Saw a guy doing shadowboxing and bagwork wearing a weighted vest. Has anyone seen or tried this? The guy is 20 y/o ametuer with like 15 or so fights, so he's no novice. I thought this would be interesting to try, but would it affect you balance and give you the wrong "feel"?
There are better ways, of doing this type of thing. Tried it 40 years ago without success, increases impact. Best way is using woodys. Decreases impact, increases workload, improves Feel.
Rubber reduces the impact, it absorbs it. If you look the Knees are locked, what its doing is firing the TFL, its speed work.
