Seven-minute planks are challenging enough, but abs wheel planks take the bodyweight core exercise to a whole new level of ouch. I dedicated seven minutes each day for one week to see what, if anything, would happen.
Of course, I’m not talking about physiological changes to how my body looks — spoiler, no sculpted six-pack or chiseled torso is waiting at the finish line just because I upped the ante on planks. Sadly.
