tiger75:Then you could advice her ,after the cooldown, to go for another run with abs machines if her gym club has some.
Abs Machines? This is another very good example of why participants should NOT be dishing out advice as if they were a qualified professional. My friend I don't know what happens at the gyms where you train but in most modern places in the world now, machines that isolate your "abs" are about as old fashioned as leg warmers and headbands. For proper core work do some planks and all their variations and maybe some cable rotations. Yoga and Pilates or BB would also help. Do you need to do that after a pump class? Probably not.
As I said in a previous post - be careful about how you give advice, you are NOT qualified. And if that changes please do let us know so I can stop my ranting.
As to the original post, of recent releases 66 would have to be the hardest, no question.
