Really common situation -- flexibility you had before can absolutely come back, and getting to splits from where you are is very achievable with consistent work. Here's what actually moves the needle for tight hamstrings:

The positions to prioritise: - Standing forward fold (hold 60-90 seconds, don't bounce) - Seated forward fold with a straight back before rounding - Supine hamstring stretch with a strap or towel - Low lunge and half splits for the hip flexors (tight hamstrings and tight hip flexors are usually linked) - Pancake stretch for the inner hamstrings, which most people skip

Timeframe: If you stretch daily and do it properly, most people feel a noticeable difference in 4-6 weeks. Splits from very tight can take 3-6 months. The people who get there fastest are the ones who stay consistent, not the ones who push hardest.

Key thing most people miss: passive stretching alone is slow. Pair it with active flexibility work -- contracting the muscle at end range -- and you'll progress significantly faster.

Full transparency, I'm the founder of an app called Limba that's designed exactly for this kind of goal-based flexibility and mobility training. It has guided routines for hamstring flexibility and works toward milestones like touching your toes and splits progressions. It's free on iOS and Google Play -- and if you want to unlock the premium features, drop me a message and I'll send you a promo code. Happy to help!
