What it is: Floor Flopping
Why it is sick: It means you just worked your ass off. A set of Floor Flops is a surefire way to know that you just gave your training session everything you had in you. Generally, Floor Flops are preceded by a lower body compound exercise or a total body exercise (squats, deadlifts, cleans/snatches, sled pushes, sprinting, etc). We sure aren't talking about leg extensions and bicep curls here, folks. It is pretty rare, but possible I suppose, to induce Floor Flops from upper body work; maybe push presses. The best cues to remember when doing the Floor Flop? Make sure you stay away from moving parts; try to stay out of peoples way; stay down until the room stops spinning; if you end up puking, you have to clean it up yourself.
As a precaution, don't force the Floor Flop. You don't wanna be "that guy". You'll know when it's time.
Now, I've got a monster of a squat workout ahead of me today...chances are good I'll work some floor flops in! Go lift something heavy!!
