For coaches running high-intensity endurance training
Coach the whole class by real effort.
Heartstream gives coaches one live board to spot pacing, recovery, and overload across the room. You see who can push, who needs to reset, and when the session starts drifting off plan.
What trainers get
A clearer way to coach the room.
See the room live
One board shows who is below target, on target, or redlining.
Coach recovery with confidence
Know who is ready for the next round and who needs more time to come down.
Keep the session on plan
Adjust intensity before the class drifts into chaos or the strongest athletes burn too early.
Built for
High-intensity sessions where pacing matters.
Intervals
Keep work blocks honest
See who actually hit the effort target and who needs more from the next round.
Threshold
Control effort before fatigue wins
Keep threshold work under control before athletes go too hard too early.
Mixed groups
Coach different levels on one screen
Coach by effort when the room splits between athletes who are cruising and athletes who are close to the limit.

Big-screen class view

FAQ
Questions trainers ask first.
Who is Heartstream for?
Coaches running high-intensity endurance sessions, interval classes, and group training where pacing and recovery matter.
What changes during class?
Coaches can see who is under target, on target, or redlining and adjust the next cue before the session drifts off plan.
What does the setup look like in the gym?
Heartstream is built for a dedicated in-gym screen with a simple Raspberry Pi setup, so the coach has one live view on the floor.
Why use zones instead of BPM alone?
BPM shows the number. Zones make it easier to coach the next decision, whether that is pushing harder, holding pace, or recovering longer.
