(age 11)

Tim is only 11 in these pictures, but look how muscular his calves are!

Here, Tim is working out in his backyard: running, jumping a 2-foot wastebasket and then doing plyo jumps. What's remarkable about the jump pictures is the great capture of his calf definition at that age. You can see the hard muscular ridges of his calves and the vascularity on them. You can also see his Achilles tendons stand away from his leg as his muscles put tremendous force on them.
