I wonder how much difference physical stress Vs mental stress it makes. Stress is stress. Anxiety (mental stress) causes physical symptoms. The will to continue in physical endeavours is through changing the mind and being determined to continue. Mind over matter. This want to stop doing physical stuff comes from the mind. So improving the mental toughness comes from repetitively attempting to breach this barrier.

Goggins even says stuff in his interviews with Joe Rogan that indicate that he would agree. Most people stop physical activity not when the body is exhausted but when the brain thinks the body is done. When Jesse Itzler interviewed with Joe Rogan about Goggins, he said Goggins thought people only did 40% of what they were capable of until they changed their mind.
