Power Press is a push-up bar set with a board to attach the bars on. It allows you to switch between several push-up positions to target different muscles.
Pro Preset locations
These push-up bars are fixed on a board. This means you will do your push-up routines in the exact same positions each time, so you can really track your progress.
When doing regular push-ups or using regular push-up bars you will position yourself slightly differently each time, meaning it's never the exact same excercise.
