Ballistic Stretches: What They Are & How To Do ThemBallistic stretches are a simple way to give your stretching routine some variation and build flexibility. But they also have some risks you should know about, so you don't hurt yourself.
Ballistic stretches are stretches that use the momentum of the body (with relaxed or tense muscles) to extend your range of motion (ROM).1 They typically involve bouncing or swinging a limb through its full range of movement. 
Bouncing down to touch your toes, or swinging your arms out, are both good examples. They are simple to do, and you can modify many common static stretches to be ballistic.
Yes, it works! Ballistics can increase your flexibility, especially dynamic flexibility (ROM when moving, esp. fast). This has been noted in karate practitioners, though it can help anyone interested in flexibility of movement.2 Plyometrics are a special kind or ballistic stretching that involves stretching the muscles, and then immediately contracting them in an explosive movement.3 It's great for developing explosive power. An especially effective method uses ballistics after regular, static stretching.4 This works very well, and I really like it for building dynamic flexibility. It also helps if you're warmed up, like after a workout. It has also been noted that, "ballistic is more controlled than most athletic activities. Therefore it [ballistic stretching] is likely to be much less dangerous than the sport itself if performed properly and not over aggressively."5 It's also a fun way to try something different in your stretching routine. Mix things up once in a while!
Many sources do not recommend ballistic stretching on the grounds that it is ineffective and can lead to injury.67 And these are valid concerns! The primary argument against ballistics is that if you stretch tissue too fast you can injure it. This is something to be aware of - but just don't be overly aggressive. Also, fast stretching like this can induce the stretch reflex.8 This is a protective reflex that tenses your muscles if they stretch too far too fast, in an effort to keep you from injury. If the stretch reflex kicks in it can actually make you less flexible, as your muscles tense to protect yourself. Your ballistic stretching might actually make you tighter, unfortunately. And finally, ballistically stretching quickly does not give time for the body to adapt to the increased ROM on a neuromuscular level.9 Thus, your increased flexibility may not be as enduring as flexibility gained through longer, more relaxed periods of static stretching.
Unless you really need dynamic flexibility, for martial arts or gymnastics, you don't need ballistics. They are potentially dangerous and you really don't need the flexibility they'll give you. But… If you want to develop dynamic flexibility, and you have movements (like punches, kicks, or dance movements) that take you to the edge of your flexibility, then you might try ballistic stretching. Add it at the end of your static stretching routine, make sure you're still warm, and start slowly. Really, only go in for the ballistic stretching stuff if you have that specialized need for extreme dynamic flexibility - and you're already in pretty good shape! • Click here to learn more about Exercise Stretches & Flexibility!
