Progress milestones
Estimate how long it will take to achieve full front splits based on your current flexibility and training frequency
Select your current flexibility level using the five cards. Choose the description that best matches where you are right now — be honest, not optimistic. Then enter how many dedicated flexibility training sessions you complete each week.
The estimator returns an approximate timeline to full front splits and a target end date. Below the result, three milestone markers show what progress should look like at 25%, 50%, and 75% of your journey.
The result updates immediately when you change any input — no button press required.
The model is built on observed range-of-motion (ROM) improvement rates from PNF and active flexibility research. The baseline assumes training 3 sessions per week:
This yields 65 weeks at level 1 through 13 weeks at level 5 — consistent with published ROM improvement rates for hip flexor and hamstring tissue.
Training frequency is adjusted using a diminishing-returns curve. Doubling frequency does not halve your timeline — neural adaptation and connective tissue remodelling have biological rate limits:
The 0.65 exponent is derived from research showing roughly 65% efficiency scaling in flexibility gains beyond 3x/week — each additional session yields a smaller incremental benefit. A hard floor of 4 weeks applies regardless of inputs: full splits cannot be achieved in less than a month under any realistic training programme.
How long does it realistically take to get front splits?
Most people at average flexibility need 6–18 months of consistent training 3–5x per week. Genetics, training quality, and consistency matter more than any other factor.
How often should I train for front splits?
Research suggests 3–5 sessions per week of targeted hip flexor and hamstring work. Daily training is possible but diminishing returns apply after 5 sessions.
What type of stretching is most effective for splits?
PNF (Proprioceptive Neuromuscular Facilitation) stretching produces the fastest ROM gains. Active flexibility work (not just passive holds) is also critical for front splits.
Why is my progress stalling on front splits?
Progress plateaus are normal and typically occur every 4–6 weeks. Stalls usually indicate your nervous system needs adaptation time, or training volume needs to increase slightly.
Does age affect front split training timelines?
Age does affect connective tissue pliability and recovery rate. Adults over 35 may need to add 15–25% to estimated timelines and prioritise recovery quality.
