My 1 year Krav Maga membership, a self defence system. Went from heavy smoker, no-cardio-at-all-person to feeling confident because I know how to defend myself, picked up running, swimming and regular body weight exercise on the side. Looking and feeling pretty good nowadays. More energy, brain activity, focus. Defo most bang for the buck.

Similar, I put down a $1000 for a year of Brazilian Jiu-Jitsu. Doing something like that is a lot more fun and life changing than just lifting weights at a gym.
