Article: An alkyne is a hydrocarbon chain that contains one or more triple bonds between carbons. The suffix at the end of an alkyne should always be -yne. The parent chain of an alkyne must contain any carbons that are triple-bonded. Number it from the end nearest to a triple-bonded carbon. If you're dealing with a molecule that has both double and triple bonds, start the numbering from the end located closest to any multiple bond. In addition to noting where substituents are on an alkyne chain, you must also note where the triple bond is. Do this such that the lowest number on the triple bond is used. If your molecule contains double bonds as well as triple bonds, you must locate these as well. If your parent chain has two triple bonds, the name will end in "-diyne." Three is "-triyne," and so on. As with alkanes and alkenes, you must list substituents alphabetically in the final name. Exclude prefixes such as di-, tri- and delta-. If your molecule contains double bonds as well as triple bonds, the double bonds must be named first.
Question: What is a summary of what this article is about?
Learn what an alkyne is. Draw out the molecule. Locate the parent chain. Note where the triple bond is located. Modify the suffix based on the number of triple bonds in the parent chain. Name the substituents alphabetically.

Many people favor one leg more than the other and it will be easier if you use the favored leg at first. To find out which leg you favor, place one foot in front of you and the other behind and stand for a few moments, then swap over and do the same. The leg you had in front when you felt the most comfortable is your favored leg. Place the other leg behind. Stand up with your hips square. If using pillows, place the pillows between your legs, where your hips will be. Slide down. Slide the front foot forwards and the back one backward. Aim to go as far as you can without forcing the movement, making sure that you have a support to hold onto so that you don't go too far. When you start to feel the pull of your muscles, hold it there for 10 to 15 seconds. Hold your position by supporting yourself with your hands. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/7\/77\/Do-The-Box-%28Front%29-Splits-Step-7.jpg\/v4-460px-Do-The-Box-%28Front%29-Splits-Step-7.jpg","bigUrl":"\/images\/thumb\/7\/77\/Do-The-Box-%28Front%29-Splits-Step-7.jpg\/aid158471-v4-728px-Do-The-Box-%28Front%29-Splits-Step-7.jpg","smallWidth":460,"smallHeight":205,"bigWidth":"728","bigHeight":"324","licensing":"<div class="mw-parser-output"><p>License: <a rel="nofollow" class="external text" href="https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/">Creative Commons<\/a><br>

Use your mind to relax your muscles instead of forcing them. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/4\/47\/Do-The-Box-%28Front%29-Splits-Step-9.jpg\/v4-460px-Do-The-Box-%28Front%29-Splits-Step-9.jpg","bigUrl":"\/images\/thumb\/4\/47\/Do-The-Box-%28Front%29-Splits-Step-9.jpg\/aid158471-v4-728px-Do-The-Box-%28Front%29-Splits-Step-9.jpg","smallWidth":460,"smallHeight":195,"bigWidth":"728","bigHeight":"308","licensing":"<div class="mw-parser-output"><p>License: <a rel="nofollow" class="external text" href="https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/">Creative Commons<\/a><br>

Do it at your own pace. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/d\/d9\/Do-The-Box-%28Front%29-Splits-Step-10.jpg\/v4-460px-Do-The-Box-%28Front%29-Splits-Step-10.jpg","bigUrl":"\/images\/thumb\/d\/d9\/Do-The-Box-%28Front%29-Splits-Step-10.jpg\/aid158471-v4-728px-Do-The-Box-%28Front%29-Splits-Step-10.jpg","smallWidth":460,"smallHeight":178,"bigWidth":"728","bigHeight":"282","licensing":"<div class="mw-parser-output"><p>License: <a rel="nofollow" class="external text" href="https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/">Creative Commons<\/a><br>

<\/p><\/div>"} Once you've held the position there a few times, it's time to go a little bit further. Ease yourself down by a centimeter (1/2 an inch) at the absolute maximum, if you feel ready. Pushing more than that at one time will hurt and could cause damage to your muscles, so once you're down another centimeter, hold your position, as long as it doesn't hurt too much. Hold that for about 5 seconds. Then repeat the process of slowly working your way down to the ground.

One-sentence summary --
Decide which leg is naturally easier for you to use. Place your favored leg in front of you. From a standing straddle position, slowly make your way towards the floor. Find a position where you feel a little stretch, but the rest of your body weight is supported on the pillows (if using). Go further when ready. Relax and stretch out your muscles a bit.
