2.5 hours per week of exercise of any kind could help you live longer

That’s just half an hour daily, 5 times a week, there is really no excuse, except you are lazy and/or mentally ill, and anyone saying she or he has no time falls in one of those categories. I heard it all, no time, but playing GTA online on the weekend, no time but constantly posting on Instagram or Facebook and browsing aimlessly. Or bingewatching Game Of Thrones. Or some of the comments here which easily take you half an hour to compose. You have to set priorities, commit to that time and stick with it. I don’t say you can’t have some fun in your life, and believe me, working out is fun too, but AFTER you have done your duty of working out, for gods sake, skip even a meal for making time, it will be even healthier for you. Thats your health in the long run and should be the number one priority for you, for your own sake and for the sake of the people around you, think about the trouble and the worries you create for them living a sedentary life, if you don’t care about your own life, then at least be so decent and care about theirs. What helped me a very long time ago was to commmit to 15 minutes daily, no matter what. I used Jerry Seinfelds don’t brake the chain motivation technique, there are dozzen of apps which can help you with that. I had a streak of over two years before i took my first brake, now i work out 2.5 hours daily on average, and still waste a lot of time, and you guys will tell me that you won’t find that time even in one week? Come on! I hope nobody feels adressed by my posting, but i have the feeling there may be one or two guys, you know who you are;)

Someone told me the "Russian trick": every time you have a few minutes, just do some exercises: Squat, crunches, pushups.

It's not at all as good as a 15+min activity but by the end of the day it reinforces a lot of parts.
