Ninja, or practitioners of ninjutsu, engaged in various physical training exercises to develop the strength, agility, and endurance required for their demanding activities. The training regimen was designed to enhance their overall physical abilities and prepare them for stealthy movements, combat, and survival in different environments. While the specific exercises may have varied among different ninja schools, some common elements of ninja training include:

1. Martial Arts Training:

2. Stealth and Evasion Drills:
   • Ninja practiced stealthy movements, such as walking silently, crawling, and navigating through challenging terrain without making noise. Evasion drills focused on quick, agile movements to avoid detection.
3. Cardiovascular Conditioning:

7. Endurance Training:
