A push-up board, also known as a push-up rack or push-up stand, is a fitness accessory designed to enhance the effectiveness and variety of push-up exercises. It consists of a sturdy platform or board with multiple hand placement options and possibly other features to target specific muscle groups. 1. Board or Platform: The main part of the push-up board is a flat and durable platform made of plastic, rubber, or other sturdy materials. It provides stability and support during push-up exercises. 2. Hand Placement Zones: Push-up boards usually have multiple zones or slots where you can position your hands. These zones are marked with different colors or labels to indicate the specific muscles targeted by each hand placement. For example, there may be zones for targeting the chest, shoulders, triceps, or a combination of muscle groups. 3. Ergonomic Design: Push-up boards are designed to promote correct form and wrist alignment during push-ups. They may feature inclined or textured handles that provide a comfortable grip and reduce strain on the wrists.
