Tom originally was only able to lift 80  kg farmer handles per hand.  After some training, he was able to double this number.  He then decided to specialize and was able to get an extra 10%.  How much weight can he hold in total?
After doubling he was able to hold 80*2=<<80*2=160>>160 kg per hand
Specialization gave him another 160*.1=<<160*.1=16>>16 kg
So he lifted 160+16=<<160+16=176>>176 kg per hand
That means he lifted a total of 352 kg
