1. how long should static stretches be held during the cool - down phase in general cardio workout programming?5 - 10 seconds15 - 30 seconds30 - 45 seconds15 - 60 seconds5. what is the main focus during dynamic stretches in warm - up?major muscle groupsbreathing techniquesarm movementsstrengthening legs6. what is the purpose of the low - intensity aerobic exercise during the cool - down phase?improve flexibilityreduce heart rateenhance enduranceincrease intensity

Explanation:

1. Static stretches during the cool - down phase are typically held for 15 - 30 seconds. This duration allows for effective relaxation and lengthening of the muscles without over - stressing them.
2. Dynamic stretches in the warm - up are mainly focused on major muscle groups. This helps to prepare the body for the upcoming exercise by increasing blood flow and range of motion in the key muscle areas.
3. The purpose of low - intensity aerobic exercise during the cool - down phase is to reduce heart rate. After a more intense workout, gradually lowering the heart rate helps to prevent blood pooling and promotes a smoother transition to the resting state.

Answer:

1. 15 - 30 seconds
2. Major muscle groups
3. Reduce heart rate
