How do I strengthen my core as a complete beginner?

Start with the basics: planks, dead bugs, and bird dogs. For planks, hold a straight position on your forearms and toes for 10-30 seconds, rest, and repeat 3 times. Dead bugs involve lying on your back, extending opposite arm and leg while keeping your lower back pressed to the floor. Bird dogs are similar but done on all fours. These exercises are safe, effective, and teach you to brace your core properly without straining your back. Do this routine 3 times per week, focusing on controlled breathing and good form rather than speed or duration. Progress gradually by increasing hold times or reps every week or two. Consistency matters more than intensity at this stage.
