Started with a 55kg / 121lb bag around 4 or 5 months ago. Good to be moving my new bag filled a bit over 80kg / 176 lbs. This is my final set of the day. I seem to be hitting my chest with the bag. Is this normal or is my form no good? And thanks all for the motivating posts which helped me improve.
Didn't actually notice I whack my chest with the bag until I took the video.
