broad range of bodyweight exercises, while being compact, easy to set up, easy to fold and transport for storage.
SUMMARY OF THE INVENTION
The present invention discloses an exercise apparatus that is ideal for home use, as well as being suitable for gyms, physical therapy, and other facilities. The apparatus is comprised of a left base frame and a right base frame, which when set up for use is approximately 48″ long, 28″ wide, and 48″ high. When the apparatus is folded for storage, it is approximately 48″ long, 10½″ wide, and 48″ high.
The exercises that can be performed are almost limitless and include exercises that work out the chest, back, legs, arms, and abdominal muscles. The preferred embodiment of the present invention can be utilized by a user in a simple and effortless manner to perform total body exercises at virtually any location in a manner which is not only quick, easy, and effective, but can be performed with a minimal amount of training and/or experience after initial purchase or acquisition of the apparatus.
