Increases in Physical Energy, Virya

I had conjectured that a few things could increase my energy. Lately, I wonder about physical and mental energy. I thought of reading as expending effort, but I realize now reading is mostly a mental activity. Aside from physical activity, what activities can help with energy? Here, I ask specifically about: - Meditation's effect on physical energy and vigour - Any other activity potentially linked with energy and vigour: possibly chores, activities involving movement, activities not involving movement, etc. Thank you.
