Don't make the mistake of trying to build muscle and lose fat at the same time. Do one or the other. Performing intense cardio will greatly hamper hour muscle building efforts. Limit your cardio to non lifting days, no more than twice a week and keep the sessions brief.
Never do cardio before lifting, you should conserve your energy for lifting.
If you want to have a low body fat percantage then it's all about what you eat and diet.
Hope this helped.
Tl;dr Do either cardio or lift but not both at the same time, it's not good to the muscles.

Could you elaborate on the body fat percentage please?

if you're trying to shed some pounds, a weight session before you do cardio will actually help you burn a lot more than if you just do cardio. just make sure you warm up first and don't jump right into any heavy lifting if you haven't done many workouts with weights.

Thanks for that bro

i wanna be like bigger but more defined.

Then IMO you should bulk first to get bigger and then cut to get more definition.

The thing is I think I'm already fat enough. Well not fat just I'm big enough but I don't have the muscle...

Then cut first and bulk later, from a leaner frame.

How do i work out during cutting?

I personally like a short (30mins) lifting session (4-day-split) and then a 15 minute High Intensity Interval Training workout.
