This is why I do not work without a coach anymore. And a good coach actually. I pick up too many bad habits trying to practice without direction and constant corrections.
I also noticed you being non relaxed in the previous threat. Your movement does not come naturally. There is a ton that can be said about head movement - but most importantly it has to be done very gently and relaxed, not forced. If you are forcing yourself to head movement you better clinch or run afterards or attack immediately. There is no point to dril head movement after head movement or pivot after a pivot. You can drill pivot and then run out, pivot and attack or pivot and clinch.
I also mentioned in the previous topic about the great deal my coach paid to me on being more straight and relaxed. I was in a class with an amateur MMA fighter and we got the same schooling on walking. The freaking coach tought us how to walk and then implemented that on a boxing warm up drill for back relaxation and then we did that for half an hour.
The drill is simple - hands up in a guard, step forward with left foot - strike right, step forward with the right foot over stepping the left (simple walking) and strike with the left hand forward. It has to feel natural like you are walking - very relaxed, without any tension. Repeat going back, repeat going forward. Do it for 30 mins non stop if you have to - you have to get to a very relaxed state where it feels non tiring, relaxed, guard up, chin down, staying up and hight, like a man.
Not much to comment and practicing defensive movement such as pivots or head movement. They are advanced stuff that need to be coached by a good coach who can observe and correct you so you do not pick up bad habits. But by no means they are forced movements in general. You can force them, but then again - run, hit or clinch after forcing it.
I have been tought basic distance dispersion or how to candle forward and backwards drawing hits and countering. Again these were not forced movements, but basic tactical drill which required nothing forced you stand with head slightly leaned forward a bit front foot heavy, and you draw your weight back wards to the back leg while hopefully drawing jabs. Then you move centrally and jab or cross. Simple. Nothing to force your body about.
