I’m certainly not one of the big experts around here with 20 years experience, but you might try doing total body 3x a week. Total body seems to work best for most beginners, or a upper and lower split. 5x a week for a newbie seems a bit much. Also how are you lifting? Is it explosive on the up part of the lift, and do you resist and control the weight on the way down? Whats your intensity like? You’ve listed what your maxes are but not what your routine is, the weight your lifting and how many reps/sets etc. Some people respond to high volumes better, some people respond to less volume but more intensity. The bottom line is, if you’re doing what your buds are doing and its not working, then do something else. Thats the golden rule of lifting right there, if it aint working, do something else.
All in all though, its hard to help anyone unless you give us specific details. As far as diet goes, you might be getting fatter, simply because you’re eating alot, but not lifting in a way to build muscle, so those calories are just getting turned to fat. Follow the advice of many on this site, and time your carbs in the morning and around your workouts. the rest of the time just eat meat and green veggies. And if you can, buy some Surge and creatine, cuz they roxorz and stuff lol. Also, are you getting plenty of sleep? Many variables that could be messing you up, the devil’s in the details.
