Slept badly? Move your session to the morning if you can.
A meta-analysis of 69 studies found sleep loss (6 hours or less) lowered exercise performance, by about 0.4% for every extra hour you’d been awake. The interesting bit: afternoon and evening sessions took the hit, while morning sessions were largely unaffected.
→ Rough night? Train early
→ Can’t? Keep the session, lower the expectations
→ Then get the sleep back
Study: Craven et al., 2022, Sports Medicine.
