Pull-ups and chin-ups are a popular form of exercise performed with a pull-up (or chin-up) bar. Other exercises can be performed with this device as well. Typically for a novice, however, a pull-up or a chin-up can be difficult to do, thus requiring assistance. Additionally, for an experienced person, a pull-up or a chin-up can become relatively easy to do, thus requiring resistance. The present invention features a versatile doorway exercise system using a pull-up bar while adding assistance or resistance as desired.
The present invention features an exercise system using a standard sized door frame. In some embodiments, the system comprises a linear cylindrical bar with a bar first end perpendicularly located on a first jamb close to a first jamb anterior end and a bar second end perpendicularly located on a second jamb close to a second jamb anterior end. In some embodiments, the system comprises a linear first vertical post located on the first jamb below the cylindrical bar having a plurality of incrementally spaced first rings. In some embodiments, the system comprises a linear second vertical post located on the second jamb below the cylindrical bar having a plurality of incrementally spaced second rings. In some embodiments, the system comprises a padded resistance member having a plurality of first end elastic bands extending from a resistance member first end and a plurality of second end elastic bands extending from a resistance member second end. In some embodiments, each of the plurality of first end elastic bands comprises a first hook member, at least one of which is removably located on one of the plurality of first rings. In some embodiments, each of the plurality of second end elastic bands comprises a second hook member, at least one of which is removably located on one of the plurality of second rings.
Any feature or combination of features described herein are included within the scope of the present invention provided that the features included in any such combination are not mutually inconsistent as will be apparent from the context, this specification, and the knowledge of one of ordinary skill in the art. Additional advantages and aspects of the present invention are apparent in the following detailed description and claims.
