Sit tall, tap those toes, keep the core ticking.
Keep the lean steady and let your lower abs do the lifting, not momentum.
Leaning back with your feet off the floor puts your core in charge of holding the whole position, and every toe tap forces it to control a leg lowering away from your centre. The abs work isometrically to keep the lean steady while the lower portion resists each tap, which is a lot of value from a move that needs zero equipment. It is a smart entry point before harder leg-lowering work.
Yes, it is one of the friendlier core moves because you control the lean and only one leg lowers at a time. Keep your chest tall, tap lightly, and stop the set when your lower back wants to round.
Far enough that your abs switch on to hold you there, but not so far that you collapse or your back rounds. A modest lean with steady control beats a deep lean with shaking and momentum.
Slow the taps down, tap further away from you, or straighten the leg as it lowers. Extending the leg lengthens the lever dramatically, so add that only once the bent-knee version is genuinely easy.
