You can do everything “right” like train hard, eat enough protein, stay consistent and still overlook the one thing your body needs most to recover.
Not every workout ends when you leave the gym.
A 2025 Nature Communications study analyzing over 4 million nights of sleep found that vigorous exercise close to bedtime was associated with delayed sleep, shorter sleep duration, higher nighttime heart rate, and lower HRV.
This doesn’t mean evening workouts are “bad.” For many people, they’re the only realistic option.
But if you’ve been wondering why you’re waking up tired despite training consistently, the answer might not be your workout—it might be when you finish it.
Recovery starts long before your head hits the pillow.
