Jesus christ. You need a reality check.
Looks like u gained half fat/half muscle. If u cut now, youll most likely end up exactly where u were now. Skinny with some abs, congratulations, youll look exactly like 95% of kids your age.
Keep the milk but only for when u wake up, pre and post workout.
Eat meat, nuts, vegies, whey shakes and evoo if u wanna lean out a bit. We're all different, if u cant handle not seeing ur abs, delete the milk all together.
You also have to make sure the scales continue to climb, if their not, eat more, keep track of what your eating. Not gaining? Eat more than you did.
For your routine, try maybe an upper/lower split, instead of total body.
Make sure all your lifts are increasing every time you enter the gym. If ur not, eat more, rest more, train harder. Still not? Eat more.
Keep it simple. Be consistent.
Its a marathon, not a sprint.
Try doing this fast, youll get fat. Find a pace at which ur body is gaining but not gaining too much fat. BUT still remember fat gained be burned quick. muscle takes years to create.
Good luck .
