With a character described that way, and with the stats to back up the description, there is no reason he should ever fail any average test of strength. Everything from shoving open a stuck door, to hoisting a keg onto his shoulder, should be things that are taken as a given part of narration. The same way a magic-user might cast a cantrip with a flick of the wrist, or how a ranger can ignore brambles and walk easily down the most treacherous forest path.
|Why the hell am I rolling for this?|
We call these shoelacing rolls, and they never, ever make your game better.
Rolling A Die Should Mean Something
Generally speaking, when you pick up your die, that means something. There's a chance you fumble your attack, and hit your enemy's shield instead of driving your blade into their heart. You might miss a slight hitch in someone's voice, tipping you that they aren't telling you the whole story. It's that knowledge that if you screw up trying to disable the device, you might set it off in your face.
Boiled-down, you shouldn't have to roll dice for things your character should understandably not fail at which have no real consequences. Otherwise you're just wasting everyone's time constantly calling for unnecessary rolls. If players get used to you making them literally roll every time they try to take an action, then pretty soon rolling to attack a pit fiend will feel a lot like rolling to dismount your horse without falling into a mud puddle.
|So, what's the alternative?|
If you haven't read the Chronicles of Darkness, there's a chart in the attributes section I would recommend reading, and re-reading. You find it near the Strength stat, and it specifically lists the amount of weight a character with a corresponding score can lift without a roll. You find a similar chart in the game Scion, where the Feat of Strength table lists what sorts of things are possible for characters whose raw physical power meets certain pre-determined levels (rip an unfortified door off its hinges, punch through concrete, stop a truck in its tracks, etc.).
While we may not have a corresponding chart for many D20 games (EDIT: My mistake, we totally do. As a commenter pointed out, the Carrying Capacity chart lists what a character can lift and carry, and how difficult it is, based on their Strength scores. In Pathfinder, you find the chart on page 171 of the Core Rulebook), I'd recommend taking the time to absorb the spirit of those charts into your DM mindset. In short, set benchmarks in your mind for what levels of skill, and what raw attributes, render certain challenges a given. Because while Khantos might be able to easily hoist a 400-pound chest onto his shoulder without a problem, his Dexterity is nowhere near as extraordinary. So while he'll get a pass for certain feats of Strength, he will have to make the same Dexterity checks as anyone else with his score.
With that said, though, he can probably tie his shoes without having to roll a DC 5.
What Are The Consequences of Failure?
Some folks are, no doubt, contemplating leaving acidic comments along the lines of, "Well, why shouldn't dragons just automatically hit the party members, since they have such high stats? Wouldn't those rolls be pointless, too, by your logic?" So, in order to nip that in the bud, I will point out the central pillar of this piece of DMing advice.
If the consequences of a roll wouldn't matter (or they would exist only to undercut a player), then don't bother with the roll.
|Dice don't make inconsequential things important.|
For example, let's go back to Khantos. Sure, it's no big deal for him to lift heavy burdens, and carry them into the inn, or to haul them out of a dungeon where there are no traps, and no one is shooting at him. The reason you shouldn't ask for a roll in those situations is because if the player fails it, nothing of consequence happens. All you're going to do is undercut the presentation of character who is effortlessly strong by making him fumble a task meant to give an impression of just how muscular those thews are.
Now, say that Khantos wants to smash an enemy's rib cage in with the huge maul he just picked up. Yes, Khantos is still just as big and powerful, but now there's a consequence to his failure (that consequence being that another character doesn't get his chest cavity pulped, and may survive to riposte and stab Khantos in the throat). So, while that huge Strength score makes it more likely that he'll strike true, he still has to make the roll because the consequence of failure matters in this instance. The same is true if Khantos is climbing a rope, and wants to catch someone falling past him. Yes, his powerful physique means he could normally just pick that person up and fireman carry them, but if you catch them while climbing there's a chance you both fall. So in that circumstance, you require a roll.
At the end of the day, ask why you want the players to make specific rolls. Because we already make a lot of rolls in any given campaign. We don't need to make them to get out of bed, sharpen our swords, or put on our armor so we can go start doing things that actually matter.
