r/losingweight

I want to start going to the gym and i have a routine set up. I really want to lose weight (at least lbs). Just to start off and get into the habit of going often though, would it be good to start with cardio only? I was thinking about going for a little bit and doing just cardio while there to get used to the gym and get into the habit of going in general. Would this help me lose any weight at all? I’m not fully sure how much of weight loss works in general and would be extremely open to any advice or any tips people may have for me. Thank you sm in advance!
