On “How to improve block start. I can’t seem to stop that subtle right shin angle movement before take off. All critiques appreciated”
I'm going to disagree with u/blacktoise pretty heavily on the front leg only push. At 0:19 we see your knee drop and your foot pivot around the contact point on the block.

Dwight Thomas (at that time stamp) is checking out the athlete's block start and emphasizes the full contact on the back pedal. If the contact is there, you shouldn't move like you are right now. Push with both feet and take a slightly shorter step by keeping the right foot closer to the ground.
Besides the slight pivot in the foot, your set position looks really good! You push well and even though we can't see the next couple steps, it looks like you're putting yourself in a good position for steps 3 and 4.
