Energy and diligence I'm wondering what the best ways to increase mental and physical energy are. I'm often fatigued, and feel slightly lethargic quite often. I have a lot of energy for intellectual tasks, but seemingly, I am fatigued by mundane chores or such things. I also lack willpower for resisting certain tasks.

I believe that a good way to deal with this would be to simply commit to exercising more, but I wonder if there are other ways that Buddhism recommends.

Thank you

Edit: I think my previous post on lying might be relevant. Could it be that integrity--something encompassing effort, willpower, honesty and consistency--be something that I am currently lacking? Something akin to, perhaps, virya? I'm not sure. Any thoughts?
For mental lethargy you can try the techniques to abandon sloth and torpor.

To overcome physical lethargy you can do walking meditation with a quicker pace.
