There is a truism in MA (martial arts) and SD (self defence) that says "You fight the way you train". You could simply say you perform the way you train, whatever the activity.
I for one do not want to fight lying on my back with my hips and core immobile and using only my chest, tri's and shoulders to get out of there.
I'm loathe to recommend any particular exercises in a sport specific context. Want to punch effectively? Go Punch!
That said, when we training movements we create patterns that can be replicated with force and power in our chosen activity. When we train msucles...we train muscles.
We do not live and move in isolation. Why train that way?
This is simple but really important stuff. I've pointed to a few ideas on functional training in the past and quoted Vern Gambetta who has this same principle: Train Movements Not Muscles!
Vern Gambetta has a principle that states "Train Movements not Muscles". It makes sense. When the body moves all sorts of muscles are firing in sequence to move, stabilise and balance. Isolating a muscle is not how we move in real life. We move in squats, twists, pushes, pulls, bends and lunges. It therefore makes sense to train in those movements too.
