The Ultimate Plan for How to Lose Belly Fat

Apr 12,  · At age 14, you may want to get a "six-pack" to look more like the models you see on TV or to improve the way your body looks at a pool party. Having strong abdominal muscles can improve your athletic performance and reduce your risk of injuries — although, you don't need six-pack abs . The absolutely “fastest” way to get in shape is to, of course, do everything right. But since I’m assuming that we’re all human, it’s almost impossible to do EVERYTHING right for any extended duration. Yes, some fitness professionals or athletes or certain actors and models can get close to “perfection” for a specific amount of time.

Over the years, I have been asked this question in many fawtest ways. But for most of us, we need to accept that sometimes we may need to miss a workout or two.

There are many aspects of a fitness lifestyle, but there are four main components which I have learned are the most crucial:. These are all common questions. You can hit me up with hoow questions on social media, either on InstagramFacebookor Twitter. He played professional soccer for seven seasons after graduating from Northwestern University.

Andy has published more than articles and videos how to score in gate national media publications. Andy posts fitness challenges on InstagramFacebookand Twitter. HIs latest can be found here. David Baye explains how this classic lift can help anyone achieve thf size and strength. Courtesy of Andy McDermott. We must so some type of physical movement every day. By tye, the most important aspect of this component is consistency.

Much more to discuss here in future articles. In order to create positive change, intake what we eat and drink -—especially as our bodies mature—is considerably more important than the type of exercise we do.

Stay tuned for more on this. So why do so many of us work avs hard to destroy any chance that we get how to get abs the fastest way sleep? Until next time, take care of yourselves, and be good to each other.

Apr 09,  · The best way to lose belly fat is and to shrink fat cells overall is to lose weight. But make no mistake: belly fat is not easy to get rid of. Start by figuring out your current daily calorie intake. Then cut that number by one quarter. Feb 22,  · Men with six-pack abs usually have a body fat of between 6 and 9 percent and women between 16 and 19 percent. The same body fat percentages apply to the idea of a teen six pack, too. To get to such lean levels, lose excess body fat through proper diet and exercise.

Nevertheless, it works at least for me for some input numbers:. Warning: timeit results may vary due to differences in hardware or version of Python. Personally I think it is a shame that numpy which is so widely used is not part of Python standard library, and that the improvements in syntax and speed seem to be completely overlooked by Python developers. There's a pretty neat sample from the Python Cookbook here -- the fastest version proposed on that URL is:.

You assume that numbers. Sets are unordered and pop removes and returns an arbitrary element, so it cannot be used to select the next prime from the remaining numbers. For truly fastest solution with sufficiently large N would be to download a pre-calculated list of primes , store it as a tuple and do something like:.

If you don't want to reinvent the wheel, you can install the symbolic maths library sympy yes it's Python 3 compatible. And use the primerange function. The only substantial change is using a bytearray instead of a list for the boolean, and using compress instead of a list comprehension to build the final list.

I'd add this as a comment like moarningsun if I were able. It's instructive to write your own prime finding code, but it's also useful to have a fast reliable library at hand.

If you have control over N, the very fastest way to list all primes is to precompute them. Precomputing is a way overlooked optimization. For the fastest code, the numpy solution is the best. Since I make the entire list in memory, you need enough space to hold everything, but it seems to scale fairly well. Can someone compare this with the other timings? On my machine it seems pretty comparable to the other Numpy half-sieve. I tested some unutbu's functions , i computed it with hungred millions number.

Complete code on my github repository. I've updated much of the code for Python 3 and threw it at perfplot a project of mine to see which is actually fastest.

First time using python, so some of the methods I use in this might seem a bit cumbersome. Nonetheless this is my suggestion for a pure python prime sieve, based on omitting the multiples of 2, 3 and 5 by using appropriate steps while processing the sieve forward. By using a ctypes. Here is an interesting technique to generate prime numbers yet not the most efficient using python's list comprehensions:. You can find the example and some explanations right here.

Here is a numpy version of Sieve of Eratosthenes having both good complexity lower than sorting an array of length n and vectorization. Compared to unutbu times this just as fast as the packages with 46 microsecons to find all primes below a million. So why not just write a slow script that generates another source file that has all numbers hardwired in it, and then import that source file when you run your actual program.

Of course, this works only if you know the upper bound of N at compile time, but thus is the case for almost all project Euler problems. PS: I might be wrong though iff parsing the source with hard-wired primes is slower than computing them in the first place, but as far I know Python runs from compiled. While searching for the next composite, we need to test odd numbers only. While we're at it: instead of the elegant 'D. At least on my machine PGhz. So I suggest this implementation of this clever algorithm:.

The fastest method I've tried so far is based on the Python cookbook erat2 function:. See this answer for an explanation of the speeding-up. I may be late to the party but will have to add my own code for this. How are we doing? Please help us improve Stack Overflow. Take our short survey.

But can't beat sundaram3. Thanks for the question. It'd be nice if there could be Python 3 versions of the functions in the answers. Isn't there anything like require 'prime'; Prime. ColonelPanic As it so happens I updated github. ColonelPanic: I think editing old answers to note that they've aged is appropriate, since that makes it a more useful resource.

If the "accepted" answer is no longer the best one, maybe edit a note into the question with a update to point people at the current best method.

If you're using pypy, these benchmarks the psyco ones seem fairly off. This is what I found for the non-numpy ones gist. If someone wonders how the functions here fare against PG7. Can you update this with PyPy, now that psyco is dead and PyPy has superseded it? Would be great if these functions and timings could be updated for python3.

Show 25 more comments. Numpy is now compatible with Python 3. The fact that it's not in the standard library is good, that way they can have their own release cycle. When casting in the primesfrom2to method, should the division be inside of the brackets? For a pure python version compatible with python 3, follow this link : stackoverflow.

And it can be made even faster with a minor change: see stackoverflow. Test it here. Add a comment. Not the prettiest code in the world, but a bit faster : — truppo Jan 20 '10 at I just realized that passing None instead of the original function works and it's even faster than zero.

Did you know that if you pass sundaram3 9 it will return [2, 3, 5, 7, 9]? It seems to do this with numerous -- perhaps all -- odd numbers even when they aren't prime — wrhall Sep 21 '13 at Always think outside the box. Kimvais Kimvais 34k 14 14 gold badges 99 99 silver badges bronze badges. To be fair, though, you'd have to count the time downloading, unzipping, and formatting the primes and compare that with the time to generate primes using an algorithm - any one of these algorithms could easily write the results to a file for later use.

I think in that case, given enough memory to actually calculate all primes less than ,,, the numpy solution would still be faster. Daniel correct. However the store what you have and continue whenever needed still stands Daniel G I think download time is irrelevant.

Isn't it really about generating the numbers, so you would want to take into account the algorithm used to create that list you're downloading. And any time complexity would ignore the once of file transfer given it O n. The FAQ for the UTM prime page suggests calculating small primes is faster than reading them off a disk the question is what small means.
