Hello everyone, I am in need of some really advanced dynamic ab exercises. I am looking for dynamic ones as part of the reason because they simply build more muscle mass and that is one of my major goals at this point. I really have a solid core at the moment - dragon flags are way too easy..., I do weighted hanging leg raises with 20kg, decline sit ups with 50kg (and I simply can't hold any more weight this way) and I am able to perform 9 full ab wheel reps (if I push myself I can definitely do even more). So can you please advise me on how to make my ab training even harder ? As I said I am looking for dynamic ab exercises, not static ones. And I would prefer them to only work the abs since I really feel exhausted at that point of the workout. Thank you in advance !
