To find out how much a 632-pound grizzly bear can lift, you would calculate 0.8 times its body weight:
\[ \text{Lifting capacity} = 0.8 \times 632 , \text{pounds} \]
\[ \text{Lifting capacity} = 505.6 , \text{pounds} \]
Therefore, you would expect a 632-pound grizzly bear to be able to lift approximately 505.6 pounds.
