Optimal bodyweight

This is something I've been thinking a lot about lately. What is the ideal bodyweight for a person? What is the optimal weight for maximizing all the basic qualities one needs to function well in life? What is the correct strength to weight ratio for having some of all the strength qualities( limit strength,speed strength, strength speed,etc,starting strength,etc) and still having decent cv and muscular endurance as well as maintaining normal joint mobility and function?

I've spend so much of my athletic life either trying to gain or lose both body mass and muscle that I really dont know what my ideal weight is. I've been watching MMA athletes talk about getting down to fight at a certain weight ;" its my natural weight" they say.

natural weight training six hours a day or natural weight basically just living life?Training competitively for a sport changes everything.Or does it?

I was 135 lbs , 5'7" tall at 18 years old all the while eating anything that wasnt nailed down and training in competitive gymnastics 4-5 hours a day 5-6 days a week.I had great relative strength, low body fat, good power and starting strength and great mobility and quickness.
Actually this was probably me at my "crossfit"( for lack of a better term) best.

then I went lower to 125 as a marathon and ultra runner. too thin and very weak.
Up to almost 200 for bodybuilding and powerlifting.Lots of muscle but poor endurance,mobility,and limit strength as well.
One of my best bodyweights was at 154 lb. as a road cyclist riding 300-400 miles a week. this was a good weight. Had good leg strength( my calves have never been as good) endurance, power, speed agility,leaness and my upper body strenght and size maintained very easily;actually too easily as I was always carve it off so I could look like a real cyclist.

Just goes to show that whatever muscle is natural and easy to put on is hard to get off. Its the fake stuff, the muscle WE decide to add that seems to come off so easy.

Of course what you do always decides what happens physically. Grow up on a farm pitching hay and cranking on wrenches you will get very strong How big will be determined by genetics and how many calories you stuff in.

watching these fighters lately has made me re evaluate the strength to weight ratio thing as well as how to balance strength, mobility, endurance, etc.Of course I realize its all individual and will vary acording to goal. BUt I wonder what I would weigh if I grew up in a natural environment and ate according to appetite not a program design for gaining or losing mass?

Just like the less I eat the more I realize how little I really need, the lighter I get the more I realize that really functional( not necesarily sport) strength is more neurological than musclar and trying to alter that might be folly, in the long run. Of course competition changes everything;you mold the body to the will and the desire, and ego.

I am thinking more about what is "natural" and best for the long haul; now that I am an old guy and can ponder these things, :))

One thing is sure; the less need there is for limit strength the more that is left for training many more training qualities. the intensity is so high from overload training and the body stiffness required to lift truly heavy weights kind of squashes so many things out.

Movement is life. I'm so glad I can move again.Being really strong was fun, but this is better.I'm 160-163 now who knows where I will end up?
