A few weeks ago I posted asking if anyone else found Garmin recovery data hard to actually use for lifting decisions. Got some great responses and a few people doing similar things, so I committed to it properly for 3 weeks. Here's what changed.

The setup is simple. Every morning I check Body Battery, HRV, sleep score, and training load ratio on my 255. Based on where those land, I pick one of five session types, heavy strength, moderate strength, conditioning, zone 2, or recovery work. No overriding the numbers because I "feel fine."

The hardest part was the first two weeks. There were days I walked into the gym ready to go heavy and the numbers said moderate. I did moderate anyway. It felt wrong honestly, like I was leaving gains on the table.

Then around week three things clicked. My working sets started feeling cleaner. I broke through a bench plateau that had been stuck for three months. The sessions where I held back were the ones actually driving progress, not the ones where I went all out.

The biggest thing I learned: I was overreaching 2-3 sessions per week without realising it. I'd feel mentally ready but my HRV and sleep were telling a different story. My ego was making training decisions my body couldn't back up.

I'm on a Forerunner 255 so no Training Readiness, just the raw metrics. Honestly that's been enough. You don't need the fancy composite score, you just need rules for what to do when the numbers are high, mid, or low.

Still refining the thresholds but the pattern is clear: respecting the data beats going by feel, at least for me. Anyone else been running something similar? Curious how others are drawing the lines on when to push and when to pull back.

sounds counterintuitive but hear me out.

for years I've been programming my own training... picking exercises, deciding volume, choosing whether today should be heavy or moderate based on how I felt. I'm on a Forerunner 255 so I've always had the recovery data (body battery, HRV, sleep, training load) but I never really used it beyond glancing at it.

2 weeks ago I changed my approach completely. I stopped choosing my own sessions. instead I feed my garmin recovery metrics into a readiness scoring system every morning and let it decide my session type, exercises, sets, reps, everything. I just show up and do what it says.

the results have been surprising:

• I'm training heavy less often than I would have chosen myself, but when I do, the sessions are noticeably better. turns out I was going heavy on days my body wasn't ready for it way more than I thought.
• my HRV trend has stabilised for the first time in months. it used to bounce around week to week. now it's holding steady which tells me the load management is working.
• I haven't had a session where I felt completely gassed halfway through. that used to happen at least once a week. the intensity is being matched to what I can actually handle that day, not what I want to do.
• the hardest part was trusting it on days I felt good but the data said "moderate." those ended up being the most important days to hold back because the following day I'd have a much better heavy session.

the biggest mindset shift is accepting that how you feel isn't always the best indicator of what you should do. your nervous system can feel fine while your HRV is trending down and your load ratio is creeping up. by the time you feel it, you're already overtrained.

I'm not saying everyone should stop programming their own training. but if you've got the garmin data and you're not using it to drive your session decisions, you're leaving gains on the table.

curious if anyone else has tried something like this.. fully handing over session selection to their recovery data instead of their own judgment.
