Stretching for Lifters: When and How

Should you stretch before lifting? After? Both? The advice on stretching has flip-flopped so many times that most lifters are thoroughly confused.

Let's cut through the noise and look at what the research actually says.

The Two Types of Stretching

First, we need to distinguish between the two main approaches:

Static stretching: Holding a position for 15-60+ seconds (touching your toes and holding)

Dynamic stretching: Moving through ranges of motion repeatedly (leg swings, arm circles, walking lunges)

These have very different effects and appropriate uses.

Pre-Workout: The Research Is Clear

The evidence on pre-workout stretching is surprisingly consistent.

Static stretching before lifting: Not recommended

A meta-analysis by Simic et al. (2013) examined 104 studies and found that static stretching before exercise reduces strength by an average of 5.5% and power by about 2%.

That's not huge, but why give away free gains?

Research on stretch duration suggests that stretches held under 45 seconds have minimal negative effects on strength, while longer holds can create more significant deficits (Simic et al., 2013).

Dynamic stretching before lifting: Recommended

The same meta-analysis found that dynamic stretching either had neutral or slightly positive effects on performance. It increases muscle temperature, improves range of motion temporarily, and primes the nervous system.

Bottom line: Save static stretching for after. Use dynamic movement to warm up.

Post-Workout Stretching

This is where static stretching makes sense — if you use it strategically.

Systematic reviews have found that post-workout stretching doesn't significantly reduce muscle soreness or prevent injury (Herbert et al., 2011). So if that's your goal, you may be disappointed.

However, static stretching after training can:

• Improve long-term flexibility when done consistently
• Help with parasympathetic recovery (calming down)
• Feel good psychologically

If improving flexibility is your goal, post-workout is an appropriate time since muscles are warm and pliable.

What Lifters Actually Need

Here's the practical framework:

Pre-Workout Protocol

1. General warm-up (5 minutes) Light cardio to raise body temperature — bike, rower, walking.

2. Dynamic mobility (5-10 minutes) Focus on the joints you'll use:

For lower body days:

• Walking lunges with rotation
• Leg swings (front-to-back and side-to-side)
• Hip circles
• Bodyweight squats

For upper body days:

• Arm circles
• Band pull-aparts
• Cat-cow stretches
• Shoulder dislocates with a band

3. Movement-specific ramping Work up to your working weights with lighter sets. This is part of warming up that many lifters underestimate.

Post-Workout Protocol

If you want to include stretching after training:

Hold each stretch 30-60 seconds Shorter holds don't create lasting flexibility changes. Bandy & Irion (1994) found that 30 seconds was the minimum effective dose, with no additional benefit beyond 60 seconds.

Focus on tight areas Don't stretch everything — focus on the muscles you trained and areas where you're genuinely restricted.

Common areas for lifters:

• Hip flexors (tight from sitting and squatting)
• Lats (restrict overhead mobility)
• Pecs (round shoulders forward)
• Hamstrings (tight from deadlifts and sitting)

Do You Even Need to Stretch?

Here's a question worth asking: do you actually have flexibility limitations that affect your lifting performance?

If you can:

• Squat to full depth with good form
• Deadlift without excessive rounding
• Press overhead without compensating through your back
• Achieve the positions your training requires

...then stretching is optional. It's a tool, not a requirement.

Iridium's exercise notes let you flag restricted movements during a session — the AI incorporates these notes when building your next workout. If your hip flexors kept limiting your squat depth, you don't have to remember to mention it next time.

Many successful lifters never do traditional stretching. Instead, they:

• Train through full ranges of motion
• Do mobility work as part of their warm-up
• Include some loaded stretching (like RDLs or deep squats)

This approach can maintain functional flexibility without dedicated stretching sessions.

When Stretching Becomes Important

That said, stretching matters more in certain situations:

If you sit all day: Hip flexors and hamstrings tighten, affecting squat and deadlift mechanics.

If you have mobility restrictions: Can't hit depth? Can't get overhead? Address the limitation.

If you're coming back from injury: Restoring range of motion may require dedicated stretching.

If flexibility is your goal: Some people want to be more flexible for its own sake, and that's valid.

A Practical Weekly Approach

Here's a sustainable framework:

Every training session:

• Dynamic warm-up: 5-10 minutes
• Movement-specific preparation: 5-10 minutes

2-3 times per week (optional):

• Post-workout static stretching: 10-15 minutes
• Focus on genuinely tight areas

Once per week (optional):

• Dedicated mobility session: 20-30 minutes
• Combine stretching, foam rolling, and movement

Track what you're doing and whether it's helping. If you've been stretching your hamstrings for six months with no improvement, something needs to change.

The Bottom Line

Pre-workout: Dynamic movements, not static holds. Save stretching for later.

Post-workout: Static stretching is fine if you want it. It won't reduce soreness, but it can improve flexibility over time.

Most important: Train through full ranges of motion. This maintains functional flexibility for most people.

Don't stretch because you think you should. Stretch because you've identified a limitation worth addressing.
