Ribbed wooden frames, horizontal bars and other leg presses. This type of exercise does not advocate that the elderly are pressing their legs hard or lifting their legs to a high pressure. High pressure does not mean health. The recommended maximum is not to shoulder.
The lower waist trainer should also be very careful, because there is less water in the muscles and soft tissues of the elderly, and some elderly people have osteoporosis, which will damage the lumbar spine.
(1) Lifting the leg too high when pressing the leg will threaten the femoral head and spine of the elderly.
(2) Try not to use the stretch trainer.
