I started aikido a couple of months after my husband, and I can only recommend it to any other couple - it is soo much cheaper than partner therapy
Seriously, we work great together on the mat (umm..., off the mat as well, of course
), and we will be each otherīs uke at our shodan tests later this year. It is great to share that.
OTOH, I also know couples that donīt like to practice with each other, but in most of their cases one of them is much further advanced and the other one feels patronized by them
