But in his calves defence I can say, that these muscles are extremely hard to train or make big. Simply take a look on top bodybuilders. Everyone have huge back, huge shoulders, arms, quadriceps, but not everyone have huge calves. So it is genetical.
Everything relating to the body is genetic to a large degree, but calves are actually quite easy to train (meaning to increase their strength), they might be harder to grow, but I don't think you'll find any pro-bodybuilder without properly sized calves.
For the most of amateur athletes, they'll be on the very bottom in terms of priorities. Personally, I haven't done any calves-isolated exercise in a very long while.
Yup and he's gonna face either of those guys at some point in the future anyway... It's just when he's back he'll skip Stipe Miocic. But the thing is at Jones' age, recovery and rehab after the surgery could take longer than anticipated. And even if he does return at the anticipated time, his knee could continue to bother him. He'll prolly have one or two more fights in him then call it quits.
I have my doubts if Jones will be eager to fight either Pavlovich or Aspinall. He was going after Stipe only because Stipe was considered to be the best heavyweight in terms of the most wins in title bouts. In the past he also mentioned that he was only after big money fights, and I'm not sure if a fight against Pavlo/Aspinall would sell that great.
I wouldn't be very surprised if Jones announced his retirement anytime soon. I hope that won't happen though.
