❤️Heart Rate ZONES
Dial in your training intensities. Calculate your exact physiological zones using the proprietary RESILIENTO LTHR model.
Heart Rate Profile
How to find your LTHR: Modern fitness watches (Garmin, Coros, Apple Watch) often estimate this automatically after hard runs.
Field Test: Run a 30-minute all-out time trial by yourself. Your LTHR is your average heart rate for the last 20 minutes of the effort. (Alternatively, take 95% of the average HR from a 20-minute all-out test).
Calculated Training Zones
RESILIENTO (LTHR)Why LTHR?
Heart rate zones are critical for ensuring you are targeting the correct energy systems during training. If you ride or run purely by feel, you risk making your easy days too hard, and your hard days too easy.
Anchored to Physiology, not Maximums
Lactate Threshold Heart Rate (LTHR) is the average heart rate you can sustain for a 60-minute all-out race effort. Because it anchors your zones to your actual metabolic threshold rather than an arbitrary maximum, it is universally considered the most accurate method for endurance athletes. The RESILIENTO framework uses a precision 5-zone LTHR system mapped directly to our hybrid training plans.
Standardized Intensity
Unlike standard % Max HR formulas that guess your limits based on age, LTHR is completely individualized. Two athletes with identical Max HRs can have wildly different Lactate Thresholds, making generic zones dangerous for structured training. By testing and setting your LTHR, every workout specifically targets the intended adaptation.
Training zones are only as good as the plan that uses them.
Knowing your LTHR is the first step. The RESILIENTO engine automatically structures your entire week of endurance and strength around these exact physiological zones to guarantee progress without overtraining.
