Kickboxing, it teaches amazing focus and mind to muscle connection. Back yonder when I kicked boxed. My little ass didn’t reach a high level but I bloody enjoyed it and still to this day no matter where I’m training, especially when traveling, I always warm up with shadow boxing and shadow kicking, like here on a hostel rooftop in Nepal.
It loosens joints, warms and stretches and it also focus your mind and muscle (Arnie’s preachings)
Give it a go and see how warmed up you feel before training
