Very cool.

Small critique: Wish the song transitions were smoother.

Regardless, I sat here watching it for 7 minutes, and I already feel healthier.

Very cool. However, no audio for folks outside U.S. (due to Rdio). Would be nice to have a small warning if this is this case, so users aren't left wondering if something is broken.

Yep, no audio in Europe! Just the first song! Would be great also just some sound to distinguish the start of one workout to the end of it

rdio works just fine in my part of Europe ;)

Rdio is available in Italy, but I can listen only the first song

Same here from Germany, I can listen to the first song just fine, and then it goes silent. I also miss a countdown tick sound (e.g., 7-min.com), which is very helpful for exercises on the floor.

It worked for me for the first exercise, I'm connected through Germany. After that it stopped.

Rdio is available in quite a few countries outside the U.S. http://www.rdio.com/availability/

Same issue in China.

Hi all, If you would be interested in the development of this, the source code of it: http://github.com/azer/7min.io

"Press any key to start" is a pretty useless instruction for tablet users without a keyboard.

Hi Luchs, you can also touch the screen; https://github.com/azer/7min.io/blob/master/lib/view.js#L28

Ah, this doesn't work on IE10 which doesn't implement the touch*-events. It would be nice if you enabled clicking (or added a listener for "MSPointerUp"[1]/"pointerUp"[2], which however would work for mouse as well).

could you send a PR to https://github.com/azer/7min.io ?

Sure, I'll create one tomorrow.

Related, I remembered IBM but turns out it was actually Compaq that had to explain in their FAQ what key the “Any” key was: http://web.archive.org/web/20070627063024/http://www29.compa...

and apparently at some point they changed the text to say “Press RETURN to continue”.

Arrow keys didn't work for me, so "Press most any key to start"?

I always start cautiously, with Ctrl.

Just pressing the screen worked for me

I'm on IE10, it probably only listens for WebKit touch events then.

Nice job...you just made me work out for 7 minutes :) That made my day.

"we have been having it!" - http://www.7-min.com/

Interesting. Looks like a more solid implementation. It includes more useful audio queues, and a "what's next" display.

Doesn't have the nifty music though, which seems to be the main point of the 7min.io implementation.

yeah, that app was my inspiration resource

I've been a long-time HN reader (i.e., lurker), but I've just become a commenter to say: Very cool. I'm sweating already. It also really commendable you've made it available open source. One small suggestion: Give a preview of the next work-out in the corner.

Nice, it should however display what the next exercise is during the rest timer countdown so you can get ready for it. For the ab crunches it takes a bit of time to get on the ground if you don't see it coming.

Interesting. I had no music till I enabled Flash. I could see this being useful if you get lots of different workouts, maybe a different one everyday? What happens if someone comes out with a 6 min workout :/

nice idea, but:

- Music is not everyones taste.

- Would be interesting to see an overview of the routine first.

> Would be interesting to see an overview of the routine first.

This refers to a specific workout which received a bit of attention in the news and here on HN in recent months :

Original discussion :

Thanks for the background.

This information should be easily accessible from the site.

Nice app. With respect to overview, it would be cool if you could click on the dots at the bottom to see the different sections.

I think that the latter could be addressed (for those familiar with the idea of the workout) by replacing the circles at the bottom with icons representing each workout. An interim hack might be to just crop the workout guy out of the images being used already, and shrinking that down to icon size.

Tried out the app. A few thoughts: - There's no way to tell what exercise is coming next, which breaks up flow. - The music changes sporadically, so you can't trust it to tell you when the exercise is going to change. This is confusing. - There is no audible signal that an exercise is starting or ending, so you have to watch the screen to check the countdown. - The circuit re-starts eventually, but there's no indication of how long the circuit has been running, and no way to stop it.

Suggestions: - Add an "on deck" icon, showing which exercise was going to come up next in the sequence. - Change the "rest" message to "rest and prepare for [next exercise]" - The app shouldn't require you to watch the screen, because this distracts from the exercise. Perhaps add audible queues counting down the end of each period. - Add a round / step counter. E.g. "Round 2 Stage 3" for the second time you reach the third exercise in the circuit

neat ideas! thanks!

If I press a key it just changes to a giant "3" and then a giant "NaN".

Very cool!!

Would be very amazing if the background image is a sea only during the rest

and a sound that alert you if time is over for that workout

Very nice. Can you please add a way to skip some workouts?

would be awesome if there is a choice to select a collection of music.

eg: feat Eminem feat Snoop dogg feat (any genre of music)

This is great. love the concept.

Very cool, I will use this.

Please add a mute button.

Good job Azer!

I don't get it.

absurdly loud

Pretty awesome

If I have a browser to use this website, I probably also have some application to play the music that I like.

yeah but how would you arrange your song plays corresponding to the exercise moods and times ?

Exercise moods? Times? I'm not sure I know what you're talking about.

The music I want to listen to while I'm exercising is pretty personal/subjective to me. I'm not the kind of guy to play Eye of The Tiger to "get pumped", or whatever. Or to think "hey those lunges have a real gangster rap mood to them".

have you given it a try ? :)

I have seen the first exercise, which gives me rap music. The other exercises didn't give me any music which was a relief, though there were not audio cues as to when the exercises began and ended. I didn't have much of a need to try to work out with it because I've already tried this: http://www.7-min.com/

ok, apparently Rdio doesn't play you the songs that I arranged...

if I have more chance to work on it, I'll build a menu to let people choose songs...

for now, you can just fork it; github.com/azer/7min.io

"Well, what happens if someone comes along with a 6 minute abs workout?"

Epic movie reference. :)
