Do boxers train legs heavy?

[boxer1234]

Mike Tyson used to do squats with weights.

Heavy Squats can be good for all athletes, and are the best exercise for gaining raw strength in the legs. But you have to make sure you are also working on speed/flexibility/explosiveness etc. So going too heavy, too often might not be the best thing. It depends on your goals.

I always though Bruce Lee neglected his legs
Heard he could only squat 60kgs

I think Bruce trained just about every muscle in his body, he just didn't train to be able to left very heavy weights.

good point
