• Use renewable energy sources to power the system.
• Recycle and dispose of electronic waste responsibly.
• Promote sustainable practices among users.

Limbers play a crucial role in ensuring the smooth operation of dance, aerobics, and other physical activity programs. Their primary responsibility is to lead and guide participants through a series of stretches and exercises designed to increase flexibility, reduce muscle tension, and improve range of motion.

1. Leading and Guiding Participants

Limbers lead participants through a variety of stretches and exercises, providing clear instructions and demonstrations.

• Create and implement warm-up and cool-down routines.
• Instruct participants on proper stretching techniques.

2. Assessing and Monitoring Flexibility

Limbers assess participants’ flexibility levels and track their progress over time.

• Conduct flexibility assessments using various methods.
• Monitor participants’ progress and adjust routines accordingly.

3. Promoting Safe Exercise Practices

Limbers ensure that participants engage in stretching and exercises safely.

• Provide proper instruction on safe stretching techniques
• Monitor participants for signs of discomfort or pain and modify exercises as needed.

4. Collaboration with Other Professionals

Limbers may collaborate with other professionals, such as dance instructors, fitness trainers, and physical therapists to ensure that participants receive a comprehensive approach to stretching and flexibility.

• Collaborate with instructors to design stretching routines that complement other activities.
• Consult with physical therapists to address specific flexibility needs.
