I wish I could remember. I could do this without thinking in elementary school. Now I'm an older, uncoordinated person that can only hike and bike

I think, try to breath "normally" if that makes anysense. Perhaps on the upstroke or the downstroke of the jump. I think the speed affects the breathing too. Perhaps slow down so your not going superfast but somewhere in the middle.

Those are my recollections. I hope they help.
