Question

“I’ve never weighed or weighted over 120 pounds.” ?

Answer 1

Answer:

Weighed

Explanation:

I would say weighed is the best bet b/c we use it to to talk about when measuring weights. Like, this package of chocodiles weighs about 1 lbs (We don't say weights around).

Weigh is typically used as verb (as in your case and my example) and Weight is typically used as a noun (like the weight of this machine is 2000 lbs.)

Weight can also be used as a verb but its meaning will be different. When using it as verb, it means to put importance to something or put heavy object on top of something.
