Complete Guide to NDA physical fitness requirements 2026

The National Defence Academy (NDA) physical fitness requirements mandate that candidates meet stringent medical and physical standards, including specific height-weight ratios, visual acuity, and absence of chronic diseases. Candidates must pass a physical endurance test, including running, sit-ups, push-ups, and pull-ups, to qualify for admission into the Army, Navy, or Air Force.

What is the Exam?

The National Defence Academy (NDA) examination is a premier national-level entrance test conducted by the Union Public Service Commission (UPSC) twice a year. It serves as the gateway for young aspirants to join the Indian Armed Forces—Army, Navy, and Air Force—as officers. At Exam Bhai, we view this not merely as an exam, but as a gateway to a life of honor, discipline, and national service. The selection process is bifurcated into a written examination followed by the highly rigorous Services Selection Board (SSB) interview, which evaluates the candidate's psychological, intellectual, and physical capabilities.

Eligibility Criteria

Official physical standards are strictly governed by the UPSC guidelines available at upsc.gov.in.

• Height and Weight: Minimum height is generally 157 cm (with relaxations for specific regions). Weight must be proportional to height as per the standard BMI chart provided in the official notification.
• Vision: 6/6 in the better eye and 6/9 in the worse eye for Army; 6/6 in both eyes for Air Force/Navy (without glasses).
• General Health: Candidates must be free from any disease or constitutional affection, which might impair efficiency or necessitate medical boarding.

Application Process

1. Visit the official website at upsc.gov.in.
2. Register via the One-Time Registration (OTR) portal.
3. Fill in personal, educational, and communication details.
4. Choose the preferred service branch (Army/Navy/Air Force).
5. Submit the application fee and take a printout of the confirmation page.

Preparation Strategy

Success in NDA requires a blend of mental preparation and physical training. We at Exam Bhai recommend the following:

• The 80/20 Rule: Focus 80% of your energy on high-weightage topics in Mathematics like Calculus and Probability.
• Daily Fitness Routine: Do not wait until after the written exam to start your fitness journey. Engage in daily running (5 km), push-ups (at least 20), and sit-ups.
• Mock Testing: Integrate advanced mock tests for Defence aspirants into your weekly schedule to build stamina for the 5-hour long examination day.

Cut-Off Trends

According to historical data published on upsc.gov.in, the qualifying marks fluctuate based on the difficulty level of the paper and the number of vacancies. Generally, a score between 350-400 out of 900 in the written stage is considered a safe zone for securing an SSB call. We advise students not to focus on the "minimum" cut-off, but rather aim for 450+ to ensure a higher rank.

Frequently Asked Questions

Q1: Can a candidate with spectacles apply for the NDA? Yes, provided the vision is correctable to 6/6. However, for Flying Branch (Air Force), the standards are stricter.

Q2: Is there any height relaxation for candidates from North-East India? Yes, the official notification at upsc.gov.in specifies height relaxations for candidates from specific tribal belts and hilly regions.

Q3: What is the physical test schedule during the medical examination? Candidates are tested for running, push-ups, sit-ups, and rope climbing. It is a pass/fail assessment to ensure physical robustness.

Q4: Is it necessary to have Mathematics in 12th for the Army wing? No, for the Army wing, you can apply with any stream. However, Physics and Mathematics are mandatory for the Navy and Air Force wings.

Q5: Can I improve my physical fitness after clearing the written exam? The time between the written result and the SSB interview is limited (typically 2-3 months). We recommend starting physical conditioning at least 6 months before the exam.
