Crunch Floor — questions
What muscles does the Crunch Floor work?
The Crunch Floor primarily targets the Abs. It also recruits the Hip Flexors as secondary movers.
What equipment do I need for the Crunch Floor?
None — the Crunch Floor uses your bodyweight only, so it works at home with nothing but floor space.
Is the Crunch Floor suitable for beginners?
Yes. It is classed as a beginner movement: the pattern is simple enough to learn in a session and easy to scale by adjusting range of motion or load.
What can I do instead of the Crunch Floor?
3/4 Sit-up, 45° Side Bend, Air Bike train the same muscles and make good substitutes when the equipment is taken or the movement does not suit you.
