One of the most common ways that disability applicants qualify for benefits is by having functional limitations in their residual functional capacity that rule out all jobs. Functional limitations are restrictions you have in performing activities that result from a long-term medical condition. These restrictions are incorporated into your residual functional capacity (RFC), which is Social Security’s assessment of the most you’re able to do, physically and mentally, in a work environment.
Depending on your specific medical conditions, your RFC may contain both exertional and non-exertional limitations. The more limitations you have in your RFC, the easier it will be to convince Social Security that you can’t do any full-time jobs, so it’s important to learn how these different types of limitations interact with each other to eliminate your past (and any other) work.
Exertional limitations are strength-related restrictions on your ability to work full-time. (20 C.F.R. §404.1569a(b), §416.969a(b) (2026).) Specifically, exertional limitations affect how you can perform the following tasks:
For claimants with physical conditions, exertional limitations are the foundation of their RFC. The Social Security Administration (SSA) uses your exertional limitations to decide what types of physically demanding jobs you can do. The agency classifies all jobs according to the following five exertional levels:
If you can perform work at a particular exertional level, the SSA assumes that you can work at all less strenuous exertional levels as well. For example, if your doctor says that you can’t lift more than 20 pounds due to a shoulder injury, the agency will give you an RFC for light work. So if you never lifted more than ten pounds at your old work (a sedentary job), the agency will find that you can return to your past jobs—because they’re at a lower exertional level than your current RFC. You’ll need to have additional, non-exertional limitations to rule out your past work.
Non-exertional limitations are restrictions in your RFC that aren’t strength-related, but still affect your ability to work. (20 C.F.R. §404.1569a(c), §416.969a(b)(2026).) Examples of non-exertional limitations include:
Non-exertional limitations can be caused by physical symptoms, such as carpal tunnel syndrome, or as a result of mental disorders, like anxiety or depression.
Keep in mind that the SSA needs to see medical documentation of every limitation, both non-exertional and exertional, in order for those limitations to become a part of your RFC, so make sure you provide the agency with all your medical evidence.
Getting benefits based only on exertional limitations can be difficult because the SSA usually finds plenty of jobs that you can do within a specific exertional level. If you’re limited to light work and don’t have any additional limitations, for example, Social Security is likely to find that you can work as a cashier—a job title with over a million positions nationwide.
However, it’s rare that a disability claimant won’t have any non-exertional limitations in their RFC. The agency is required to consider the combined effect of your limitations when determining whether you’re disabled (20 C.F.R. § 404.1545(e), §416.945(e) (2026)), which includes symptoms such as chronic pain that can have a significant impact on your ability to reach, bend, and concentrate.
Under Social Security’s five-step sequential evaluation process, the agency needs to agree that you can’t perform your past relevant work before determining whether you can do any other jobs. (20 C.F.R. §404.1520, §416.920 (2026).)
The SSA classifies your past work according to exertional level and skill level. (20 C.F.R. §404.1568, § 416.968 (2026).) If your past work is at the same exertional level as your current RFC, but you have additional non-exertional limitations that keep you from doing your job, you can use those non-exertional limitations to rule out your past work.
In the above example, even though the claimant’s exertional limitations didn’t rule out her past work, when her non-exertional limitations were considered, the SSA determined that she couldn’t do her old job. Depending on your age, education, and whether you have any transferable skills, ruling out your past jobs could be enough to get disability benefits under the medical-vocational grid rules.
Another way that you can combine exertional and non-exertional limitations to qualify for benefits is by showing that your limitations, in total, prevent you from performing any jobs. For claimants under the age of 50, this is by far the most common way of getting approved for benefits.
Mental limitations, for example, are frequently combined with exertional limitations to rule out all work. Because even the easiest, least physically demanding jobs still require you to show up and complete your duties on time, if you have mental limitations that reduce your productivity below what employers will tolerate, the SSA will find that you can’t do any work.
Other non-exertional limitations that can rule out all jobs can include:
In Social Security lingo, such limitations “erode the occupational base” to the extent that they are “inconsistent with competitive employment.” (For more information, see our articles on getting disability by arguing that you can’t even do a sedentary job and what happens if you’re unable to work for medical reasons.)
Most disability claimants who get benefits win their case after a hearing with an administrative law judge. But having a successful hearing means you’ll need to know how to answer the judge’s questions and cross-examine the vocational expert helping the judge decide whether you can work.
Consider hiring an experienced disability attorney to help you through the disability determination process. Your lawyer can gather medical evidence supporting your limitations, ask your doctor for a useful opinion statement, submit a pre-hearing brief on your behalf, and represent you at a hearing. Most attorneys offer free consultations, so don’t hesitate to ask around in order to find a lawyer who you feel comfortable working with.
