bro, try adding in more cardio into your daily workout....and reduce carbs and start eating clean....for the exercises try going for some compound exercises ....maybe something like

Barbell Squats - 12 , 10 , 8 REPS and 3 Sets
Bench Press - 12 , 10 , 8 REPS and 3 Sets
Barbell Shoulder Press - Same as above just add a drop set.
Deadlifts - 8 , 8 , 8 (try heavy enough just so u can hit 8 reps)

..then thats all for the day...go to the gym next day and hit abs.

yeah....depending on what your targets are whey protein is a supporting supplements...if you're trying to bulk...whey is just a small portion of the calories, proteins, and carbs, you still have to get the rest from food...and it's kinda the same for cutting down, only have to reduce the calories, proteins and carbs down.

to be honest..i personally think you can only choose a target at a time...either bulk or cut...if you're gonna bulk u have to eat like you've never eaten before..of course clean calories...and if you're gonna cut....reduce stuffs down just enough to lose fat and not let your body go into catabolism.
