I've been going to the gym for the past 3 weeks and I think that I've created a random routine. I feel like I'm getting stronger but I want something more concrete of a routine. Now I currently do Decline/flat bench, curls, pull down, abs,row and work on my legs. Is this a good rountine to help build up my muscles, not really focused on weight just want to turn the fat into muscle. What do you guys recommend?
