We did no pants /jocks while outside (while the weather was still warm). It started with a few hours a day and increased over the week. Then I started putting jocks on, took a few weeks, but overall very smooth! My LO was definitely ready tho! Hope that helps
We did the “bare bottomed” method. 3 full days without bottoms (no underwear, no pants). Look it up online you’ll see the full structure. Our daughter was fully potty trained within 2 days when she was 2 1/2.
