when it's atemi waze such as Lee's training, I understand how you can simulate that in the dojo by using gloves and pads. But with Ju Jitsu it's not really practical as the throws and especially locks cannot be done 'alive' as it's too dangerous. I know that sounds really poncey but you agressively hip throw someone on a wooden floor then slap a figure 4 on means one broken uke.
This is why I feel perhaps I did to complement the JJ with a more striking art. But there are a lack of MMA clubs where I live plus I have family commitments and stuff. It's a tough one
