I run 25k a week and do about 100 crunches a day, maybe some pushups and resistance bands if I remember to. I tend to just listen to my body. 2 meals a day, usually a big meal in the evening and a small breakfast/lunch.
Protein post workout and a good mix of carbs, fibre and protein all the rest of the time.
They absolutely do not. It’s provided vast quantities of harmless joy.
