This is just in: You do not have to be a torn Adonis with a perfect six pack, ostrich egg biceps and oak legs to be sporty and strong. And you definitely do not need the body of a Greek god.
Your last proof: Andy Ruiz Jr., the WBA heavyweight champion you've never seen before. Just in case you missed it somehow, Ruiz defeated defending champion and Greek God Anthony Joshua last weekend – a victory that upsets the mindset of sports fans everywhere.
You see, sports fans love to mistake "fitness" and "athleticism," but the two things are not one and the same. Joshua is "fit" as Ruiz, muscled on muscles and torn abdominal muscles, an eternal champion of underwear Olympics. Ruiz had gained 268 pounds before the party after the fight, none of it was chiseled. And before the fight he called himself a "little fat boy".
However, Ruiz is champion for one reason: his skills are perfect for his sport. The big guy can throw a punch and take a hit. Boxing is about the art of punching and absorbing hits. No one has ever won a Pro Sport title for his size 29 waist.
Sports are about abilities, and these skills do not always correlate directly with body fat percentage or VO2 max. We have not learned that yet. That's why Twitter is still the fat Ruiz, even though he's the latest elite professional carved out of dough rather than granite. There's Yankees pitcher CC Sabathia and there was Shaquille O'Neal before and (Spoiler Alert!), When NFL Defensive Tackles get by without a shirt, most of them do not flash six-pack.
All these big boys do exactly what all top athletes do: Practice improving their actual games. Sure, you can build a bigger, stronger chassis for your sport in the gym, but this chassis still needs to know how to work for their sport. And this can only be learned in the weight room, unless your sport is CrossFit.
For any other sport you have to spend a lot of time on the actual playing field, which is why Steph Curry spends his days lifting three pointers instead of dumbbells, and Antonio Brown catches low-season passes instead of bolstering his bench press. There is also a current fitness principle for this: specificity of the training. Essentially, you are improving the things you train to improve.
It just so happens that you get chiseled abdominal muscles and muscular arms in many sports while you train for it. Cyclists and sprinters must be as low in fat as possible so that they can gain less weight while moving. Basketball players jump higher with fewer pounds, and the best base stealers in baseball do not play for the fat of a kettlebell.
