# Usage and Maintenance Instructions
1. Start with light intensity for first-time users to avoid sudden exertion that could lead to muscle strain. Daily training is recommended not to exceed 30 minutes.
2. When adjusting the force, ensure the buckle is fully engaged to prevent it from coming loose during use; store in a dry place to prevent the spring from getting damp and rusting.
