This is not a story about steroids. But it is about improving your abilities on the playing field. Using technology as sophisticated as any developed in traditional fields of science, athletics companies have designed this equipment to make you better, stronger, faster and healthier. It’s funded by absurd amounts of money and validated by the best athletes in the world. And if you’re lucky, it will be sitting in your gym bag soon.

Get ready to add a few more golf clubs to the bag – sort of. Callaway Golf launched its new I-MIX drivers this month which allows enterprising duffers everywhere to swap out specific heads and shafts according to course or weather conditions, or just to impress their cronies. The heads are attached to the shaft using a custom torque wrench that provides an audible click and a visual indicator suggesting when it’s safe to let the big dog bite.
