Hi, guys! For those of you who do the kickboxing workouts, I'm wondering, does the air get compressed out of you when you punch or do uppercuts (or any upper body hitting movement, actually)? This is the case for me. As in, there's an audible "whoosh" sound, kinda like breathing out hard, but I'm not consciously timing my breaths. It doesn't cause any difficulties for me, but I'm wondering if I'm the only one.

Also, any breathing techniques for while kickboxing?

Thanks in advance :)
