bro your weight will come with time especially if you have only been lifting for 2 months. stick to the basics for now. heres an example:
chest:
flat bench
incline bench
decline bench
flyes
Back:
lat pulls
seated rows
bent over rows
t bar
arms
ez bar curls super set with skull crushers
standing dumbel curls with tricep extensions
preacher curls with milllitary dips
concentration curls
shoulders
side raises
bent over rears
front raises
millitary presses
upright rows
shrugs
legs
squats
incline sled
horizontal sled
leg ext
many others you can do to.
hope this helps a little bit. i am a 220lbs guy and doing this things give me a great tear down and rebuild bro. just eat big lift big and sleep big.
also are u taking any protein shakes or anything like that?
as far as your reps go bro try to stick to 8-10 maybe 12 at most. just my 2 cents.
