fast, agile and explosive. Your strength should also increase as you train. You will also build upper body strength with the climbing equipment they use. Here is one piece of equipment they use

Believe it or not, there are ninja training seminars out there that teach you the in’s and out’s, the do’s and don’ts of becoming a ninja. In a ninja seminar, they don’t just teach you some stealth fighting skills, they also teach you the ninja way of life. If you want to train in a ninja camp, be prepared to take some time off work because most ninja seminars are held at remote places and can last from one week to several months.
