    Hey HN,

    We've built www.co-train.space to stay fit while staying home. You pick fitness video on Youtube, it plays synchronously for everybody in the group and you see your peers thanks to Jitsi Meet (Zoom-like software).

    I am now exercising with my parents every morning and feel much more connected to them. Looking forward to hearing what you think!

    Feature idea: use the webcam to project the watcher's image/body onto the instructor's. Then with some computer vision magic, gamify how close your workout matched the instructor's workout.

    Does this handle ad breaks? I think with a monetized video different people may get different length ads at different places. Just curious how this would handle that situation.

    What kind of issues did you have syncing with youtube videos and what kind of latency do you experience?

    BTW Great initiative and certainly could use that tech for many avenues like remote classroom, any presentation with Q&A. Few others I suspect, but great start.

    I bought a projector just to make my fitness videos life size on the wall. It sounds lame but it has helped my mental health.

    Adding the video conference element is a really great idea. Now I just have to find the best place to mount a webcam.

    Nice. Most of the instructors on our system* have pivoted to run their classes online like that now too. YouTube or Vimeo synchronized with a live Zoom.

    It's actually working really well for them as they can now open to a wider audience! It's great to see how people have adapted so quickly in the lockdown.

    It’s always so exciting when you have an idea, and then get out of having to make it cause it was posted here first, love that about hn. Great job!

    Really neat idea - I'm a fan anything that helps people improve their health habits whether individually or collectively!

    Great work, this is exactly what my wife has been doing via Zoom and Youtube with her gym class.

    They had been watching the live feed each morning alone and found a lack of motivation since they were used to working out together.

    So there is a market for sure

    This is pretty fantastic, not just for working out. Kudos!

    This is great! I would love to see a version where you can Sync Spotify playlists & have the fitness instructor teach live

    I want this but just for watching general youtube videos sync'd with people

    This is great. The UX is awesome. Do you have limits on number of users here?

    Great idea! Tried it with mum, worked quite well!
  • by frequentnapper on 4/16/20, 11:14 PM

    does this allow anybody in the group to pause/move anywhere in synchrony
