Can I adjust the resistance of the dummys arm side ways, up and down motion to move faster?
Yes, it is possible to adjust it to move faster. Earlier versions of this dummy were faster, however the problem is your attack and completion of your attack will need to always be faster than the dummies recoil to kamae. Otherwise you will get a shinai to the groin, throat or other sensitive areas, Its a VERY BAD IDEA for those reasons. The dummy is designed to be as safe as a mechanical kendo dummy can be. Always know where your opponents shinai is, you MUST always win and the dummy MUST always lose!
