One goal of most dancers is to increase their flexibility. Being limber helps a dancer to avoid injury and also allows them to accomplish more technical moves. Being more flexible allows a dancer to kick higher, touch their toes in a toe touch, do the splits, and many more moves.
So how does a dancer increase their flexibility? In order for the muscle to lengthen, a dancer must hold their stretch for 30 seconds to 1 minute. Pulsing a stretch, or bouncing in a stretch may be fun to do, but it actually teaches the muscle to contract and decreases flexibility. When a dancer holds a stretch they should remain still like a statue. Holding a stretch for less than 30 seconds will not lengthen the muscle, so make sure to watch the clock while you're stretching.
Frequency will also help you increase flexibility. Finding 8-10 minutes a day to stretch can have a huge effect on your flexibility. Stretching while watching T.V. is a great way to relax and lengthen your muscles at the same time.
