Kumar made his international debut in 2003 at the Asian Championships held in New Delhi, India. Competing for India, he quickly established himself as a formidable wrestler. His dedication and skill earned him numerous accolades over the years.

In 2011, Kumar was honoured with the Padam Shri Award. He also received the Rajiv Gandhi Khel Ratna award in 2009, India's highest honour for sportsmen. Additionally, he won the Arjuna Award in 2006, which is India's second highest national sports award.

National Firsts and Major Wins

Kumar became the first freestyle wrestler from India to win three gold medals at the Commonwealth Games. He achieved this feat by winning in the 74kg category at the 2018 Games in Gold Coast, Australia. Previously, he had won gold medals in the 66kg category at the 2010 Games in Delhi and in the 74kg category at the 2014 Games in Glasgow.

In another significant achievement, Kumar became the first Indian wrestler to win gold at the World Championships. He claimed victory in the 66kg category at the 2010 edition held in Moscow, Russia.

Challenges and Injuries

Kumar's career has not been without challenges. He suffered a knee injury that ruled him out of the 2018 Asian Championships in Bishkek, Kyrgyzstan. A shoulder injury also caused him to miss about a year of competition following the 2012 Olympic Games in London. Additionally, another shoulder injury prevented him from competing in the 2010 Asian Games in Guangzhou, China.

Personal Life and Philosophy

Residing in New Delhi with his wife Savi and their two children, Kumar balances his life as an athlete and a railway worker. He speaks both English and Hindi fluently. His sporting philosophy is simple yet profound: "Perform to your potential, don't get bogged down by the pressure of expectations. Stay positive and have the right attitude to win."

Coaching and Training

Kumar trains under several coaches, including Jagminder Singh (national), Vladimir Mestvirishvili (personal), and Satpal Singh (personal and father-in-law). His association with Indian Railways under a sports quota programme allows him to train and compete internationally.

Future Ambitions

Looking ahead, Kumar aims to win a third medal at the Olympic Games. This ambition reflects his enduring commitment to wrestling and his desire to continue representing India on the global stage.

Kumar's journey from a young boy inspired by his father to a celebrated athlete is a testament to his hard work and dedication. His achievements have not only brought him personal glory but have also elevated Indian wrestling on the world stage.
