#6 Crunch Partner - details by Mcneim2
More details on the options of this design. Depending on the targeted final product cost and the targeted tooling cost there are many different ways to create the center hinge. It would be best to conduct some FEA and validate the ribs with a prototype.

#2 Crunch partner by Mcneim2
Use your own body weight to hold your feet down for crunches. Made of sturdy yet light ABS this design folds flat for easy transport. You unfold the product, sit down at the far end and strap your feet in. This design has room for branding and customization like a cut out for a handle. This is a concept sketch and I will build the CAD based on any questions or comments.
