There's a principle in weight lifting revolving around specialization. Basically it says "The more you train your muscles to do what you actually need them to do, the more transference your training will lead into performance." Example: if you're a football player, you should have a different squat technique than a basketball player because you start your explosiveness from a different position.

If I wanted to work on grip strength, I'd be doing farmer's walks, deadlifts, and shrugs.
