Its important to switch up your sparring intensity. Sparring slow develops the finer details of technique and teaches better reaction to movements. Hard sparring increases toughness and gets you ready for a real fight..those beatings are important and will let you know how far u wanna take it.
Didn’t think I would see training advice I agree with on a hip hop based forum, but I couldn’t agree with this more.
When you train with Muay Thai fighters from Thailand, they spar at 40-50% and focus strictly on technique and rarely ever spar hard.
Americans vastly underestimate the importance of light sparring.
