Readiness
HRV, resting heart rate, and sleep read against your own baseline — not a generic target.

Training that reads your recovery
Havik measures the load, readiness, and performance behind every session — then adjusts your plan from what actually happened, not what was scheduled.

Training insights
What Havik measures
Every session you log feeds a set of models that describe your training — long before any of it reaches a conversation.
Training load
Acute against chronic workload, so a spike shows up as a number before it shows up as an injury.
Muscle balance
Ten days of volume across every muscle group, decayed and mapped onto your body.
Strength level
Bodyweight-relative standards on the main lifts. Know where you actually stand, lift by lift.
Endurance level
A VO₂max-equivalent score set against age- and sex-adjusted norms.
Thresholds
FTP on the bike, CSS in the pool, pace and heart-rate zones on the run — all computed from your sessions.
Built on established models — EWMA acute:chronic workload, Daniels–Gilbert VDOT, and bodyweight-ratio strength standards.

Readiness & load
Know what your training is doing to you
Havik reads heart-rate variability, resting heart rate, and sleep against your personal baseline, then sets that beside your acute-to-chronic workload. You see strain building while it is still a number on a screen — and you see the weeks where you have room to push.
Plans
A plan built around your sports, your equipment, your week
Follow detailed strength and endurance prescriptions with a complete training calendar. Every block carries real structure — progression waves, thresholds, and recovery — not a list of workouts to check off.

Next week isn’t decided until this week is done
Havik marks upcoming weeks as provisional. When the block before them completes, it reviews your recovery, effort, and performance — then advances, holds, or backs off the progression. No manual deload guessing, and nothing you have to ask for.
Log
Log it once. It shows up in six places.
Sets, reps, load, RPE, pace, heart rate, distance, stroke, and power. Every entry updates your e1RM trends, muscle load map, weekly load balance, and threshold estimates — so logging is the work, and the analysis is free.

Chat with Coach
A coach that already has your numbers
Ask why a session felt hard and it can see your readiness, recent load, and the heart-rate data for that exact workout. The conversation starts with context instead of a questionnaire — and it can rebuild the plan when your life changes.
