Answer:
- warm-up before the start
-schedule the workouts
- work for intervals of time
-maintain a healthy form
Step-by-step explanation:
High-intensity interval training (HIIT) induces important benefits on the health status: increases the metabolic rate, improves cardiovascular endurance, 3-strengthens the skeletal muscles, and increases insulin sensitivity in tissues. Nonetheless, it is important to highlight that there are safety issues that must be taken into account before and during HIIT activities:
1- Warm-up before the start: it is required to avoid cardiovascular accidents (since it improves the heart function)
2- Schedule the workouts: two or three training sessions per week are sufficient.
3- Work for intervals of time: rest intervals are required to prevent fatigue (as the glycogen stores refill)
4- Maintain a healthy form: since it reduces the risk of physical injury during training
