I just traveled this past week. 6 days apart. Both flights were roughly 3 hours. I worked out once while I was away (3 days after first flight) and then right after I got back to town. Both times I felt my strength levels were substantially down. Diet stayed the same. Hydration could have been a bit better-I was in a warmer location but didnt seem to lose any water weight because my body weight was not down at all.
I slept perfectly every night and for plenty of hours each night. My strength might have been peaking right before I left-I was making PRs literally every time Id do a pressing movement. Not sure if maybe I did peak (I wasnt following any liner progression Id just try to top what I did the session before) or if air travel actually can, or does have this effect.
Anybody experience this before?
