Done with barbells ups the level of hardness
Things to feel: Knees slightly bent, feel the heels more than the toes, no swaying, spine is straight, chest is lifted. The move is awesome!
+ Abs are full and tight, inhale on the way down and exhale on the way up,
+ Bar doesn't drop below the chin!!!
+ Elbows do not lock out, ever!!!! The move will feel short in length, that is fine, the range is short for biomechanical efficiency
+Watch out for the head and nose on the way down, the head will back out of the way, keep chin tucked, no looking up.
2-3 sets of 15-20 rep
