I do my sprint sessions 2x a week, how many times per week should i be in the gym?

I am a 400m athlete & at the moment i’m in the offseason, so currently i’m doing 5x per week weight training in the gym. I don’t want to burnout or be lacking recovery for my sprint sessions. And i’m not sure if 5 days is too much.

When track season starts, what is the optimal amount of times per week should you be in the gym to ensure best performance on the track?
