Can someone breakdown Mayweather's leaping left hook?

All I can say is what I was taught at my gym: when you jump with a left hook forward, you should land in such a way, that the weight is on the front feet. That gives power

 

i have been wondering about this too - bump -

 

From what I've seen from both, the front foot pivot thrusts them forward and the momentum that would normally just go into the punch also drives them forward as they turn the shot over. The back foot may also be used to push them forward but I can't really tell.

not sure about mayweather but cus d'amato was a huge fan of it and you can see it when tyson and floyd patterson fight. it's used in combination with head movement. it's set up with a slip or roll to the left (lead leg), with the weight in that lead leg, then propel forward with force generated from the lead leg, while the rear foot makes a gallop step forward for stability and creates base when the front foot returns to the mat.

you can see it here around 1:55 then they show it in slow motion.

Feinting first to bring the hands down usually works. RJJ leans in before jumping in as a feint to lower the guard and loop around it.

Floyd would feint his jab and leap forward with it

 

feint with a lead right (or back hand)... this will bring their guard up. with the feight, allow your weight to transfer to the lead foot and then "spring" off the lead foot and hook around the guard.

 

Roy was a master at it.

Mayweather threw a beautiful one against JMM which sent JMM down. Watch that punch and try see how he did that. Iv tried it in the gym and it's extremely difficult to do it well

 

:deal that's how he hit JMM with one. Quality shot so fast even JMM couldn't defend against it.

 

it's actually quite easy, and fun once you get it. practice slowly for a few minutes and you'll get it down no problem. the trick will be to use it in practical experience. but at the end of my suggested instructions you'll find "set-up" hints

1. get in position by dropping left (like a slip outside their right hand) and sit there for a few seconds and feel the load in the left leg with your right shoulder over your left knee (almost like a short twisting lunge)

2. don't concern yourself with the punch yet, simply take the load in your left leg and propel your body UPward (be patient and practice getting the position to initial movement down first)

3. then become conscious that your right foot touches first as you land in your stance

4. now turn the UP into a FORWARD and throw the hook. it's ok to over exagerate the move while you're learning. have fun with it.

5. now clean up the range and use a moderate propel forward (still from a loaded left leg, landing in your stance with your back leg touching first). this is more realistic. if your normal stepping hook takes 12" you'll be able to get 18-24" from a moderate "leaping left hook".

purpose: hitting your opponent who is backing up with their guard in front of their face

set-up: from the drop left. anytime you find yourself here know what is available for you (close-left upper to body, close/med-left uppercut to chin, med-upjab, far-leaping left hook). and there are sooooo many different ways to set the position with feints, as part of combination, from both offense and defense. that's why it's best to practice from the "position" (which is the left leg load) instead of from the "set-up to position".

does that make sense?
