+10 to Krav Maga. From a second person perspective:

My partner has been doing KM for 2-3 times a week for over a year now and since then I see clearer thinking, responding instead of reacting, better sleep quality, losing weight as her gains. I am inspired, while I play badminton 3-4 times a week for 3/4 to an hour to stay sane, needless to say she finds time to play with me!

@jnsaff, I would say stick to KM and kudos for cultivating such a habit.
