The 300+ training movement videos included in BULLTZ are all certified through the FMS (Functional Movement Screening) system, with each movement containing three viewpoint demonstrations (45-degree side view, frontal view, and close-ups of the equipment) and labeled with 17 body-critical point trajectories. The video content has been cross-checked by five ACE-certified coaches to ensure that the details meet NASM standards. Special design features include a "Common Errors Comparison Demonstration" module, for example, a hard pulling movement that shows the difference in spinal curvature between an arched back error (highlighted by the red skeleton) and the correct position (highlighted in green) side by side.
The knowledge system adopts a step-by-step structure, dividing the movements into four levels according to their difficulty, and users need to pass the stability test of the previous levels before unlocking the advanced content. The video library specifically reinforces three specialized dimensions: breathing rhythm tips (e.g., "Exhale for 2 seconds when pushing up"), muscle perception guidance ("Feel the latissimus dorsi muscle contracting toward the midline of the spine"), and equipment fine-tuning advice ("The Smith rack should be placed at hip height. safety pin should be placed at hip height"). The study showed that the efficiency of the user group's movement learning increased by 60% and the error rate was 73% lower than that of the user group who only watched the illustrated instructions, which is the most complete standardized movement instruction system on the mobile terminal.
