the relationship between them is that the machines have friction that makes the machine goes
There are no specific pieces of exercise equipment for reducing belly fat. You will have to consume less calories and exercise in order to lose fat. Equipment that burns the most calories will aid in this. Cardio workouts are useful for helping with this.
A machine makes work easier by reducing force and increasing distance.
Bearings help machines work smoothly and keep gears and machines that need bushings (with bearings in them) from wearing out too quickly. Bearings significantly reduce friction in working machines (with the help of a bit of oil and grease), thus reducing wear and tear--and reducing maintenance costs and times of repair.
It can help by reducing your carbon footprint
The hip reducing machine was a long sturdy belt attached to a motor on a pole at hip height which vibrated. The theory was that you shook the fat and it was exercise. Spot reducing was very popular at the time, and these machines were also available in a home model. My grandmother had one, and it was fun to stand on it and shake.See the link for the picture of a belt machine. It's the second image on the site.Another one that was popular was a roller contraption that you "sat" on. There were hand holds and the wooden knobby things beat your butt on the theory that the "exercise" would reduce the fat in your rear.
The diode laser module is more effective at reducing power consumption in machines because it has the lowest possible pump photon energy. It is made by pumping a solid gain medium such as a ruby.
Exercise combined with reducing the intake of food helps you to loose weight by burning calories that are consumed. Exercise increases the metabolism and make it so that the body burns more calories than are taken in by food.
Not many. Regular resistance exercise and aerobic exercise can actually help to increase bone density, reducing the risk of fractures. As with any program of exercise, consult a physician before beginning.
