Mate, if you want to waste your time flapping around with light weights like the guy in the video, be my guest. BTW, I quoted the title of the video for a good reason.
I'd say Couture's conditioning program developed a pretty good work capacity for him. Sure it's not all he did. Plus, these probably build or maximize strength in muscles as they fatigue. If anyone has doubts: try them at least once. Before I tried them I thought they would be unchallenging. I was really wrong on that one. Now I'm a believer.
Understand the messages from the biggest organ, in the body. Then you will be on the right road to understanding the whole of it. .
If you think complexes and circuits look too easy to be effective try doing a round or two of them as a warm up before you do your "real" weight lifting. Just make sure you don't put down the bar until the circuit/ complex is complete, don't rest between the different exercises and go as fast as you can without losing proper form. Then don't rest more than 1 minute between rounds.
Are discussing weights for boxers or weights for MMA....two different and distinct fight games that required totally different training techniques
My POV is resistance training to increase work capacity for a period of time of about 2-3 minutes and a 1 minute rest period between work periods.
Might be worth a try. It took me 2:46 to complete one round 35lb bell which is close to the work duration of a 3 minute round. https://www.youtube.com/watch?v=ewanKnvNuOw
I'm not training to fight anymore but I've been using this + intermittent fasting diet and so far I like the result, my completion time is going down so I may need to go to a higher weight. The "thruster" and "swing" seem to work the core well. I like how it's weight lifting but also crosses over into cardio training, if done right it will really make the heart and lungs work.

There's a little bit of commentary about Kovalev's weight training at the beginning of the video. The commentators mention that Kovalev attributed his "poor performance" against Agnew to training with heavier weights. The heavier weights supposedly made Kovalev feel sluggish during the fight and Roy Jones Jr. states that the heavier weights "make you slower in the long run". https://www.youtube.com/watch?v=zP_5Pw8GFE0 The way I interpret Jones' statement is that if one conditions for power by lifting heavier weights then the body can't perform at its best once fatigue sets in. That's why I would choose a conditioning program over a strength program for boxing. One can increase power with heavier weights but strength may not be the better attribute to have in a boxing match. If you have followed boxing for a while you can probably think of some extremely powerful boxers who never made it near the top in spite of their power.
Boxing isn't powerlifting or bodybuilding, so you needn't concern yourself with weights at all. The best way to prepare yourself for boxing is by doing just that... Boxing.
If I remember correctly there were studies done that indicated amateur international boxing teams that weight trained had performance advantages over those that did not have weight training programs. Also, practically all top professional boxers do some sort of resistance / weight training definitely not power lifting or body building. I know Holyfield lifted weights at the World Gym on Richmond Avenue in Houston, Tx. I saw him do it.
