>Lifting in the morning derails the day. Cardio is fine, but if I lift weights in the morning, the rest of the day I’m running on -40 IQ points. The most cognitively demanding thing I can do is wash the dishes. I’m not sure what the physiology is: maybe it’s exhaustion of the glycogen stores, or fatigue byproducts floating around in my brain, or the CNS is busy rewiring the motor cortex. The point is that I try to do the cognitively-demanding things in the morning and lift in the evening.
This is a phenomena that 100% affects me. I tell this to people who say that exercise makes you more energized, and generally, they just don't believe me. Is there more study on mental fatigue after weight lifting?
Also, this whole article was very valuable. Thanks for sharing it.
