I'm fairly new at these as yesterday was my first time doing more than one since I finally figured out the false grip as well as how to control the descent. After seeing myself in the video it looks like I have an issue fully extending elbows at the bottom with the false grip. While doing them I thought I extended as far as I could but apparently still some bend in elbows, does turning your hands out at the bottom help? I've just read about that.
