There’s no doubt that getting stronger helps these guys, Bolt too, but I think some of the confusion happens when everyone starts thinking they are doing heavy doubles and triples or are surprised to find out they are doing pretty generic strength routines. People are surprised when they see someone doing leg press instead of squat or hammer strength bench instead of barbell but the thing is, they don’t need much, they just need a basic strength increases and some injury prevention.
It seems like everyone, especially former powerlifter or weightlifter gym rat type guys think athletes should be doing tons of heavy heavy sets when in reality they probably are not doing that and probably should not. That old weights follows speed thing that CF always talked about.
If you do 5x5 or 4x6 at 225 week one and 8 weeks later you are doing 5x5 at 235 that’s proof you just got stronger and never did nor do you have to max out.
