Some questions that I couldn't find in the FAQ.

Hi r/loseit, last week I started my journey and I've lost about 10 pounds so far on diet, three days ago I joined a gym and started working out but I'm not sure about the routine. I weight around 230 now and trying to go down to at least 180 atm so if I wanna lose weight fast(er) is it better to focus on cardio or lifting? So far I've been doing mostly lifting alternating days between chest arms and legs and running a mile on the treadmill afterward. Should I do more cardio and less weights? or same weights and more cardio? I'm more focused on weightloss than building muscle right now. Also I'm 5,11 19 and male.
