On-Demand Supported Devices

While our site and player may work on older setups, we strongly recommend keeping your system as up to date as possible. Browsers and operating systems are constantly releasing bug fixes, security updates, and improvements, and it’s our responsibility to keep up with them as well. Using the latest browser version can always help to prevent unexpected problems with the MK Pilates pages and the general internet at large.

Below you’ll find our minimum requirements for streaming through MK Pilates.com, playback, and apps.

Supported browsers — playback

We support playback in browsers that can decode H.264 videos in an HTML5 player. 

Here is a list of our supported browsers/versions:

  • Chrome 30+ (has automatic updates)
  • Firefox 27+ (has automatic updates)*1
  • Internet Explorer 11*2
  • Microsoft Edge
  • Safari 9+

*1H.264 video (required for viewing MK Pilates videos) is only supported in Firefox for Windows 7 and later.

*2Older versions of Internet Explorer (IE 10, 9, 8, etc) that lack support for the TLS 1.2 protocol and HTML5 cannot be used to play our videos. As of January 12, 2016, Microsoft has stopped releasing updates to older versions of IE. (Microsoft's official statement on IE support can be found here - https://www.microsoft.com/en-us/windowsforbusiness/end-of-ie-support)

Supported operating systems — playback

The player operates in a wide range of operating systems, but we can only guarantee full functionality on systems that are still being supported by their proprietors.

Microsoft has ended support for Windows XP and Windows Vista.

The earliest version of MacOS still receiving extended support from Apple is Sierra (v. 10.12.6), and support for it is rumoured to end in September 2019. Earlier versions of MacOS (El Capitan, Yosemite, Mavericks, etc) are not supported.


  • Android (Lollipop) version 5.0+
  • iOS version 9.3.5+

* Blackberry and Windows phone users: You may still able to view our videos on devices that support HTML5; however, we do not test out our player in these environments and thus cannot guarantee support.

Internet Connection Requirements (playback)

We require minimum stable speeds of 1 Mbps or faster in order to view our lowest quality, SD 360p. Since bandwidth tends to fluctuate for a number of unforeseen variables, we always recommend you use a dedicated Internet line of 5 Mbps or faster to stream high quality videos on the Internet. For optimal performance, a hardwired connection via Ethernet is best, but if you prefer to use Wi-Fi, be sure that your router is configured correctly and that your network is not being shared with other devices (this can limit the starting speeds you pay your ISP for).

Not sure what speeds your device is receiving? Visit https://www.speedtest.net/ (on mobile or desktop) for an estimate. We recommend performing this test a few times since bandwidth can change.
