I'm thinking of switching up my routine. I usually do specific parts on specific days. Which I don't have issues with but I feel like I just need to cut and not bulk. I'm not gonna gain any more weight and I've been just maintaining consistency. I'm not fat either, I'm around 178. My diet could improve but I maintain weight and stay active at work too. But must of my fat goes to my stomach. Not like I have a big stomach but I know I can improve on it. I'm thinking of just sticking to mostly core and cardio exercises with some full body stuff like bench press, squats and deadlifts. While eliminating things like arm day and back day. Would this be wise or should I just keep working on every body part with more emphasis on my core since that's my main area of weakness? I know a six pack is tough to achieve but I'd be happy with even a two.
