Ronan's Brief:

The Pull Up Brace: A protective wearable that keeps resistance bands around the bicep and allows proper form for a one-hand pull-up without irritating the skin.

The pull up brace is a custom design for a former marine named Evan Reichenthal. Evan lost his leg and has a fused elbow from stepping on an IED while deployed in Afghanistan. This does not keep him from  competing in athletic events such as CrossFit, spartan races, and  marathons. One difficulty Evan has had in his training is that he can't use his fused right arm to do pull-ups. His solution has been to wrap a band around his bicep to be able to do the pull ups. While he is not one to complain, frequently this band moves up into his armpit, irritating his skin and compromising his form. The pull-up brace aims to bring allow proper form and comfort while still being light and simple. The original design was bulky and the materials used were to rigid and not durable. The new design gives a more an more athletic feel using compression material instead of yoga mats. The attachment is also more comfortable using padded nylon straps.These overall changes made the brace more simplistic and better for athletic events.

Raphaël's Brief: 

Evan Reichenthal is a former wounded Marine who lost his right leg and the use of his right elbow but still trains and competes at a high-level in various races and is passionate about CrossFit training. In order to perform one-arm pull-ups, he wraps a resistance band around the pull-up bar and puts it under his armpit to provide assistance. However, the band cuts Evan's skin and he has to rest a few days before doing pull-ups again. The new design of the Pull-Up Brace includes a 3D-printed arm brace that traps the resistance band to prevent any damage to his skin. The previous version had two cut PVC pieces strapped together. However, the new version of the Pull-Up brace is designed with adjustable nylon straps and foam to fit comfortably his arm and be tight enough so that the resistance band and the brace itself don't move up his arm. The Pull-Up Brace comes with compression sleeves to maximize comfort and avoid skin irritation on the sides.
