Your quadriceps femoris are generally in a state of partial or full contraction if the leg is completely or somewhat straight.
The answer is absolutely "did surprisingly well." "Good" is used to describe a state of being, where "well" is used to describe a state of action. For example, the answer to the question, "How are you?" is "Good," because you are good, and "am" is a state of being. The answer to the question, "How are you doing?", though, would be "Well," because you are doing well, a state of action.
Use "is being" when the subject is singular (he is being, it is being) and "are being" when the subject is plural (they are being, we are being). Both forms are used to describe actions that are happening at the moment or in a temporary state.
The quadriceps femoris are naturally in a state of partial or full contraction if the leg is completely or somewhat straight.
