ADL means Activities of Daily Living. The SSA and the judge that may eventually hear your case always asks you what you do during the course of your day. I always prepare my clients in advance for this question. Finally, I like to deep dive into one question but I also want supporting medical documents that agree with what you say about your ADL's.
For instance, if you cannot stand for more than an hour or so continuously, the judge will want to know why. Can you walk, sit and stand for 6 to 7 hours a day? Does pain interfere with your ability to function? How do you relieve the pain? Do you need to lay down and if so, for how long?
In the questionnaire I ask your doctor to complete, I do ask about whether your pain complaints are credible, whether your pain would require you to lay down and whether your pain will cause you to have good and bad days if you were working. How many days a month or a week would your doctor expect you to be out of work due to your current pain level. Does this match what you are testifying to as well?
These are not little matters. This correlative testimony adds or detracts from your credibility when testifying about ADL's. You need to go over this information with your lawyer long before you attend a hearing.
