Heavy lifting increases nervous-system stress, muscle damage, and overall recovery demand, so HRV often dips for a day or two afterward. That is not automatically a problem, but repeated hard strength sessions with no recovery room can keep HRV suppressed longer than expected.
No. A short-term drop can be a normal response to productive training. The useful signal is whether HRV stays suppressed alongside poor sleep, elevated resting heart rate, or heavy recent training load, because that combination is more likely to mean you should scale intensity.
Hybrid athletes create fatigue from two different directions at once. A run session may stress aerobic systems while a heavy lower-body lift adds muscular and neural stress, so HRV can look suppressed even when only one part of the plan feels hard subjectively.
