- Ensure the exercise environment is safe and free of hazards; use appropriately sized equipment
- begin with 5-10 minutes of dynamic warm-up
- Low to moderate intensity 2-3 times/ week, with 1 to 2 sets (progress to 3-5) 8-12 exercises
- Proper form and technique is prioritized over progression in intensity
- Include exercises that challenge balance and coordination
- vary the program to optimize gains, have fun and avoid boredom
