The lat and tricep muscles are connected to the heart chakra and represent how we have our own back in matters of our heart.

The saddle bag arms you experience are connected to the shoulders being rotated out, lat muscles subsequently disengaged, and/or the upper arms tucked tight next to the sides. This represents giving a lot of your love away in order to feel loved.,

You are emotionally training yourself to make sure your back is taken care of before extending yourself outwards.
