Meet the Helm: a core training system that lets you try more dynamic pushups and other bodyweight exercises. Just place it on an unstable surface such as the Bosu to push your body harder. The Helm has 3 handle positions and lets you focus on abs, arms, shoulders, and your back.
The Helm has a portable design and doesn’t require assembly. It works on the ground, Swiss balls, and everywhere in between. Costs under $85 at this time.
