Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
Parker went to the gym and found 4 twenty pounds dumbbells set up for weightlifting. He added two more dumbbells to the setup and started his exercises. How many pounds of dumbbells is Parker using for his exercises?

### Response:
4 twenty-pound dumbbells weigh 4*20 = <<4*20=80>>80 pounds.
When Parker added two more dumbbells to the setup, he increased the weight by 2*20 = <<2*20=40>>40 pounds.
He, therefore, used 40+80 = <<40+80=120>>120 pounds of dumbbells for his exercise.
#### 120
