Magento 2 basic installation have three ‘offline’ shipping methods included: free shipping, flat rate and table rates.
They are called ‘offline’ because all shipping rates will be calculated using offline resources, basically only ‘table rates’ use advanced math and calculate fee according to provided CSV file.
Magento 2 also comes with four more shipping methods, dimensional weight methods (DHL, FedEx, UPS, USPS), that use external data to calculate how much customers have to pay for shipping.
Most popular ‘offline’ shipping method among customers is ‘free shipping’, everybody loves free shipping, they will pay just for products and there is no extra fee – great right 🙂

So his request was quite simple, to limit free shipping option to 120 lbs. of total cart weight, if items in cart go above that value ‘free shipping’ shouldn’t be available.

Instead copying parts of code and explaining every line I decided to provide module as package (please backup everything before deploy it) and I am quite sure that you will manage to grasp code in it.
Unpack archive into your Magento 2 installation root folder, navigate to /bin folder or use path in command line (as you like) and run commands in console:
magento module:enable Smdesign_FreeShipping

I am new to Magento 2 but eager to learn it and hope that will be able to post about it often.
