Re: MMA training
You have to train in a lot more.
If you want to be a well-rounded fighter that is....and in this day and age if you really want to get somewhere then you really would want to be.
Train in kicks and knees,wrestling for takedowns and takedown defence, sambo/BJJ for grappling and learning submissions.
Boxing/kickboxing/Muay Thai = Striking
Sambo/BJJ = grappling on ground
Wrestling greco roman/freestyle = getting your opponent to the floor or prevent yourself getting taken to the floor.
Compared to boxing you basically need to train in a hell of a lot more areas.
Of course in terms of physical conditioning things remain the same do roadwork/sparring/working the bags or mits, the same shit....
