so I'm 16 and I kind of have a home gym which has a row machine, a bar (which isn't the right weight its like a 5kg bar or something) I have some 5 and 10kg plates for the bar, I have a pull bar, kettle bells, a bench and an adjustable bench. I also have a squat rack but the bar is too small for the rack. I am just beginning to use the gym/ weight lifting but I'm not sure what exercises I should be doing and what muscle groups I should be focusing on different days. I would be amazing if people could link a program or something, or just give me recommendations of what to do. Also not sure if this will help but I'm fairly skinny and I weight about 50kg
