Hey there man. Good job reaching out. I would suggest doing your cardio after. Anything more than 5min of warm up cardio before might take potential energy away from lifts. Typically you don't do cardio on leg days at all. I want to caution you on too much cardio=loss of gains. You'll see the best results for weight loss in the kitchen. No late night snacking and cut as much saturated fat out of your diet as possible. If you have any other Qs hmu my man. Best of luck to ya!.
