Dynamic Strength
Ability · O*NET work requirement
The ability to exert muscle force repeatedly or continuously over time. This involves muscular endurance and resistance to muscle fatigue.
In the O*NET occupational database, Dynamic Strength is an ability that work requires. O*NET rates how important it is (1–5) and what level of it a job needs (0–7) for every U.S. occupation. It is rated as important (3 or higher) in 40 of 894 occupations.
Breadth here means how widely O*NET rates this ability as important across occupations — not that it is rare, high-paying, or currently in employer demand.
Occupations that rely most on Dynamic Strength
Ranked by O*NET importance to the occupation (1–5). Bars are sized against the 1–5 scale; the level column is what depth of the ability the job needs (0–7).
How AI is used by roles that need Dynamic Strength
This ability is not itself "being automated" — but we can look at the roles for which O*NET rates it important and ask how those people actually use AI. This rolls the Anthropic Economic Index per-role signal up across those roles (importance-weighted). 27.5% of the 40 roles where this is important carry observed AI-usage data (11 roles).
Across those roles, 50.9% of AI conversations are people working with AI and 16.2% hand a task to AI , with an average autonomy of 3.87 / 5.
| Collaboration pattern | Share | What it means |
|---|---|---|
| learning | 38.3% | you ask AI to explain or teach |
| directive | 15.7% | AI does it; you give the instruction |
| task iteration | 12.3% | you and AI go back and forth |
| feedback loop | 0.5% | AI does it, then adjusts from your feedback |
| validation | 0.4% | you do it; AI checks your work |
Roles behind this signal
The roles where this ability is most important and that also have the most AEI data. "Works with AI" is the role's share of conversations that augment rather than automate.

| Correctional Officers and Jailers | 3.0 | 52.7% | 3.0/5 |
| Choreographers | 3.8 | 54.5% | 4.0/5 |

Source: Anthropic Economic Index (2026-01-15-v4-plus-2025-03-27-v2) over a sample of Claude.ai Free and Pro conversations — not all AI tools and not the whole workforce. Shares are of observed conversations, weighted by how important this ability is to each role; some conversations are left unclassified by Anthropic's taxonomy, so shares need not sum to 100.
Industries that concentrate this
Where Dynamic Strength matters most across the economy. Employment reach is the share of an industry's workers in occupations that significantly rely on Dynamic Strength (O*NET importance ≥ 3 of 5). Concentration compares that reach to the national average industry, so a value above 1× means the requirement is more pervasive here than across the economy as a whole.
Nationally, about 1.8% of workers are in occupations that significantly rely on Dynamic Strength (measured across 52 industries).
Sectors with the most such workers
| Sector | Workers | Employment reach |
|---|---|---|
| Construction | 1,313,140 | 16.2% |

| Arts, Entertainment, and Recreation | 232,340 | 8.8% |
| Agriculture, Forestry, Fishing and Hunting | 198,100 | 46.8% |
| Administrative and Support and Waste Management and Remediation Services | 174,620 | 1.9% |
| Other Services (except Public Administration) | 132,340 | 3.0% |
| Health Care and Social Assistance | 95,170 | 0.4% |
| Educational Services | 36,500 | 0.3% |
| Retail Trade | 35,870 | 0.2% |
| Wholesale Trade | 34,970 | 0.6% |
| Transportation and Warehousing | 21,010 | 0.3% |

Reach is a measure of how widespread a requirement is across an industry's workforce, not how intensively any individual uses it. Sector worker counts come from BLS OEWS employment; the significance threshold and tool use come from O*NET. Industries shown by concentration are filtered to a real worker base so a tiny specialty cannot top the list on rounding.
