For years the idea that low intensity, long duration, single mode, so called ‘fat burning’ models of exercise have existed which we now know do not give us the true health and fat loss results that we expect.

We have previously been mainly focused on simply ‘burning off’ calories while we are exercising yet we really need to be performing the type of exercise that tells our body to grow, to build new metabolically active tissue that has us running at a higher metabolic rate all day and all night long.

This means we can ‘teach’ our body to be a more efficient fat burning machine as we now have the knowledge and understanding or how exercise impacts on our hormones and metabolism. But for this to be truly effect the exercise that we do has to be intense enough cause mechanical and metabolic muscle failure to stimulate the hormones that cause a ripple affect that lasts long after the exercise session has ended.

Long duration activities do not do this and when we stop doing them our metabolic rate goes back to our old slowed level and does not burn as much fuel as it could be if we changed our exercise regime.

Proper strength training exercise that directly targets the muscles offers exactly what we need to boost our metabolism for maximum health benefits or fat loss. Strength training offers short duration, high intensity exercise that can give us as much as three times the results in half the time of old fashioned low intensity activities.

You are really training for the metabolic effect that offers a real body transformation and strength training is perfect for people frustrated by cook-book exercise prescriptions that are so ineffective and time consuming. This knowledge is going to be of great help to gyms and healthcare providers in the future to combat the massive growing epidemic of overweight people that now number two thirds of the population.

Strength training exercise is so effective in making the changes to the metabolism right down at cellular level where it really matters only a little is needed. Just 2-3 sessions each week done with enough intensity (degree of effort) used will give a huge boost to the metabolism.

Imagine just boosting the rate your body burns fuel by as little as 5 percent and it is possible to increase the ‘burn’ up to 15 percent. This is where you will get long-term fat loss from as your body chews up that stored energy for fuel for the muscles to use.

If you are not already get yourself started on a strength training program and use it as your number one exercise regime doing it first and foremost each week. You will be delighted when you finally start to see visible and measurable results. Give it some time and slowly you will have your slim trim body returned to you for good.

Steering the beam

Of the available marking technologies, beam-steered laser marking systems provide users with the greatest amount of image flexibility in a fast, permanent, noncontact marking process. As manufacturing processes become more automated and after-sale tracking more prevalent, laser markers are frequently the only method available to produce individually unique, permanent images at high speed.

Beam-steered laser marking systems usually incorporate either a CO2 or Nd:YAG laser. The CO2 laser emits a continuous-wave output in the far-infrared (10.6-um wavelength) while the Nd:YAG laser emits in the near-infrared (1.06 um) in either a CW or pulsed mode (1 to 50 kHz). The Nd:YAG laser is also unique in its ability to produce very short, high-peak-power pulses when operated in the pulsed mode. For example, a typical 60-W-average-power Nd:YAG laser can produce peak powers on the order of 90 kW at 1-kHz pulse rate.

The delivery optics consist of either a simple focusing lens assembly or a combination fixed upcollimator and flat-field lens assembly. In either instance, the laser beam is directed across the work surface by mirrors mounted on two high-speed, computer-controlled galvanometers.

The simple focusing assembly offers the advantages of low cost and fewer optical components and is routinely used with CO2 lasers. The flat field lens design, though more expensive, maintains the focal point of the marking beam on a flat plane for more consistent image characteristics throughout the marking field. The flat-field lens also produces higher power density on the work surface than the simple focusing assembly due to the shorter effective focal length. The flat-field lens design is always preferred for high-accuracy and high-image-quality applications and is usually incorporated with Nd:YAG lasers.

Both designs provide the user with a selection of lenses that establish both the diameter of the marking field and the marking-line width. Longer-focal-length lenses provide larger working areas, but the line width is also enlarged, thus reducing the power density on the work surface. The user must compensate by either increasing the laser output power and/or decreasing the marking speed which usually consists of two lenses and may be placed anywhere in the beam path before the focusing lens. A beam expander often is used instead of extending the beam path approximately 10 more feet, in which the beam expands through its inherent tendency to diverge as it exits the resonator cavity. A spatial filter inserted within the beam expander produces the best mode quality in close-coupled systems, by passing the beam through a small aperture.

The last optical element that a laser beam encounters is the focusing lens. With CO2 lasers, this lens is usually made from one of several materials: Zinc selenide (ZnSe), gallium arsenide (GaAs) or germanium (Ge). ZnSe, a dense, yellow material that is transparent to visible wavelengths, is by far the most common of these materials, and it allows a low-power, HeNe laser beam through for alignment purposes. This is a great advantage over GaAs or Ge which are opaque to light from the visible portion of the spectrum.
