Train with Iron Man…’s head.
Tony Stark always combines functionality, durability and style into everything he does. With that in mind, the Marvel Hero Elite Iron Man Kettlebell appears to have been sculpted by Mr. Stark himself. 40 lbs of muscle building, mobility increasing awesomeness. Made of iron (unlike Iron Man) and encased in a chip-resistant coating, they are made to last. They will not increase your chances of becoming a superhero, but then again, they might.
