Abstract: An elastically modifiable wallet is an apparatus that is able to hold and organize a user's financial or personal items in accordance to how frequently the user accesses each financial or personal item. The apparatus includes a tubular band, a tubular strap, a tubular strip, a finger loop, a first stitch, and a second stitch. The tubular band, the tubular strap, the tubular strip, and the finger loop are each made of elastic fabric. The tubular band is used to hold weekly/occasionally used items, such as business cards. The tubular strap is used to hold daily used items, such as a regular credit card. The tubular strip is used to hold frequently used items, such as loose cash. The finger loop allows a user to easily grasp and disengage the tubular strip. The first stitch and the second stitch are used to hold these pieces of elastic fabric together.
Abstract: A muscle training method includes the following steps that are repeated alternately to perform training of a muscle of a user: a pressuring and exercise step (S30, S50, S70, S90) of winding a belt around at least one of four limbs of the user and applying specific pressure thereto so as to restrict blood circulation of the muscle of the user without stopping the blood circulation, and asking the user to perform load-applied exercise to apply load of specific weight to the muscle of the user; and an exercise stopping step (S40, S60, S80, S100) of asking the user to stop the load-applied exercise while continuously applying the specific pressure to the user. The specific weight is set at a value smaller than maximum weight necessary for the user to exert maximum muscle force.
