oxygen

[markas214]

I was working legs heavy today, 560lb hack squats, and got real winded on my last set. I was thinking that one of those portable O2 tanks would have come in handy. What do you think? Would I look like a real idiot? I am old anyway, 43.

i used to swim 2 events back to back in high school, the 100 back and 100 breast.. and used oxygen in the 4 mins i had in between.. worked wonders for me.

You would look like a fool. You don't need an oxygen tank. Why would you want to lug that around all workout.
