Explosive movements are considered power training and generally creates both strength and endurance. If you try and move a weight fast as possible your muscles have to contract maximally basically.JFC: I like the extra crispy. Oh, sorry. That's KFC.
Mike Tyson: Is it true that Mike Tyson did very little strength training? I will admit it's been a LONG time since I've really thought about Mike Tyson. But I seem to recall he did a lot of cardio, some body weight exercises, and that's about it.
Physicality: Traits are what we're born with. Skills are what we learn. As my grandpa used to say, "You can teach a pig to climb a tree, but sometimes it's better to just get a squirrel."
Anger: Speaking just for me. I don't think it's all that helpful. In my experience, anger is often the outward expression of something else: inadequacy, frustration, sadness, depression, embarrassment, etc. When folks get angry, they are doing so because something else is actually going on. You fix that other thing and you'll be much happier.
You talk about traits but most people don't have the best knowledge, coaches, et cetera and think what they have "is the best" or "there's not much better so why bother". The psychology is more relevant than genetics. Everything in your DNA is expressed depending on factors outside of DNA. Epigenetics is a relevant topic here. Environmental factors, pressures, will affect your epigenetics and thus what DNA is expressed.
I mean what's the point you're trying to make about pigs and squirrels? It's severely conventional for people to give up and then rationalize it like you're doing, to just stick to less. It's not at all conventional for someone to actually FIGHT for something in any meaningful, high willpower way. Haha you're just saying **** those who don't even try say.
Anger: You're saying crap about "just give up" and "you can't achieve anything" yet talking to me about inadequacy. You gave up all the time and then got angry and then rationalized that anger is bad to completely shut down any attempt at "getting back into the ring". Don't project your twisted rationalizations mate. Your failures are a result of your own emotions and will. Nothing you say or do will change that
Frustration precedes either giving up or going harder and I can tell which you went with.
