One exercise seems to boost strength, energy, testosterone, and IGF-1 more than most gym routines yet almost no one uses it correctly

I notice my concentration is different after a poor night of sleep. Even normal training sessions can feel more difficult.

Sleep consistency matters a lot. Going to bed at completely different times every night can make recovery feel unpredictable.

I used to think recovery was mostly about protein intake but sleep plays a much bigger role than I expected.

Does anyone else notice that poor sleep affects coordination? I find it harder to stay focused during technical exercises.
