How Long Does It Take to Learn to Do a Split on Both Sides?

Quick Answer

For the average adult with no flexibility training background, achieving a full split on both the left and right sides typically takes 3–12 months of consistent daily stretching. Getting your first side down is usually the faster part (2–6 months), while the weaker side often takes an additional 1–4 months. Naturally flexible individuals or those with dance or martial arts backgrounds may achieve both sides in as little as 4–8 weeks.

Expected Timeline by Starting Flexibility

Starting Point	First Side	Both Sides
Already somewhat flexible	4–8 weeks	2–4 months
Average adult flexibility	2–6 months	4–8 months
Very tight / sedentary	6–9 months	8–12+ months
Over 40 with no stretching history	8–12 months	12–18+ months

Why Both Sides Takes Longer Than One

Most people have a dominant side with naturally greater hip flexibility. This asymmetry is completely normal and results from habitual movement patterns, dominant leg usage, and even how you sit throughout the day. Training your non-dominant side requires additional patience because the hip flexors, hamstrings, and adductors on that side are typically tighter and less responsive to stretching initially.

The Science of Flexibility Training

How Muscles Lengthen

Stretching does not literally make muscles longer overnight. Instead, consistent stretching increases your nervous system's tolerance to the stretched position (stretch tolerance) and gradually remodels the connective tissue. This is why daily practice is essential — your body needs repeated signals that it is safe to allow greater range of motion.

The Role of Fascia and Connective Tissue

The fascial network surrounding your muscles plays a significant role in flexibility. Fascia responds to sustained, gentle loading over time. This is why passive stretching held for 60–90 seconds per position is more effective for splits training than quick, bouncing stretches.

Recommended Training Protocol

Daily Practice (20–30 Minutes)

1. Warm up first — 5–10 minutes of light cardio (jogging, jumping jacks, or dynamic leg swings) to increase blood flow and tissue temperature.
2. Dynamic stretches — Leg swings (front-to-back and side-to-side), lunging hip circles, and deep squat holds.
3. Progressive static stretches — Hold each position for 60–90 seconds:

• Low lunge (hip flexor stretch)
• Half split (hamstring stretch)
• Pigeon pose (hip external rotation)
• Straddle stretch (adductors)
• Full split attempt with yoga blocks for support

1. PNF stretching — Contract-relax techniques, where you gently push against resistance for 5 seconds then relax deeper into the stretch, can accelerate progress.

Training Both Sides Equally

Always stretch both sides during every session, even if one side feels much easier. Spending slightly more time on your tighter side (an extra 30 seconds per stretch) helps close the gap without neglecting the flexible side.

Common Mistakes That Slow Progress

• Skipping the warm-up: Stretching cold muscles is less effective and increases injury risk.
• Inconsistency: Missing multiple days resets some of your progress. Daily practice, even for just 15 minutes, beats occasional long sessions.
• Pushing through pain: Sharp or stabbing pain is a warning sign. Effective stretching should feel like a strong pull, not pain.
• Ignoring hip flexors: Tight hip flexors are often the hidden bottleneck preventing full splits. Prioritize deep lunge stretches.
• Only training the front split: The muscles used in left-side and right-side splits overlap but are not identical. Train each side independently.

Age and Flexibility

While children and teenagers tend to achieve splits faster due to more pliable connective tissue, adults of any age can reach full splits with dedicated training. Research shows that older adults respond well to consistent stretching protocols, though the timeline may be longer. The key variable is consistency, not age.
