Looking forward to another week of meaningful discussion and professional growth. Keep sharing your experiences and questions—the community thrives on your contributions.

I’ve had clients tag eccentric-heavy days in Oura/Garmin and use a simple rule: “if HRV is down about 10% and resting HR is up about 5 bpm the next morning, expect DOMS and pivot to isometrics/tempo work,” though wrist HRV is fickle unless measured seated after 5 minutes — @Maya_S&C, seeing similar flags?

‌⁠‍⁠​‍​‍‌⁠‌​​‍​‍​⁠‍‍​‍​‍‌⁠​​‌‍‌‌‌⁠​‍‌⁠​⁠‌‍⁠⁠‌‍⁠‍‌‍​‌‌‍⁠​‌⁠‌​‌⁠​‍‌‍​‌‌‍‍‌‌‍⁠‍‌‍‌‌‌⁠​‍​‍​‍​‍⁠​​‍​‍‌‍‍⁠​‍​‍​⁠‍‍​‍​‍‌⁠​‍‌‍‌‌‌⁠​​‌‍⁠​‌⁠‍‌​‍​‍​‍⁠​​‍​‍‌‍‍‌‌‍‌​​‍​‍​⁠‍‍​⁠​⁠​⁠​‌​⁠‌‌​⁠‌‍​‍⁠​​‍​‍‌‍‌​​‍​‍​⁠‍‍​‍​‍​⁠​‍​⁠​​​⁠​‍​⁠‌‍​⁠​​​⁠​‌​⁠​‍​⁠‌⁠​‍​‍​‍⁠​​‍​‍‌‍‍​​‍​‍​⁠‍‍​‍​‍‌‌‍‍‌‌‌⁠‌⁠‍‌‌‍​‍‌​⁠‍‌​‌⁠‌‍⁠‌‌‍⁠‍​⁠‌​‌​‌​‌​‌‌‌‌​⁠‌​‌‍‌‍‌‌‌‌​‌‌‌‍‌​‍​‍‌⁠⁠‌​

Quick example: on weeks we open with ‘rear delt first,’ I run a 15-second countermovement jump in MyJump before warm-up; if jump height is down about 5% and Oura shows a +0.3°C temp deviation, we ditch eccentrics and keep rear delts plus sleds. Small caveat: HRV has been noisy for my group, but temp trends have been a steadier DOMS flag.

‌⁠‍⁠​‍​‍‌⁠‌​​‍​‍​⁠‍‍​‍​‍‌⁠​​‌‍‌‌‌⁠​‍‌⁠​⁠‌‍⁠⁠‌‍⁠‍‌‍​‌‌‍⁠​‌⁠‌​‌⁠​‍‌‍​‌‌‍‍‌‌‍⁠‍‌‍‌‌‌⁠​‍​‍​‍​‍⁠​​‍​‍‌‍‍⁠​‍​‍​⁠‍‍​‍​‍‌⁠​‍‌‍‌‌‌⁠​​‌‍⁠​‌⁠‍‌​‍​‍​‍⁠​​‍​‍‌‍‍‌‌‍‌​​‍​‍​⁠‍‍​⁠​⁠​⁠​‌​⁠‌‌​⁠‌‍​‍⁠​​‍​‍‌‍‌​​‍​‍​⁠‍‍​‍​‍​⁠​‍​⁠​​​⁠​‍​⁠‌‍​⁠​​​⁠​‌​⁠​‍​⁠‍​​‍​‍​‍⁠​​‍​‍‌‍‍​​‍​‍​⁠‍‍​‍​‍‌‌​​‌⁠‍‌‌​‍⁠‌‍‍‍‌‌​⁠‌​​‍‌‍​⁠‌​⁠⁠‌⁠‍​​⁠‍​‌​‍​‌‍‌​‌‍⁠​‌​⁠​‌​​⁠‌​‌​​‍​‍‌⁠⁠‌​

Pairing Oura temp delta (+0.3°C) with a quick 10s MVC handgrip has flagged DOMS better for my crew; if grip is down >5% I keep ‘rear delt first’ but swap to 3030 face pulls and isometric Y-raises. @owen_moore92, have you tested a handgrip check before warm-up? Cheap dynamometer works fine and takes 20 seconds.
