With a 9 to 6 and a long commute, mornings gave me steadier adherence and fewer afternoon dips. I did short sessions right after waking and got a reliable energy lift by 10 a.m. Evening workouts worked only if I kept them easy and ended at least 3 hours before bed. Any hard session after 7 p.m. made it harder to fall asleep and raised my heart rate overnight. On weeks I slipped to evenings, I skipped more often due to late meetings, traffic, or dinner.
If I were starting over, I would run a minimalist morning plan on weekdays and a slightly longer one on Saturday. Weekday template: drink water, stand by a window or step outside for 5 minutes, then do 20 minutes in the living room, 3 rounds of 40 seconds work and 20 seconds rest of bodyweight squats, counter push ups, backpack deadlifts, split squats, and a plank, then a 5 minute brisk hallway or stair walk. Keep it apartment friendly by controlling foot noise and using a backpack for load, and set clothes and shoes out the night before to remove friction. To reduce afternoon crashes, add a 10 minute walk right after lunch, keep caffeine before 2 p.m., and eat a protein plus fiber lunch instead of a heavy high fat one. If you prefer some evening work, keep it to mobility and an easy 20 minute walk, stop by 7 p.m., and reserve any harder effort for Saturday morning when you can be in bed by 10 p.m.
