There is no point in dropping your body fat. As i said before, you'll have a really hard time getting much lower because your pretty skinny already. Plus, if you lost any fat now, you would put it back on very very quickly when you started bulking.
-If you want to get bigger then stick to 10-12 reps.
-less exercises, 2per body part at the most.
-you dont need a whole day to work your abs, work them with 2exercises just like any other muscle.
-what about your legs and lower back?????? add squats and deadlift!
make sure you include the following at least once a week...
squat,
lunge,
deadlift,
pull ups (or lat pulldown),
chest press,
shoulder press,
bent row (or seated row)
core twisting exercise
core crunching exercise
If you are doing all this then you know you are working your whole body.
You dont need tricep and bicep exercises, you'll work them enough when you work your body, but add them in a few weeks if you feel you need to. but only one set of each at the end of a workout.
