7. injuries prevention is key for improvemnt of general health
9. true if done carefully but general warm up is always good before anything else
10. ballistic stretching could cause strains to your muscles if they are not warm enough
11. ballistic stretching is when we bounce on a stretched position
12. dynamic stretching is the best technique to warm up your muscle before physical activities - you can also use some static stretches depending on the needs of what comes next in your training but avoid ballistic stretches
13. this is a good amount of time to get every muscle group ready for exercise
14. if the movement is hold for about 10 second in a static position, there must not be bounces or oscillations otherwise it becomes ballistic
15. because the purpose of a warm up is to speed up heart rate and breathing so that the oxygenated blood can be pumped to each muscle group
