Optimal rest time between sets for strength

You finished your set. Now what?

The time between sets might seem like wasted time, but it’s actually when your body prepares for the next effort. Rest too short and you can’t perform. Rest too long and you cool down.

Here’s what the research says and how to apply it to 5x5.

The Science of Rest Periods

Your muscles have limited fuel stores (ATP and creatine phosphate) that power heavy lifting. These deplete rapidly during a set and require time to replenish.

A 2016 meta-analysis in Sports Medicine examined rest periods across multiple studies:

• For strength: Longer rest (3+ minutes) produced significantly better results than short rest (1 minute)
• For hypertrophy: Results were similar across rest periods when sets were completed
• For endurance: Shorter rest maintained the conditioning stimulus

The researchers concluded that strength-focused training should use 3-5 minutes between heavy sets.

Recommended Rest Times for 5x5

Squat: 3-5 minutes

Squats are the most demanding exercise. They fatigue your entire body and require full recovery between sets.

Light weight (first few weeks): 2-3 minutes Challenging weight: 3-4 minutes Near your limit: 5 minutes

If you’re rushing squats with 90-second rest, you’re limiting how much weight you can lift.

Deadlift: 3-5 minutes

Though you only do one working set, the warmup sets also need adequate rest.

Warmup sets: 2 minutes Working set preparation: 3-5 minutes after last warmup

Bench Press: 2-4 minutes

Bench uses less total muscle mass than squats, so rest can be slightly shorter.

Light weight: 2 minutes Moderate weight: 3 minutes Heavy weight: 4 minutes

Overhead Press: 2-4 minutes

Similar to bench, though OHP often feels harder relative to the weight.

Early sets: 2 minutes Later sets: 3-4 minutes

Barbell Row: 2-3 minutes

Rows are less systemically demanding. Shorter rest works.

All sets: 2-3 minutes

How to Know If You’re Resting Enough

Signs you need more rest:

• Each set feels harder than it should
• Reps decrease significantly across sets (5,5,5,4,3 pattern)
• You feel breathless when starting the next set
• Grip or stabilizer muscles fail before target muscles

Signs you’re resting too long:

• You feel cold or stiff when starting next set
• You’ve lost mental focus
• Your warmup effect has dissipated
• Total workout time exceeds 90 minutes

The 90-Second Mistake

Some programs prescribe 60-90 second rest for “metabolic conditioning” or “time efficiency.”

For strength training, this is counterproductive.

A 2014 study in the Journal of Strength and Conditioning Research had lifters train with either 1-minute or 3-minute rest periods over 8 weeks. The 3-minute group gained significantly more strength and similar muscle mass.

Short rest might burn more calories during the session, but it reduces the weight you can lift, which reduces the strength stimulus.

If your goal is strength (the point of 5x5), rest adequately. Proper rest between sets is essential for hitting your target reps and maintaining steady progression over time.

Rest and Total Workout Time

With proper rest, a 5x5 workout takes 45-75 minutes:

Squat:

• Warmup: 10 minutes
• 5 working sets × 3-4 min rest: 15-20 minutes
• Total: 25-30 minutes

Bench/Press:

• Warmup: 5-7 minutes
• 5 working sets × 2-3 min rest: 10-15 minutes
• Total: 15-22 minutes

Row/Deadlift:

• Warmup: 5 minutes
• Working sets/set × 2-3 min rest: 8-12 minutes
• Total: 13-17 minutes

Full workout: 53-69 minutes

If you’re finishing in 30 minutes, you’re rushing. If you’re taking 2 hours, you’re probably on your phone.

What to Do During Rest

Good use of rest time:

• Light pacing to maintain blood flow
• Gentle stretching or mobility for uninvolved muscles
• Mental rehearsal of technique
• Reviewing training notes
• Staying warm (don’t sit in AC draft)

Avoid during rest time:

• Heavy cardio (elevates heart rate, induces fatigue)
• Intense stretching of muscles you’re about to use
• Complete stillness for long periods (you’ll tighten up)
• Distracting conversations or phone scrolling

Using a Timer

Many lifters underestimate their rest times. “3 minutes” becomes 90 seconds because they’re eager.

Solution: Use a timer.

Set it after each set. When it goes off, start your next set (or final approach routine).

The Lift5x5 app has built-in rest timers that automatically start when you log a set. This removes guesswork.

Adjusting Rest Over Time

As weights increase, rest needs increase too.

Week 1-4 (light weights): 2 minutes is fine for everything.

Months 2-3 (moderate weights): 3 minutes for squats, 2-3 for others.

Months 4+ (heavy weights): 3-5 minutes for squats and deadlifts, 3-4 for bench.

Don’t feel guilty about longer rest at heavier weights. It’s not laziness — it’s proper recovery. As the progression guide explains, the weights get heavy enough that adequate rest becomes the difference between completing your sets and triggering a deload.

When to Shorten Rest (Intentionally)

There are situations where shorter rest makes sense:

Warmup sets: 30-60 seconds between light warmup sets is fine.

Deload weeks: When weights are intentionally light, shorter rest maintains workout density.

Time constraints: If you genuinely have only 30 minutes, shorter rest with slightly reduced weight beats skipping the workout.

Accessory work: Chin-ups, curls, and other accessories don’t need 3-minute rest.

The Bottom Line

For 5x5 strength training:

• Heavy compounds: 3-5 minutes
• Moderate compounds: 2-4 minutes
• Light accessories: 1-2 minutes

Rest enough to perform your best on each set. Strength training is not cardio.
