If you were in an actual match and your shoulders are these, you're going to burn them out much quicker as well. And the weird front foot pivot is messed.
Never tighten your shoulders, no need to turn foot on a jab and if you are a righty i prefer having left leg at front so your dominant hand (right) have more area for a power punch but its your preference
left leg at front and twist waist while trowing jab and while throwing it keep your shoulder a bit up so that u r blocked to some extent just beginner said what i learned
Decent video but shoulders should always be relaxed until needed to gaurd or throw a punch unless your not very good at masking your small movements then ig the tight shoulders can help you not sure tho
I think you shouldn't tighten your shoulders and do not tell beginners exactly how wide their stance should be as I think it develops naturally when you start to find your style (as a soviet boxer I have very wide stance) + I don't think you need to turn your foot when jabbing as it makes everything little slower but that comes to style.
You don't just hit pivoting your rear leg....you may take a chance, but you won't survive getting hit with all your weight on front leg....you're not creating any soace with your jab,defeating its very purpose.
