Routine to lose belly fat

In my experience abs just come as a result of cycling and being lean. I am well defined in my abdominals and obliques and do absolutely nothing year round for them. Personally, unless this is a weakness or the off season, I think it’s a waste of time particularly if weight loss is the goal. Loosing weight and cycling 15+ hours a week is all that was needed for me at 47, 175lbs and 6’1 (off season weight 185lbs).
