Crossfit Trainer Practice Test Level 1 - The Complete 2025 All-in-One Guide to Passing Your Certification

In a GHD sit-up progression, starting with an AB mat and then practicing on the GHD machine is an effective initial step for beginners. The AB mat provides support for the lower back while allowing the user to work on the core engagement required for sit-ups. This approach helps newcomers to develop the necessary strength and stability without the added complexity and intensity of the GHD machine from the outset.

Once athletes are comfortable and proficient with the AB mat variations, they can safely transition to the GHD machine, where the unique design requires additional hip flexor and core strength due to the increased range of motion. This progression minimizes the risk of strain and builds foundational skills in a controlled manner.

The other options involve either full sit-ups without assistance, which may be too advanced, or ground sit-ups that do not specifically address the unique demands of the GHD format. The option about holding the superman position lacks relevance in the context of sit-up progression, as it does not directly correlate with the mechanics of the GHD sit-up. Overall, using the AB mat as a preparatory tool is a structured approach to ensure that beginners build up their strength systematically.
