Today, the 5th slam ball ends at chest-level and is propelled as far as possible (using an offset stance as in our medicine ball throw) and chased immediately.
Today, dumbbell or kettlebell is held directly over chest. Work to “True” failure (loss of physical positioning) not “Relative” failure (loss of mental endurance).
Airplane push-up- plyometric or otherwise- simply begins and end with chest/ hips on the ground and hands off the ground; Maintain tension and position, and move with intent.
