>his Your post? Yes. It's short and while correct in meaning is lacking in intention. You can train your brain all you want. Every day, for hours and hours and you will gain from it. But you will gain nothing in terms of immune system, cardio, respritory, metabolism, tissue health, organ health, muscle health/mass, bone health/density. You can strength train all you want. Every day... and you WILL BENEFIT in every single area I listed.
