For example, in the trial of Simple, novel physical activity maintains proximal femur bone mineral density, and improves muscle strength and balance in sedentary, postmenopausal Caucasian women by C M Young, B K Weeks, and B R Beck, published Oct. 18, 2017, the method used were, “Forty-five postmenopausal women not taking medications for bone health were randomly assigned to one of three groups. All groups attended one line dance class per week. Two groups additionally performed progressively loaded squats five times per week. One group also performed four foot stamps, twice daily, five times per week. Broadband ultrasound attenuation (BUA), proximal femur (PF) and lumbar spine (LS) bone mineral density (BMD), squats number, and balance variables were measured.” The results ended in “There were no differences within or between groups in baseline and follow-up BUA, PF or LS BMD; however, a strong stamp compliance effect was apparent for BUA (r=0.73) and PF BMD (r=0.79). Number of squats (p<0.01) and single leg stance time (p<0.01) increased, while timed up and go time decreased (p<0.01) for all participants.” They concluded that “Line dancing, particularly in concert with regular squats and foot stamping, is a simple and appealing strategy that may be employed to reduce lower extremity bone loss, and improve lower limb muscle strength and balance, in independent living, otherwise healthy, postmenopausal Caucasian women.”

Matthew Heur the inventor had an idea when he and his team were helping older people in the club, “Strong Teens Stronger Community” which allows teenagers to volunteer and help older people move heavy items around the house. During his volunteer time, he so that many older people suffered from a weaker body due to lack of exercise or osteoporosis. The elders needed a more fun and easier to use exercise machine for the lower body. Seeing this long-felt need, the inventor proceeded with the development of the following invention.

SUMMARY OF THE INVENTION

A bone density step trainer comprising a frame. The frame has a right upper frame member and a left upper frame member. The step trainer has a launcher formed as a lever. The lever is mounted on a lever pivot. The step trainer has a striker rail. The striker rail is vertically oriented and mounted to the frame. The frame includes a lower striker rail mount and an upper striker rail mount. The striker rail is mounted to a lower striker rail mount and an upper striker rail mount. A striker is slidingly mounted to the striker rail. The striker has a lower striker rail position and an upper striker rail position. The bone density step trainer optionally further includes a chime assembly mounted to the frame. The chime assembly has an upper chime and a lower chime. The upper chime is mounted above the lower chime and the striker is configured to hit the lower chime before hitting the upper chime.

The bone density step trainer may also have a resistance device that includes resistance members connecting between the launcher and a launcher base mounted below the launcher. The resistance device further includes a first resistance member, and a second resistance member. The first resistance member for connects to a first resistance band mount, and the second resistance member connects to a second resistance band mount. The first resistance band mount is formed on the launcher. The second resistance member is formed on the launcher. The first resistance member is connected to the launcher base. The second resistance member is connected to the launcher base. The first resistance member is removable, the second resistance member is also removable removing various resistance members decreases the resistance. The first resistance member and the second resistance member can be formed of elastomeric tubing.

The bone density step trainer has a third resistance member and a fourth resistance member. The third resistance member connects to a third resistance band mount. The fourth resistance member connects to a fourth resistance band mount. The third resistance band mount is formed on the launcher. The fourth resistance member is formed on the launcher. The third resistance member is connected to the launcher base. The fourth resistance member is connected to the launcher base. The third resistance member is removable, and the fourth resistance member is removable. The frame includes a front frame section, a right frame section, and a left frame section. The front frame section is connected to the right frame section and the left frame section. The right frame section forms a right handrail and the left frame section forms a left handrail. The front frame section includes the striker rail.
