Standing Split

The standing split is a standing hamstring stretch. You stand on one leg and lift the other leg up in front of you as high as you can, keeping it straight.

It’s the standing version of a seated forward fold. Simple to set up, humbling to perform.

Why it matters:

• Stretches the hamstring of the lifted leg under load
• Trains single-leg balance (standing leg)
• Opens the hip flexor of the standing leg if you tilt
• Requires no equipment
• The most functional hamstring stretch for athletes

The reality: most athletes can’t lift their leg much past hip height on day one. That’s fine. The position works at whatever range you have. The goal is progressive range over months, not touching your face on day one.

Setup:

• Stand tall, feet together
• Hold onto a wall, rack, or pole for balance if needed
• Engage your core

Execution:

1. Shift your weight to your left leg (standing leg)
2. Lift your right leg forward, keeping the knee as straight as possible
3. Raise the leg until you feel a hamstring stretch
4. Keep your torso upright (don’t round forward)
5. Hold 20-30 seconds
6. Lower with control
7. Switch sides

Primary Points of Performance:

• Standing leg slightly bent (safer for the knee)
• Lifted leg straight (or as straight as comfortable)
• Torso upright
• Core braced
• Controlled breathing
• Equal time both sides

Common Faults & Fixes:

Progressions:

• Standing hamstring stretch with a strap
• Standing split to hip height
• Standing split to waist height
• Standing split to chest height
• Standing split to shoulder height
• Full standing split (leg vertical or above)

Reps: 2-3 holds of 20-30 seconds per side.

Training role:

• Hamstring mobility (unilateral)
• Single-leg balance
• Pre-training hip opener
• Post-training posterior chain recovery

Programming:

• 2-3 holds of 20-30 seconds per side
• Before or after training
• Daily if desired
• Pair with kick series for a full lower body prep

What it trains:

• Hamstring (stretch of the lifted leg)
• Hip flexors (if torso tilts back slightly)
• Standing leg (balance and stability)
• Core (bracing to stay upright)
• Ankle stability (standing leg)

Why it matters for athletes:

• Hamstring mobility is a limiting factor in squats, deadlifts, and sprinting
• Unilateral hamstring work catches left-right asymmetries
• Single-leg balance is a foundational athletic skill
• Standing versions transfer better to sport than floor versions

Benchmarks:

• Standing split to hip height: baseline
• Standing split to waist height: good
• Standing split to chest height: strong
• Standing split to shoulder height: advanced
• Full standing split: elite

Scaling:

• If you can’t lift your leg: use a strap around the foot
• If balance is limiting: hold a wall or rack
• If torso is rounding: reduce leg height and prioritize upright posture
• If hamstring is tight: bend the knee slightly

Mobility demands addressed:

• Hamstrings: eccentric stretch as the leg lifts
• Hip flexors: stretch of the standing leg if the pelvis tilts back
• Gluteus maximus: stretch of the lifted leg
• Ankle stability: standing leg
• Core: bracing and anti-rotation

Why unilateral mobility matters:

• Most athletes have a dominant side and a tight side
• Bilateral stretches mask asymmetries
• Unilateral drills expose and correct asymmetries
• Standing split in particular shows exactly how much left-right difference you have

Programming notes:

• Progress by lifting higher, not by pushing into pain
• Regress by using a strap or holding onto a wall
• The straightness of the lifted leg matters more than height
• Slow and controlled — momentum-driven swings don’t build mobility

Research context:

• Hamstring flexibility is inversely correlated with hamstring strain injury risk
• Unilateral hamstring mobility drills produce more sport-specific improvements than bilateral stretches
• Single-leg balance is a strong predictor of injury risk in athletes (particularly ankle and knee)

Variations:

• With strap: beginner, foot in strap
• With wall support: balance help
• Free-standing: balance challenge
• With thoracic rotation: more advanced, adds trunk work
• Slow eccentric: emphasis on the control of the descent

When NOT to do it:

• Acute hamstring strain: avoid entirely until cleared
• Acute ankle injury: standing leg cannot support
• Post-surgery on hip, knee, or ankle: consult a professional
• During heavy training: this is a prep or recovery drill, not a max-effort skill

Pairs well with:

• Kick series (dynamic hamstring mobility)
• World’s Greatest Stretch #1 and #2
• Downward facing dog
• Standing forward fold
