Stretching

Stretching

Definition

Stretching is a practice that consists of lengthening muscles and connective tissues beyond their resting length, to increase flexibility and joint range of motion.

An ancient practice (yoga, gymnastics, dance), it remains debated in modern fitness: when to use it, at what frequency, in what form?

💡 Stretching ≠ mobility. Stretching works passive muscle length. Mobility combines flexibility, motor control, and stability.

The 4 types of stretching

1. Static passive stretching

You hold a stretch position for 20-60 seconds. The most well-known form. Ideal at end of session or as standalone routine.

2. Static active stretching

You hold a position by contracting the antagonist muscle (e.g., raising the leg unaided). Builds active flexibility.

3. Dynamic stretching

Wide controlled movements (e.g., leg swings). Ideal as warm-up before training.

4. PNF (Proprioceptive Neuromuscular Facilitation)

Alternating contraction-relaxation. The most effective method for flexibility gains, but the most demanding.

When to stretch?

Moment	Recommended type	Duration
Before session	Dynamic	5-10 min
During session	None (or very light)	—
After session	Light static passive	5-10 min
Standalone routine	Static + PNF	20-40 min

⚠️ Stretching a muscle for long periods (60s+) BEFORE a strength session temporarily reduces force production by 5-10%. Avoid static stretching before heavy exercises.

Real benefits of stretching

• ✅ Increased joint range of motion (science is clear)
• ✅ Subjective sense of well-being and relaxation
• ✅ Lower baseline muscle tone (muscles less "tight")
• ✅ Long-term posture improvement
• ✅ Mental recovery tool (relaxation, breathing)

Myths to debunk

Science has challenged several beliefs:

• ❌ "Stretching prevents injury": negligible effect per meta-analyses
• ❌ "Stretching reduces DOMS": false, no significant effect
• ❌ "Stretching improves performance": false for static before effort
• ❌ "You must stretch after every session": not mandatory

Sample 15-minute routine

Daily routine for global flexibility gains:

Stretch	Duration
Pigeon (glutes)	2 × 30s per side
Hamstrings (standing or seated)	2 × 30s per side
Standing quad stretch	2 × 30s per side
Adductors (butterfly)	2 × 45s
Chest (door or wall)	2 × 30s per side
Neck and traps	30s per direction

Common mistakes

• ❌ Stretching abruptly when cold (strain risk)
• ❌ Long static stretches before strength session
• ❌ Going past pain (discomfort should stay moderate)
• ❌ Stretching an injured muscle (worsens injury)
• ❌ Holding breath during stretch

Key takeaways

Stretching is useful but overrated in some cases. Dynamic stretching before session, light static after, dedicated routine 2-3x/week for flexibility. Don't expect it to prevent injury or reduce DOMS, that's not its role. For joint health and performance, prioritize mobility.
