I have to disagree with both of you here. All my life, I have tried to find the "faster ways". If there is a faster way, I would like to learn it myself.
If you train this traditional art partner drill over 10,000 times, you will develop this skill. How and where can you find a "faster way" than this?
If you twist this sand container 10,000 times, you will develop strong twisting power used in wrestling. How and where can you find a "faster way" than this?
Please tell me if you can find any modern gym equipment that can help you to achieve this goal.
