I am not afraid to admit some of my workout sessions are extreme! especially my leg days to the point that now they are no longer fun. My legs have developed a lot, I am seeing muscles in places where I didn't even know existed. There's no need for me to train my legs for 2 hours but I do it, some movements are less challenging and others are very challenging let me explain...
in total you only need 45-60 minutes to train legs but because I am a psycho who loves to torture myself at times I do it for 2 hours! I normally train like that on Saturday mornings. It's brutal I lift heavy, I sweat a lot, I lose my breath, and I feel exhausted by the end of it. I don't workout like that more than once a week because it is not sustainable and I would suffer from muscle fatigue. Now that I started taking creatine I have even more stamina to keep going harder in the gym. When I work out like a maniac I don't do it for muscle growth I do it for my mental health. I need a hard session at least twice a week... I also go hard on Thursday for my back days too. I need a great session to feel good and to want to keep on living a happy life. I am not even sure whether or not my anti depressant medication is working anymore but all I know is the gym is keeping me alive and I need it desperately. I could be crying in the gym parking lot and after a workout I am laughing like an idiot...I all I need is 2 hours in the gym, just give me that and I am the happiest girl in the world. Why Do you think I work out 6 days a week? I don't need to workout this much! I do it for my mental health as well as a nice body.
I am happy with my results and we're only getting better and better :)
