This post is simply to share my experience as a novice in weight training and is for those who are in a similar situation to mine. In short, it made me feel much better. That + getting 8 hours of sleep may be just what is missing to improve your mood (and probably your sex drive, too). I simply bought two pairs of dumbbells (10 and 15 pounds), training shoes, and a gym mat. I do everything at home, following YouTube videos, 20 min at a time, two or three times a week. I work 50 hours a week adnd have no time for the gym. There is a lot you can do at home with dumbbells (again, see YouTube) My goal is simply to feel better and to gain a bit of muscle mass (I was slim to start with and I am already seeing good results!). For those who are a bit older, it helps prevent age-related muscle mass loss. Take it from a total neophyte in this area who has been doing it for one month: it's worth it.
