My first set of arch body hold is always the toughest one to get into the correct position. It feels like my muscles do not want to fire correctly until the second set. My current warm up is about 10 minutes long and I go through moving all my joints head to toe, do some body weight squats, cat/cow, hip circles, etc. and add in some QM movements to get my heart rate up.
Any suggestions to get warmed up specifically for this movement? Everything clicks into place either late in the first set of the hold, or sometimes not until the second set.
