<story><title>Show HN: My seven minute workout timer evening project</title><url>http://7-min.com/</url></story><parent_chain><item><author>danso</author><text>This is awesome. Just yesterday I was doing a 7-minute workout in my room, just because I was waiting for dinner to finish heating up.&lt;p&gt;The main problem is that the standard timer app on iOS only acts as a stopwatch...so the final ten seconds of each interval, I&apos;m watching the clock so that I can hit &quot;Lap&quot; and move on...this is awkward when I&apos;m also wearing headphones to listen to music.&lt;p&gt;What would be ideal for me is to have a simple timer that would alert me when the interval was done and automatically move on to the next one....like a repeating event on a calendar. I&apos;m sure there&apos;s an app for that but I just didn&apos;t feel like downloading a bunch and doing trial and error.&lt;p&gt;One more twist: I can&apos;t do all the exercises in the 7-min workout (as made famous in the NYT)...jumping jacks would annoy the shit out of the people below me. So I make up my own. A timer that would allow me to set up my own sequence would be fabulous.&lt;p&gt;Anyway, this is just a longwinded way of saying that there&apos;s a need for a niche app here, and it would definitely be a fun coding project...I&apos;m glad someone else thought of it first :)</text></item></parent_chain><comment><author>kinleyd</author><text>I&apos;ve read a bit about high intensity training (tabata, hiit, crossfit, etc.) and there seems to be quite a good bit of evidence supporting their utility. The 7-minute workout may well fit in that same category.&lt;p&gt;However, as an old fogie, I recall a craze back in the 70s and 80s called 5BX, which stood for 5 basic exercises, created by Swedish aircrew iirc. The reason I recalled it is the mention of rapid-style jumping jacks and push ups in the 7-minute workout. 5BX had increasingly quickened routines for jumping jacks (from a crouching position), sit-ups and push-ups (with claps thrown in as you completed each push-up).&lt;p&gt;All of this worked very well in terms of actually toning your body, getting a good daily cardio workout, and a sense of fitness... until it did irreparable back and other damage to quite a few people. So just be careful, especially if the high  intensity and the 7 minute time limit drives you to a regimen that gets anywhere close to a 5BX style work out in terms of quick, jerky movements.&lt;p&gt;Personally, I&apos;ve reverted to playing basketball like I did in my college days, with high intensity worked into it with repeated lay up, jump shot routines, etc. It&apos;s working great for cardio and overall body toning. I would like to do weights as well, as there is a body of evidence pointing to its value, but basketball is plenty far for me at this stage.</text></comment>
