What's your stretching routine/goals? Also, what kind of other workouts do you do in addition to stretching? This can limit what is possible for you to some extent. I went from pretty inflexible (just barely able to touch my toes) to pretty flexible (palms easily to the floor from standing, just about full front splits/pancake straddle. Middle split not so much, maybe someday...Seen a lot of shoulder/back flexibility improvement as well). How I did that:
- Quit track.
- Take dance/circus classes
- Stretch when bored
Thing is, number one was pretty key for me. While I was still training competitively I was just flexible enough to avoid getting injured, but my muscles (especially hamstrings) were tight in all the wrong places for significant flexibility. I still run, just not to the same level of training. It's definitely possible to have both strength/speed and flexibility (in fact strength is important to train alongside the stretching itself), but certain activities and body types are definitely going to make it tougher to get those crazy moves that lifelong dancers/gymnasts/etc. have.
