The Kick-Boxing sport uses stand-up striking along with various clinching techniques.
The "Aashayein" actress has been appointed as the brand ambassador for the Indian Muay Thai Federation 2016, for its Women's team.
When asked if kick boxing needs to be promoted more in the country, Sonal told PTI, "From hockey to football, all other sports have faced this struggle. We now have a kick boxing team as part of the Asian Games in 2018 but many are unaware. I am glad someone like Shah Rukh Khan has supported this championship. This will help reach a wider audience."
The actress says she practises kick boxing herself and is hopeful her association with the sports will help throw light on it.
