HRV for CrossFit

Use HRV to train smarter in CrossFit. Know when to go Rx vs scale, avoid overtraining, and optimize recovery between high-intensity WODs.

CrossFit's Unique Recovery Demands

CrossFit training creates distinct HRV challenges:

Mixed modalities: - Combines weightlifting, gymnastics, and cardio - Each stresses different systems - Total load accumulates from multiple directions

High intensity frequency: - Many CrossFitters train hard 5-6 days/week - Limited built-in recovery - Easy to accumulate fatigue without realizing

Competition elements: - WODs push you to go all-out - Hard to self-regulate intensity - HRV provides objective feedback

Daily Training Decisions

High HRV day: - Go for the Rx weights - Hit the metcon hard - Good day for heavy lifts or skill work

Low HRV day: - Scale weights appropriately - Focus on technique over intensity - Consider active recovery instead - Or train but accept lower output

Very low HRV: - Strong signal to rest or do light mobility - Pushing through risks injury and overtraining - One rest day prevents many forced rest days

The CrossFit culture encourages always going hard. HRV helps you go hard when it counts and recover when needed.

Programming Considerations

Following a gym's programming: - You can't control what's programmed - Use HRV to decide HOW to approach the workout - Low HRV = scale, moderate, or skip

Designing your own programming: - Include built-in recovery days - Vary intensity across the week - Watch HRV trends to validate your approach

Common intensity mistakes: - Every WOD at 100% effort - Heavy lifting 4+ days per week - No true easy/recovery days - HRV reveals these mistakes quickly

Strength Training Component

Heavy lifting significantly impacts HRV:

After max-effort lifting: - Expect HRV suppression for 24-48 hours - CNS fatigue doesn't always feel obvious - Plan lighter days after heavy days

Olympic lifts: - High skill demand compounds stress - Heavy snatch/clean & jerk days = recovery needed - Technical breakdown when fatigued = injury risk

Recommended approach: - Check HRV before heavy lifting sessions - Low HRV + heavy day = reduce weight or volume - Save PRs for high HRV days

Competition Prep

Leading up to competition: - Reduce volume 1-2 weeks out - HRV should rise as you taper - If HRV stays low, extend your taper

Competition day: - Some pre-competition HRV dip is normal (nerves) - Don't obsess over the number - Trust your preparation

Multi-day competitions (CrossFit Games style): - HRV will drop across the weekend - Focus on recovery between events - Sleep, nutrition, and light mobility

Post-competition: - Expect suppressed HRV for days to a week - Don't rush back to hard training - Light movement and full rest

Avoiding Overtraining

CrossFit athletes are at high risk for overtraining:

Warning signs in HRV data: - Chronically suppressed baseline (weeks, not days) - HRV doesn't recover even with rest days - Resting heart rate trending up - Performance declining despite hard training

Prevention: - Include at least 1-2 true rest/recovery days per week - Periodically reduce volume (deload weeks) - Don't add extra work if HRV is chronically low - Sleep 7-9 hours—non-negotiable

If you're already overtrained: - Extended rest (1-2 weeks of very light activity) - Address sleep, nutrition, life stress - Watch HRV to know when you've recovered - Return to training gradually
