Exemplary Uses of the Resistance Device
According to various embodiments, a resistance device, such as the resistance device 100 described above in relation to FIG. 1, can be used to improve the swing of a person playing a sport, such as baseball, softball, or golf. When swinging, the person typically stands such that one leg is a front leg and one leg is a back leg. If the person is swinging left handed, then the back leg is the left leg of the person, and if the person is swinging right handed, then the back leg is the right leg of the person.
The coiled portion 112 of the anchor 102 is screwed into the ground to secure the anchor 102 into a stationary position. The first fastener 108 is thread through the end loop 122 of the first tether segment 104 and secured adjacent an upper portion of the person's back leg, and the second fastener 110 is thread through the end loop 124 of the second tether segment 106 and secured adjacent a lower portion of the person's back leg. The person then moves (e.g., walks) in a direction away from the anchor 102 until the first and second tether segments 104, 106 are relatively taut and practice his or her swing. Alternatively, the anchor 102 can be placed at a distance away from the person such that it is taut before being secured in a stationary position. The device 100 prevents the person from raising his or her back leg during the swing motion. In other embodiments, the first fastener 108 may be secured adjacent the lower portion of the person's leg, and the second fastener 110 may be secured adjacent the upper portion of the person's leg.
The resistance device 100 may also be used to substantially prevent a person from raising at least one of the person's feet from the ground. For example, the resistance device 100 can be used to train a person to swing by maintaining his or her weight on a back foot, such as for sports such as baseball, softball, or golf. Alternatively, at least two resistance devices 100 can be used to train a person to ski by simulating downhill skiing, such as shown in the embodiment shown in FIG. 3. In particular, according to the embodiment shown, two resistance devices 100a, 100b are provided, and the anchors 102a, 102b, respectively, are screwed into the ground uphill from the person. The first fasteners 108a, 108b, respectively, are secured adjacent the upper portion of each leg of the person, and the second fasteners 110a, 110b, respectively, are secured adjacent the lower portion of each leg of the person. The person can then lean forward in the manner the person would lean downhill to ski with the resistance devices 100a, 100b holding the person in place on the hill.
