Joe Rogan argues that the most effective way to improve physical conditioning for high-level athletic performance is to train at sea level while sleeping at altitude.

“The move is sleep at high elevation, but train at low elevation. And the reason for that is when you train at low elevation, you have more oxygen, you can get more reps, you can put in more rounds, you can put in more work.”

Brian Simpson believes that proper diet, rather than exercise alone, is the primary factor in losing weight.

“But the real way you lose weight is your diet.”
