I have back problems and need to work on my posture, one element is the lower ab to 'pull' my lower back into a more upright position (I tend to fall into a hollow back).
When I ask about activation, I mean this: get the relevant muscles to stay tense and active for a long time after the workout so that my posture stays OK with less conscious effort. What is a training modality or exercise to achieve this effect?
I'm mostly looking at planks and kneeling ab-wheel rollouts as exercises that have, I think, a more max-strength focus for me but I also occasionally do exercises with a stronger strength-endurance focus.
Should I prioritize one over the other to achieve muscle activation?
(I've asked this on fitness but it may be appropriate here, too)
