Fingertip/knuckle push-ups, towel pull-ups, and farmer's walks aren't what I'd consider a way to primarily train the hands/wrists/feet/ankles. They're variations of basic exercises that emphasize the grip in addition to their regularly targeted muscles, comparable to using a fat barbell for any given barbell exercise. Farmer's walks are a different beast in that it's one of the few exercises that basically targets everything from the feet to the traps in a dynamic way.
The case could be made that hand/finger extension (rubber bands around fingertips) is more important for wrist health than training flexion (paper crumpling, rice digging, etc.) because a martial artist spends more time in a closed fist position already. Finger/wrist extension can also play a role in maintaining elbow health.
And even though it's popular with bodybuilders, when pointing the feet in or out during calf/toe raises, you run the risk of increased stress on the joint's support structures with minimal benefit to strength or muscle. Not worth it at all.
Anyhow, it's difficult to discuss/explain the use of any group of exercises without knowing the context they're being used in (what the rest of the weekly training plan looks like).
Them's the breaks, my man. It's why we train for decades, not months. Trial and error, and learning as you go, is a huge part of a lifter's life.
A hypertonic muscle could be a simple case of impaired mobility. I'd say some dedicated mobility work is essential for any athlete, which should cut off some problems before they get to be real problems. But again, it's hard to "correct" an issue without knowing the full context of the training program.
I appreciate the compliment, but I very much don't belong in the same sentence as those guys.
Checking post history to see what I've written previously? That's my trick. Ha. But um... ... that thread was from 2009. Show me a coach who trains people the exact same way after 4 years, and I'll either show you someone who's at the absolute pinnacle of their career because he's figured it all out or I'll show you someone who's an absolute doofus.
It's safe to say that my current professional opinion is that it's more important to consider every exercise as a potential ingredient and combine the appropriate ingredients in the appropriate amounts to achieve the desired result. Blanket statements like "athletes should rarely do isolation exercises" is as silly as saying "bodybuilders should always train to muscular failure to stimulate growth."
I'm not going to debate, counter, or concur with what another coach says because everyone has different methods.
A main goal would be, by literal definition, one thing and not three. Trying to prioritize three separate tasks will results in slow, inefficient overall progress at best, and a circular state of non-progress at worst.
Don't cave in to the urge to try achieving all things now-now-now-now.
Unless you have a history of small joint injuries, you should get plenty of "accidental" work with free weight-based training and bag/pad work. "Prehab" work (mobility drills, tissue quality work, and other joint health measures) will also work towards this.
Alwyn Cosgrove and Charles Staley have put out some great info on the topic. A few UFC fighters have trained at Mike Boyle's gym. I don't remember him putting out a fighter-specific program, but I'd bet it adheres to his general programming ideas.
Chad Waterbury is the S+C coach for a Gracie dojo and he had several articles about training fighters:
Dan John's "Armor Building" article is interesting and could be useful in the short-term:
Also, head over to the Combat forum right here. Tons of guys (a lot of them are competitors) have good info.
For sure no problem, Bull.
