PLANK STAND

FIELD OF THE INVENTION

The present invention generally relates to the field of exercise and specifically to an exercise “plank stand” enabling to strengthen abdominal/back, leg, and other muscles while standing or sitting.

BACKGROUND

A wide variety of exercise apparatuses have been developed to specifically exercise the abdominal/back muscles of a user. The apparatuses generally require that the user change into appropriate sports attire, go to the gym or concentrate on exercising, adjust a rather cumbersome device, sit upon the device and secure any straps that may be required in order to use the device, before proceeding with a desired exercise routine. Many such devices do not enable the user to comfortably engage in other activities while exercising, such as, for example, working, meeting with another person and the like.

A familiar exercise has become what is known as the “plank”, where a person rests his or her entire weight on their toes at one end and on their elbows or forearms at the other. The objective is to maintain the body in a horizontal stationary position. The stress is considerable, and a person may be able to maintain this position for a duration of anything between several seconds to a few minutes.

Therefore, there is a need for an easy and safe to use plank stand enabling the user to engage in a mainly static exercise for long durations, with low stress and effort levels while, at the same time, for the user being able to partake in other activities, such as, typing, texting, reading, watching TV, conversing etc.

The above mentioned plank exercise (and conventional exercise devices that may simulate the plank position) has the weight of the exerciser supported at both ends of the body, i.e. feet and arms (or chest). The plank stand, in contrast, supports the user only at one end of the body - below the knee (and in a more moderate position, below the pelvis), with the user in a cantilever plank position. The advantage of this approach is that even a slight angle of inclination can create a significant physical effect.
