【iHealth Fitness 4-Week Challenge Program】
Overview
All participants engaged in a supervised iHealth Fitness 4-Week Challenge program three days per week, supplemented by one personal training (PT) session per week, totaling 16 workouts over the four-week protocol.
Workout Structure
Each circuit included 14 exercises targeting various muscle groups, such as:
Upper Body: Elbow flexion/extension, shoulder press/lat pull, chest press/seated row.
Lower Body: Knee flexion/extension, hip abductor/adductor, squat, horizontal leg press, hip extension.
Core: Abdominal crunch/back extension, obliques, side bends.
Full Body: Stepping, shoulder shrug/dip.
The exercises utilized a combination of pneumatic or hydraulic resistance to effectively target opposing muscle groups.
Session Format
Duration: Each workout lasted approximately 30-40 minutes.
Repetitions: Participants were instructed to complete as many repetitions as possible within a 30-second time frame for each exercise.
Calisthenics: After each resistance exercise, participants performed 30 seconds of floor-based calisthenics (e.g., running in place, arm circles) to maintain a heart rate of 60% to 80% of their maximum.
Personal Training Sessions
In addition to the circuit workouts, participants attended one personal training session per week. These sessions focused on individualized fitness goals, technique refinement, and motivation, providing personalized support to enhance overall performance.
Supervision and Support
All workouts, including PT sessions, were supervised by trained fitness instructors who provided guidance on proper technique and ensured participants maintained appropriate intensity levels.
Compliance and Flexibility
Participants were required to complete at least 70% of the sessions (minimum of 12 out of 16). They had the option to add an extra workout on non-consecutive days to help maintain compliance.
