Hi Aussie_coach i have to disagree with you that
strength is the most essential element in creating an outstanding gymnast
. Otherwise this suggests that a Rings specialist should be phenominal on all apparatus, what about the fact that flexibility is a huge component on a Women's floor exercises and Beam? Not to mention that most skills have technical requirements that require a great deal of flexibility (eg.. Split leaps, jam dislocates on bars, walkovers, and so on).. so really that is a very misleading comment. Gymnastics is a balance sport you need to match flexibility, and strength in order to be an outstanding gymnast. As gymnasticsbabie said herself, the more technical you get the greater the flexibility component need to show the high degree of amplitude.
I also have to disagree with
the first 30 seconds will not gain you any flexibility,
. There is PLENTY of evidence to contradict this statement (if want references i can provide them). The first 25 seconds are actually the most effective for the time invested. You are right to when you say that 2 min is better then 1, and 3 is most likely better then 2 and so on (there is no evidence to suggest a cap time), but if don't have the time to do 2 min per stretch in a session (like most gyms) then no one would be getting any benefits.. Well i can tell you that in our gym no one does more then 30sec per stretch and everyone gets down. sooner or later. One thing that is important is not to get stagnant, you need to keep pushing your stretching, If you have been doing 30sec for like 2-3 months, then increase the time, or increase the number of times you repeat the stretch. 30 sec rotation between stretches actually works very well.
If i were you gymnasticsbabie i would do this. Stretch in the morning as you get out of bed (generally speaking your muscles are warm, and your CNS is maybe not quite fully fucntional so it wont fight you as much). I would do as aussie_coach suggested a quick light warm-up...something like 50 start jumps, 10 push-ups (this is really dependant on how hard 1 push up is for you really), so light gentle dynamic kicks front, back, side, i would do some basic abs and lower back work as well. This constitutes as a light dynamic warm up.
Following this i would do rotation of pancake holds, and side splits hold each for 30 the least and if you have the time go up to 2min (to start anyways). Repeat each stretch at least 3 times. Because of the rotation you don't need to include a rest, but if you want rest 20sec between stretches will do.
Repeat this twice a day (at night before a shower is also a good time) on alternating days (as Aussie_coach suggested). Same procedure as above.. Do this for 4 weeks, and then increase the intensity, by either elevating you middles (remember to alternate legs if you elevate 1 at a time), increase the time (if you are under 2min). Push yourself to new limits (pain tolerance wise), if you can get someone to stretch you, by pushing on you in the pancake or elvate your legs, or sit against a wall and get someone to push your legs against the wall (MEAN!!! but great stretch for middles), as well increase the frequency, do 2-3 days in a row, then rest 1 day, then again 2-3days in a row and so. Do for another 4 weeks and increase again and increase the volume, so more repetitions from 3 to 4-5, and do the stretching 3 times a day. and work it 4-5days in row then rest. .
If you do this i am 99.9% sure that you will see the benefits you need.
