Just like many fighters, Lacy might not have used weights as a part of preparation for the fight, but he did use weights separately, as a stand alone training.
He used them way to much in my opinion, why does he feel he needs to carry all that bulk for 12 rounds?
idk when that interview is from, but lacy used weights alot in his career. maybe he didnt at some point, maybe even now. but at some point he did lots of weights, common knowledge i thought. they talk about it like half his fight with taylor.
