I guess this belongs to the bodybuilding forum but correct me if I'm wrong. So I decided to do ab wheel rollouts as an ab exercise and found out the gym doesn't have a wheel. I browsed the internet and came across two substitutes: The double dumbbell rollout and the barbell rollout. The latter seemed to be much more practical and I did it today.
Unfortunately though, as I was doing it, I felt almost nothing in my abs while my triceps were on fire, my rear delts were toasted and even my frikkin' neck hurt. I used the two 20 kg plates (and the two 5kg plates I used with the rows) on a barbell and that might just've been too high a leverage. So here's a video of me doing them: Correct me on what's wrong, thank you (otherwise fuck you).
