The invention relates to renewable clean energy field, discloses a fitness exercise energy acquiring method and system, the method includes steps: (1) user signs up and sign in the system; (2) the system acquires fitness exercise energy and its users related information; (3) the system alters acquired energy into usable energy form; (4) the acquired energy is used; (5) user benefit from the system settlement; the system comprises components: (1) fitness exercise energy information acquiring subsystem; (2) fitness exercise energy information server and communication network system; (3) fitness exercise energy acquiring device; (4) fitness exercise energy usable electrical current alteration subsystem; (5) fitness exercise energy output control subsystem. The present invention realize change of energy released during daily fitness exercise into usable energy, both do fitness exercise and generate clean energy, fitness exercises of human and animals will generate more than one hundred millions kWh per day, with reference to present fitness equipment, obtain energy conservation and environmental protection timeliness of fitness exercises.

The present invention relates to wobbly balls and exercise coil springs. A wobbly ball may include a non-spherical rigid, hollow ball body formed of two halves, each half comprising an upper ladle or a lower ladle which are welded together along a central seam therebetween, and defining a hollow cavity therein. A spherical inner ball is captured within the hollow cavity of the hollow ball body of the wobbly ball, so that upon movement of the wobbly ball, the inner ball rolls within the cavity, producing a wobbly, eccentric motion. The exercise coil spring may be formed of a single coiled wire, the coiled spring including a central portion where the coiled wire is coiled to a first diameter that is constant. Opposed flared ends are provided ends of the central portion where the coiled wire is progressively coiled from the first diameter to a second diameter, which is greater.

Proposed is a portable self-power-generating apparatus which has small size and is capable of charging a battery by realizing self-power generation with high efficiency in emergencies in which normal electricity supply is not available, such as a military operation, a refugee village, a disaster caused by earthquake or the like, an emergency situation on ships, or an outdoor activity, and which can be used in combination with various smart modules.

A motor-less leg-powered curved treadmill produced that allows people to walk, jog, run, and sprint without making any adjustments to the treadmill other than shifting the user's center of gravity forward and backwards. A closed loop treadmill belt running between front and rear pulley rollers is formed with a low friction running surface of transverse aluminum, wooden, plastic, rubber or carbon fiber slats attached to each other in a resilient fashion. An essential feature of treadmill is the concave shape of the upper portion of the belt running surface, the treadmill configurations ensure that this shape is maintained during actual use. These configurations prevent the concave upper running surface portion from being pulled taut into a flat shape between the front and rear pulley rollers. The slats of the treadmill each have an end view crossectional I-beam shape, for strength and stability of the slat positioned upon the treadmill belt.

The present invention utilizes operation of a valve actuator to generate electrical power. A portion of the mechanical energy generated by operation of a valve actuator is converted to electrical energy. The mechanical energy may be converted to electrical energy at the same time as the valve actuator is operating or the mechanical energy may be stored for later conversion. A valve actuator may be operated manually, electrically, pneumatically, or hydraulically. Generated electrical energy may also be stored.
