I am annoyed by myself and I don't know what to do anymore.Help.

I am a sophomore and I have been going to the gym for some months. My batchmates utilise the time I spend in gym to do coding. They give contests and have improved DSA to such a point that if I can do 1 question, they will solve 3 questions in that time. If this goes on, I won't be able to grab an internship in the next semester. I am thinking I should quit GYM and focus on coding. I dont know what to do now. Should I quit ? (sorry for bad english)
