How much logic is “right” to put in Callable?

Question

I often use calls, and I was concerned about a question that annoys me:

Suppose that to run the foo () function, you first need to perform a couple of checks.

If you 1. Insert checks as part of the called:

class A implements Callable<Long> {
...
public Long call() {
    check1();
    check2();
    return (run()); 
}

2. OR, paste all this logic into another class (ALOGIC) and use Callable for shell only for shell? class A implements Callable {
...
public Long call() {
ALogic aLogic = new ALogic();
return (aLogic.run());
}

What do you think pro and con are? What do you usually prefer?
