To be clear, when I said "I highly doubt either of us will have much success with either endeavour." I meant in terms of fixing the above issue (if you even have it, I don't know), not in terms of training progress overall.@BigShoes how about this, you try narrowing your hips, I'll try building my core. Let's check back in a year or so and see whose progress is more impactful. Science at its best :)
You can certainly build a very strong core in a year's worth of training - it's a very worth goal that I have no doubt you can achieve.
