Live & On-Demand Video Coaching

The energy of a live class and the flexibility of on-demand, delivered without buffering or lag

Live video coaching streams a real-time class with low enough latency for a trainer to see and respond to participants, while on-demand video lets users work out on their own schedule from a recorded library. Both need to handle unpredictable traffic — everyone showing up at the exact top of the hour for a popular live class — without buffering or crashing.
The two modes have genuinely different engineering demands. Live coaching needs low-latency streaming infrastructure and can spike to enormous concurrent viewership in the exact same few minutes as a class starts, which is a traffic pattern that breaks naively-built systems. On-demand needs efficient video encoding and adaptive bitrate streaming so a workout plays smoothly whether someone’s on home wifi or a spotty gym connection — different problems requiring different infrastructure choices, even though they share a video player on the surface.

Implementation

How We Actually Build This

1

Live classes stream through a low-latency streaming protocol (WebRTC or LL-HLS) capable of handling large simultaneous concurrent viewership spikes at class start time

2

On-demand video uses adaptive bitrate encoding, automatically adjusting quality to the viewer’s connection speed without manual selection or buffering interruptions

3

A CDN distributes both live and on-demand video globally, so viewers stream from a nearby edge location rather than a single origin server

4

Interactive features (live chat, trainer shoutouts, real-time leaderboards) sync tightly with the video stream’s actual timing, not an approximation

Key Benefits

Frequently Asked Questions

Common Questions About Live & On-Demand Video Coaching

Why is live class traffic harder to handle than on-demand video?+

Live classes concentrate enormous concurrent demand into the exact same few minutes as the class start time, whereas on-demand traffic spreads naturally across whenever individual users choose to watch — that concentration is what requires infrastructure specifically built to absorb sudden spikes.

How much latency is acceptable for a live fitness class?+

Low enough that a trainer’s real-time cues and participant reactions still feel synchronized — typically under a few seconds is the target, since noticeably higher latency breaks the sense of a shared, live experience.

Does on-demand video need to be re-encoded for every device type?+

Adaptive bitrate encoding produces multiple quality versions of the same video once at upload time, and the player automatically selects the right version per device and connection speed — not a separate re-encode per device.
