Couldn’t do as many lifting reps with less food.
There may be a psychological factor involved, as that was what I expected: strength athletes tend to eat at regular short intervals, and deliberately overeat over the course of a day to make sure they have the optimum amount of calories and nutrients to build muscle – they later undertake a cutting phase to lose the fat.
Runners need to be sparrow-like, as light as possible to optimise the power-to-weight ratio. Carrying excess muscle around is not optimal.
I want to be both agile and strong, rather than ideally adapted for one function.
