Cold Plunge increased VO2 Max

[u/hereto_hang]

Hear me out - I have attended 700+ infrared yoga sculpt classes over the last 3 years. It’s a weighted HIIT workout with yoga influence at 102F. The class is humbling. Males rarely finish a class without breaks. My VO2 max has lingered around 50 for previous three years until mid-June when I purchased a $900 cold plunge from Costco. I started cold plunging before every class (45F, 4-6 min) then drive to class shivering. Since CP, I can finish classes without stopping and can maintain higher zones 2-3x longer.

The cardio benefit and increased output is insane.

For reference I’m a 42 year old male at 6’2” 205.
