Started using mySASY alongside Garmin as an additional recovery signal.

Current split:

• Garmin - passive, continuous trend data: overnight HRV, resting HR, sleep, stress, training load.
• mySASY - standardized morning HRV measurement with HRM-Pro plus a more explicit training recommendation.

So far both systems have told the same story.

During the post-infection slump, both showed poor recovery. When the rebound finally came, Garmin metrics improved sharply and mySASY moved into supercompensation (myCompensation: 131) and recommended increasing training load rather than staying conservative.

The morning measurement is useful because the protocol is more controlled from day to day. That does not automatically make it “better” than overnight HRV - just a different, cleaner measurement context.

For now the rule is simple:

Use mySASY as another sensor, not an oracle.

What matters is convergence between morning HRV, Garmin trends, resting HR, actual performance, and how training feels.

Unplanned break: Kefalonia, then infection immediately after returning.

Recovery

• Back from Kefalonia: July 23.
• Heavy runny nose / infection from July 24; symptoms mostly gone by July 28-29.
• Running form dropped hard.
• Resting HR: about +4 bpm at the worst point.
• HRV: about -30% at the worst point.
• Strong rebound only came 8-10 days after the infection itself had ended.
• August 8: resting HR down ~3 bpm, HRV back from ~110 to 138; still ~130 the morning after a very heavy gym session.

Training adjustment

I did not try to catch up.

• Strength: repeated Week 3 for two consecutive weeks.
• Running: ~50% volume, then ~75%.
• Today: likely back to ~100% because the recovery metrics finally agree.

Unexpected result: legs

After roughly two weeks without heavy leg work:

• 120 kg leg press, previously a real working load, suddenly moved like nothing.
• 150 kg moved explosively - it felt closer to a warm-up weight than a working set.
• 65 kg squat also felt materially easier.
• Knee-height box jumps for sets of 8 are now comfortable.
• Hip thrust did not show the same rebound.
• Upper body did not show the same rebound either.

Second time I have seen this pattern.

Working hypothesis: my legs may accumulate enough fatigue from running + strength work that a longer break exposes strength that was already there.

Operationally: keep continuity for running and upper body, but test whether legs benefit from deeper periodic unloading.
