Lock In Performance, Not Potential
In the heat, performance loss isn't a risk—it's a guarantee.
The Facts: Real Performance Loss
The science is clear. Your body fights to stay within a narrow range around 98.6°F — and when it can't keep up, you start to break down before you even feel it.
- At 102.2°F core temperature, reaction times slow by 10-15%.
- Every 1.8°F rise in core temperature drops endurance 2-3%.
- At just 2% dehydration, work capacity falls by 30%.
Once your athlete's core body temperature crosses these thresholds, that capacity is gone—they can't push through it, and they can't get it back that session.
They won't feel it until it's too late. You won't see it from the sideline. The loss happens long before any symptoms show.
Eliminate the Guesswork. Maximize Greatness
Every athlete has a zone—an optimal range where their body performs at full capacity. Heat quietly pushes them out of that zone. Most athletes never find their edge because they blow past it without knowing.
HeatSense shows where the zone is. Train right up to the edge. Know when to push, when to cool, when to recover. Stop leaving performance on the field because no one could see it slipping away.

Why Not Invest in a Sure Thing?
You've already spent thousands—club fees, travel ball, private coaching, premium gear. All of it is potential. A bet that your athlete will step up and deliver.
HeatSense isn't a bet. It shows you exactly what's happening inside your athlete's body—every practice, every time. Guaranteed visibility. A sure return on what you're already investing.

Frequently Asked Questions
A lightweight sensor worn on a chest strap or armband. It's comfortable, non-invasive, and designed for high-intensity training. Most athletes forget it's there after a few minutes.
The HeatSense app connects via Bluetooth and shows real-time data on your phone—core temperature, skin temperature, heart rate, plus environmental conditions. You get alerts when they're leaving their optimal zone.
Know when to cool off and hydrate, when to rest, when to push. If you see core temp climbing toward the edge of their zone, you can intervene—water break, shade, dial back intensity—before capacity is lost. It's actionable insight, not just numbers.
Not required. Many parents start using HeatSense individually—you'll have visibility even if the coach doesn't. That said, we also offer a Team Dashboard for programs that want roster-wide monitoring.
