Haven't done yoga, but will do various types of cardiovascular exercises (jogging, walking, stationary-bicycle, swimming, etc.) several times a week. Plus, it helps me to do weight-lifting weekly as well.

When shooting factory 9mm ammunition, I normally use Blazer aluminum case rounds . They always make the required power factor in both IDPA and USPSA. Plus, I don't feel like I'm wasting good brass.
In approximately four years, I added almost 200,000 miles on my car from attending matches. This included local pistol and rifle matches, as well as bigger matches in other states. I'm trying to be more efficient now days with travel expenses.
