Basically the thread title says it all. I'm early 40s, could stand to lose 20 lbs and have become stiff from inactivity. I'd like to try bjj but I don't know if I could hang. It's closer to me than the aikido school, but I've heard aikido is good for "old people" lol. I've got some mild carpal tunnel too and most mornings I wake up with stiff joints, especially my knees. I'm really leaning towards bjj but I don't want to get injured because I'm like a board! Is bjj good for loosening a person up? How about aikido?
