grog, are you breathing in as you push upward? Just making sure I'm interpreting your post correctly.

I have no idea if I'm doing it right but I do a forceful exhale through my mouth as I push up. This does two things for me: 1) I must breathe or die and 2) it seems to help me belly breathe mo' bettah. Oh yeah, this also help me maintain a rhythm which just helps the overall effort.
