I still live in my parents house (im a teen dont come for me) and right now our set up consists of a tread mill, dumbells going up to 45 pbs, a bench press, a squat rack, a ez bar, and mats and stuff for body weight workouts. If i want to decently increase my muscle mass (I am 17, 155 lbs, and 6'4) is it possible for me to do it with what I have in my current home gym? Im not 100% opposed to going to an actual gym but money is tight and I am kinda anxious doing physical activity around others. Ive always been self-conscious about my appearance and I think I would go insane if I went to the gym atleast at my beginner level. Let me know your thoughts
