Its quite hard to move at first, but then it gets easier.
(Katai Omori) Leg Weights
Type: Weapon/Supplementary
Rank: A
Range: Short
Chakra: 30
Damage: N/A
Description: The Leg Weights used for Special Taijutsu Training with Added Weights are made through the application of a sealing formula to ordinary leg weights. The sealing formula is used to, through the use of chakra, increase the weight of the leg weights to the desired level. The seal can't be applied to anything other than the leg weights and its use is restricted to its original purpose. One can remove the leg weights but the sealing technique in them stays active indefinitely and can't be released. Additionally, the Leg Weights and their unique seal calibration makes them only usable by the ninja to whom they belong. They can't be sealed or stolen.
So now you need to get accustomed to the weights for a month. Within the timeframe, show me at least a taijutsu only fight of your to see how you honed your adaptation to the weights.
