While there are varied schools of thought on this approach (some of which say I'm mad), this way of training my core has really worked for me and enabled me to get some pretty good results. I've never been afraid to show off my core (even when I was super lean with little musculature) but changing how I think about training my core has really allowed me to get some more muscle in this area (combined with a super solid diet of course)
So while my diet has had the most impact on how my core looks, I'm quite happy to share my core workout.
I do this twice a week, takes me about an hour for the whole workout so perfect for a lunchtime training. This is what I train and I've been doing this a while, so for anyone just starting out, drop the weights right down, lower the reps by half and work your way up to these. I started doing most of the weighted stuff here at just body weight and I've increased the reps steadily as I've found it getting too easy. I do everything in this order and I don't rest between sets, I just move on to the next exercise straight away. Also if something hurts (like actually hurts not just "ow my muscles hurt") I adjust the workout to suit. I always listen to what my body says. Like in my last core workout hanging knee raises hurt my bicep, so I left them out for the workout.
So remember if you're just starting out -halve the weight (or drop it altogether) and the reps for all of these!
