A great way to start to develop the hands is to do knuckle push ups and I'd also recommend using proper bag mitts on the heavy bag. Till date I've only ever used bag mitts for everything besides sparring - it makes all the difference.
These are my bag mitts:
I'd also recommend forearm/wrist exercises like wrist curls, forearm roller etc etc. Gradually build up resistance until you can do knuckle push ups on concrete and hit the heavy bag without damaging your knuckles or wrist. A lot of people jump from 0 to 100 and start hitting the heavy bag bare knuckle straight away - your more likely to injure yourself that way - at least that's what I've encountered.
Morio Higaonna (note he's been doing it for decades and built up to that - imho a bit too far but still to each their own) plus he's doing that in his 70's....:

Glad you posted that clip.
I was just saying the other day on a Go Ju sparring thread that they don't want to come at you with western sport fighting tactics. They want to grab you pull you in With Kumi Waza, club you with Atemi Waza, break your arms with Kensetu Waza and throw you away with basic Tachi Waza....Just like he's demonstrating in that clip. All of the Kensetu Waza are part of the Judo Nage No Kata curriculum that was borrowed from these foundational arts, developed for the Kodokan by Tomiki Sensei at the request of Kano Sensei to preserve those techniques in the Judo setting.
When David joined our Judo club, he already had years of that bone calcification training from Dan level Go Ju not even counting the 13 years of service in the USMC. It was an honor and a badge of survival to Randori with him for years and take his Shodan Nage No Kata Ukemi after the three months of training up to his test.
