強制1分間エクササイズ (Forced 1 Minute Exercise) is a Chrome add-on developed by Manten. As the name suggests, this program aims to prevent slacking off by automatically opening a fullscreen exercise website every hour at the 0-minute mark and prohibiting closing the browser for approximately 90 seconds.

By automatically opening the "強制1分間エクササイズ" website in fullscreen mode, users are reminded to take a break and engage in a 1-minute exercise routine. The program ensures that users cannot close the browser until they complete the exercise, effectively preventing them from skipping it.

One of the key features of this add-on is the ability to customize the time at which the exercise website opens. Users can set their preferred time interval, allowing for flexibility and integration with their daily schedule.
