Critique my sparring

[MilitantWorker]

Does sparring the heavybag (and shadowboxing) help to workout the footwork necessary to get into range to throw hooks and uppercuts without getting hit.
Basically, what are some good ways to integrate slipping and weaving into footwork while moving forward. I feel like I have to rush in to throw hard hooks and uppercuts

in brief, no. heavy bags are for perfecting your punching technique.

slip bags and speed bags however, are designed for that exactly. ever seen Tyson with what looks like a bulls nut sack swinging from the ceiling? its different from the speed bag (which is attached to the floor also) and mainly what you do is swing it, throw punches, change angles and try avoid it hitting you in the head

also, learn the difference between lead hand punches, and rear punches. lead hooks for example are good for opening and closing combos when you are in tight.

hope this helps.
