I found a dylemma when I wanted to create a Minotaur or Centaur class. It seems they can get a Bonus in STR and CON, so if the strenght is the Natural Musculature of the character while the Constitution is the Natural Wealth and the Breezing skill, right ??

Then, if I raise the STR every 4 lvls, does it affect the Natural Weight of the character ( due to the new value applied there ), or it remains AS IS ??? I also have a problem when I was creating a Minotaur class: what is the Formula there ??  The Natural Height x the Bonus Height + the Bonus Weight ?? I don't understand it.

P.D. : someone should also explain me if there's a skill called Digging ( a hole, a ditch, etc etc ) and what ability it's related to.

Increasing your strength doesn't increase your characters weight per RAW because your weight is not affected by you strength score.

To determine your characters weight, you must first determine their height

1. Look up their Base Height (for example, humans start at 4'8")
2. Roll the specified dice for the Height Modifier (+2d10 for humans) and add that many inches to your characters height. Remember this number
3. Take the number you rolled in step 2, then multiply it by the result of your Weight Modifier (x 2d4 for humans)
4. Add the Height Modifier x Weight Modifier value to your Base Weight (110 lb for humans)

That's how you calculate weight (and height). Notice how it doesn't at all factor in strength.

Alternatively you can ignore all that and decide on your characters attributes.

Also, there's no digging skill. You don't need a skill to dig a hole. Your DM will decide the ability (if any) needed. 

But, if the Strenght is how much musculous you are, then it should apply a bonus on your Natural Weight. And, if you raise up this value every 4 lvls, then it's obvious the extra bonus you get, right ??

It's like in the REAL LIFE.... the more strenght you get, the more weighted you be.

5th edition D&D at least does not go into all of the fine details. Most of the time, a character's weight simply isn't important to anything mechanically. Grapples and the like are in broad categories based on size (small, medium, large, etc).

For digging, it would be an Athletics roll.

 Ok, so I guess it's the best time to buy a shovel and dig a ditch around every village I'll find. Hehehehe.... who knows.... perhaps i'll be rewarded by the local guards by applying an extra protection.
