Rhythmic Weight Training Exercise in the Body Challenge Class: Guidelines for Designing Group Exercise Programs

Abstract

The Body Challenge class is a group exercise program developed by Siriraj Fitness Center to promote holistic physical fitness. It targets individuals with limited time, little experience with fitness equipment, or those seeking an engaging alternative to traditional workouts. The program combines strength training, functional movement, and music rhythm, using Beats Per Minute (BPM) to guide movement tempo. This approach enhances neuromuscular coordination, reduces fatigue, and increases exercise motivation. This article introduces a conceptual framework and practical example for designing a rhythm-based strength training class, based on real-world implementation. It highlights strategies for selecting music that aligns with each training phase to improve precision, safety, and training effectiveness. The framework can be applied in health centers, hospitals, and fitness facilities to create structured group exercise programs that are enjoyable, music-driven, and accessible to diverse participants. It is especially relevant for individuals with constraints in time, skill, or equipment. This article, based on practical class experience, lays the groundwork for future program development and outcome evaluation.
