just started watching season 1 and have a question..

No, he is very strong and he is hard to injure, but the hulks strength level is considerably higher and he gets stronger as his anger increases.

In the comics Luke Cage is only about as strong as Spider-Man (lifts about 10 tons). His real power is his super tough/dense tissue structure which makes him practically indestructible. It also makes him very heavy. I believe one source said about 450 pounds.
