I don't know enough about them to be honest. But here's what I do know.
I know I am cheap and they are expensive. I know they smell and I don't like being smelly. And I know they are hard on your lungs, and well, I am a big fan of breathing, it makes high rep squats much easier when your lungs work.
James 1:16-17 ESV
Do not be deceived, my beloved brothers. Every good gift and every perfect gift is from above, coming down from the Father of lights
With God's help...Mens sana in corpore sano
