If we're talking weight loss, is it better to do cardio, weights, or both?
Diet will be more important than any of it.Ultimately though you'll want to do both. Cardio to increase the fat burn and some weight training to maintain your lean mass.
Both but don't expect to put on lots of muscle if your primary goal is weight loss.OP's pic's body looks just like mine, and I'm a thin bastard desperately trying to gain lol
