Use Isometric Stretching To Gain Significant FlexibilityIsometric stretching (IS) is one of the fastest and most effective ways of developing flexibility. In a matter of days or weeks you can become substantially more flexible, and develop strength in your flexible limbs. I personally think this technique is awesome! So…
Isometric stretching is where you move into a position to stretch, hold the stretch, and tense (isometrically contract) your stretched muscles, and then relax & stretch some more. Pretty simple, on the face of it. Isometric means "same distance", which is a reference to how you contract your muscles.1 You contract your stretched muscles without moving - like how you contract your bicep to show off, while keeping your arm in one position. Alternatively, while stretching your legs on the floor you might grab your foot. This would allow you to tense your calf, trying to point your foot away from your leg, while you use your hand to hold your foot back. Then you relax the calf and stretch it even further.  Isometric stretches are typically held in their contracted position longer than PNF stretches, a similar stretching technique.2 PNF stretches are also more precise about different muscle contractions and how you should move to increase your range of motion (ROM).
It's virtually impossible to tense all of your muscle fibers at once, even when you're trying with all your might. This is how your body keeps you from damaging yourself. In an isometric muscle contraction, some fibers in the muscle are pulled on by the contracting muscle - stretching the resting muscle fibers & contracting the tensing fibers. In the isometric contraction the contracting fibers pull on the resting fibers, stretching them. The resting fibers then get stretched more, and when you subsequently relax your muscle the contracting fibers relax as well and allow your muscle to lengthen more than normal.3 Giving you greater flexibility almost immediately. Pretty cool (and useful) science!
• It's more effective than active or passive stretching alone.4 • It builds strength in the tensed muscles. • It seems to decrease the pain associated with stretching.5 • IS is great for speed training. The tension from the isometric contraction strengthens the muscles at the very end of the range of motion you're working. This is extremely useful if you need strength and power at the end of your range of motion. Say for kicking, punching, leg movements in dance, or keeping a joint aligned.6 - WARNING - Isometric stretches should not be done by children or adolescents. Their bones are still growing and IS could damage their connective tissue.7, 8
First, make sure you're thoroughly warmed up before you try these stretches. This'll make the stretching easier, and you'll gain more range of motion. Also, do no more than 1 isometric stretching session a day per muscle group.9 IS puts a great strain on the muscles being stretched and you don't want to hurt yourself with overzealous enthusiasm. Trust me, isometric stretching will build your flexibility fast with just 1 session a day. Use a floor, wall, or your own limbs to apply resistance to your isometric contraction. Tense your muscles, and make sure you don't move when you're tensing up. - The IS Method10 - That's all there is to it. Really. So simple, and yet so effective at building range of motion and flexibility. Give it a try! • Click here to learn more about Exercise Stretches & Flexibility! OR
