Hey everyone, first time poster here
Wondering if anyone had any suggestions for a good beginner - intermediate workout routine?
I'm more focused on staying lean (which I know has a lot to do with diet) than gaining a lot of muscle mass but would still like to build a decent amount.
Currently 6'1 about 185 lbs
I goto the gym about 3x a week but mainly do a basic exercises to stay fit (cardio, bike, weight training etc) and try to hit all muscle groups when I go but I don't follow any routine and I'm rarely sore the next day
Anyone know if I would benefit from following a small-medium intensity workout routine? (Would like to stay at 3-4x per week as I have a lot of class/studying etc)
+ Gym is a 3 minute walk from where I am which is nice
Lmk guys

any help is appreciated
