Final answer:
To improve Range of Motion (ROM), it's generally recommended to start with 2-3 exercise sessions per week, allowing for recovery and consistent improvement over a 3 to 4-week period.
Step-by-step explanation:
In order to improve Range of Motion (ROM), the frequency of exercise sessions can vary depending on the individual's current level of mobility, specific goals, and potential presence of any injuries. However, general guidelines for ROM improvement suggest a frequency of 2-3 sessions per week as a starting point. This will allow adequate time for recovery between sessions while ensuring consistent progression. It is essential to tailor the approach to each individual's response to exercise and adjust the frequency accordingly. Hence, for a timeframe of 3 to 4 weeks, the most recommended option is b) 2-3 sessions/week.
