Born as Web in June 2009 with the idea of helpful especially those bodybuilding fans who need a lot of information to learn and enter fully into this world of the weights. As its name suggests, this site is dedicated to providing all kinds of information from the world of bodybuilding so that visitors get the most complete information on many aspects of this sport, from national and international competitions, a typical exercises, through topics such as nutrition necessary or possible injury. Perhaps one of the things that may draw the attention of the visitor is the "Today we know a.." Which invites the aficionado, and the new visitor to dive into this world, knowing the lives of people who have gone far in the game with sacrifice and dedication. Furthermore, this site offers the possibility of dealing with the author to advise you on everything you need, adding a human factor and close to the web very important, because many people lost can be found in this area. Inspires and leads the thigh backwards to put the hip in hyperextension. Hold the contraction for two seconds and return to the starting position. It is an exercise that bodybuilders often do, but we've included because many women do you see in gyms. Can also be done at home in the apparatus multipower. Use low weight at first and hold on for balance. Use more weight than they can control, which forces us to use the inertia of our bodies to perform the exercise. This unit is in the gym, I still have not tried it because I believe that you can load the lower back, not the truth, I stay to the buttocks and sit with many strides je, je ..
The Sinclair ZX81 home computer is an 8-bit, designed and marketed by Sinclair Research in March 1981. The box was black with a membrane keyboard, the distinctive look of the machine was the work of industrial designer Rick Dickinson. The successor to the ZX80, the computer at a discount, based on a Zilog Z80A microprocessor clocked at 3.25 MHz [1] had 1K of RAM for programs and display. This was done in black and white (22 lines of 32 characters) on a SECAM TV, but without the keyboard with a slim and sensitive (membrane keyboard). The design of the ZX81 was designed to produce a computer performance modest, but at a reasonable cost. It passed first through a reduction in the number of components and optimizing their use. In this regard we can note two interesting features:. Firstly the presence of a dedicated integrated circuit, the ULA. Designed specifically for the ZX81, he replaced 18 standard TTL circuits of original ZX80. But the smartest is probably the technique used to control video that was provided by the microprocessor itself. Thus the frequency of 3.25 MHz were only justified to enable the Z80 to be compatible with the horizontal scanning frequency of televisions. The greater part of the CPU time was devoted to tracing the points arrays of characters on the screen. The code of user programs was discussed until the return line of CRT and during scanning blank areas at the top and bottom of the screen. A FAST nevertheless allowed to unload the microprocessor control video. The television screen is then covered with snow and programs, considerably accelerated, could not display anything. The programming was done in BASIC by typing the instructions were printed on the keys. BASIC offered the possibility to program in assembly indirectly through the PEEK and POKE commands. The machine was proposed in kit [2] to ride for 490 French francs in 1981. Many devices were available [3], including an extension of 16K memory, a thermal printer and a keyboard (like calculator) which is stuck on the original keyboard. Software, many games have been sold. (Flight Simulator, Cobalt Simulator, Mazzog) backups of programs and data were available on a cassette recorder. Its price (unbeatable at the time without the extensions), and especially his textbook, a teacher teaching the very concepts of programming in BASIC, made a great success, despite its poor performance, its BASIC incomplete resolution graphics grotesque and its lack of color. He was named the Offeror and permitted many future computer scientists to make their first steps at lower cost and without risk. There were several devices to buy if we wanted to either have color or sound, or an extended basic or enhanced graphics and more memory. These devices are connected behind the computer on a bus expansion. The memory upgrade was 16, 48 or 64 K. For color he had to disassemble the computer over a cable and solder the anode of diode D9 and close everything.The sound was in mono, the quality of a synthesizer. The Basic Extended offered many new keywords as many basic features that were new. The price of the ZX81 was certainly a great price (about 500 French francs), but when you add an extension that could cost around 600 to 800 French francs, the computer was expensive for what it gave in return. You will find in the chapters below details of the devices (sources manuals supplied with the devices). As mentioned above, this device claimed to play a screwdriver and soldering iron because it was a soldering device's cable into the anode of diode D9 of the computer, luckily a map printed circuit board with the connection was comes with the device. The cursor disappeared and devenaientt bands different colors each: the cursor becomes a green band F, K a white band, the G band The magenta and yellow stripe. We could play with a palette of 16 colors. The three channels had two registers a 8-bit and 4 bits. The soundtrack ranged from 24-101 563.50 periods. The volume ranged from 0-15 on each register. The stamp was one of the sounds for "dry" to 31 noises "deaf" (5 bits). The duration of the envelope was up 65,536 kinds of time. He brought new keywords that were bringing new features such as scrolling the screen up down left right. Graphic design of circles, squares, and text display of giants. Knowing the number of bytes in memory, use the sound card more easily, store encrypted data in programs to lowercase characters.
