How many calories does a 5x5 workout burn?

A typical 5x5 session burns roughly 200-400 calories depending on the weights used, your body size, and rest periods. This is modest compared to an hour of running or cycling. But the real metabolic advantage of 5x5 isn't the calories burned during the session - it's the muscle built and maintained, which increases your resting metabolic rate 24 hours a day.

Should I add cardio to 5x5 for faster fat loss?

You can, but keep it moderate. Light cardio on rest days - walking, cycling, swimming - supports recovery and adds calorie expenditure without interfering with strength training. Avoid high-intensity cardio that competes with your lifting recovery. The deficit should come primarily from your diet, not from excessive exercise.

Why isn't my weight dropping even though I look leaner?

Because you're likely gaining muscle while losing fat. Muscle is denser than fat, so you can look dramatically different without the scale moving much. This is especially common in beginners who are simultaneously building muscle and losing fat. Track your waist measurement, take progress photos, and notice how your clothes fit - these tell you more than the scale.

Can I do 5x5 on a low-calorie diet?

A moderate deficit of 300-500 calories works best. Extreme calorie restriction impairs recovery, reduces strength, and causes muscle loss - the opposite of what you want. If your deficit is too aggressive, you won't be able to recover from 5x5 sessions and your training will suffer. Eat enough to fuel your training while creating a moderate shortfall.

Is 5x5 better than cardio for fat loss?

They serve different purposes. Cardio burns more calories per session. But 5x5 builds and preserves muscle, which keeps your metabolism higher and ensures the weight you lose is fat, not muscle. The ideal approach combines both: 5x5 three days per week for strength and muscle, plus moderate cardio or walking on rest days for additional calorie expenditure. If you can only pick one, choose 5x5.

Can 5x5 help you lose weight?

Let’s answer the question directly: 5x5 alone doesn’t cause significant weight loss. Diet does that. But 5x5 is the single best complement to a fat-loss diet because it determines whether the weight you lose comes from fat or muscle.

Most people who “diet and exercise” lose muscle along with fat, end up with a slower metabolism, and look worse at the same weight than when they started. A structured strength program prevents all of that. Here’s how to use 5x5 to actually transform your body.

Why strength training is essential during fat loss

When you eat fewer calories than you burn, your body needs to get the missing energy from somewhere. It has two options: break down fat tissue or break down muscle tissue. Without a strong stimulus to keep your muscles, your body will happily sacrifice both.

What happens without strength training

A 2008 study in the American Journal of Clinical Nutrition followed dieters with and without resistance training. The diet-only group lost weight - but 25-30% of it was lean mass. They lost muscle, their metabolism dropped, and many of them regained the weight because their bodies now burned fewer calories at rest.

This is the classic yo-yo dieting trap. Lose weight, lose muscle, metabolism slows, regain fat more easily, end up heavier than before.

What happens with strength training

The resistance training group in similar studies consistently preserved far more muscle mass while losing roughly the same amount of total fat. A 2010 review in the International Journal of Sport Nutrition and Exercise Metabolism found that combining resistance training with a moderate caloric deficit preserved lean mass while maximizing fat loss.

5x5 sends your body an unmistakable signal: you need this muscle. Keep the fat, not the muscle. This is the fundamental reason every fat-loss program should be built around strength training, not cardio.

The calorie burn reality

Let’s be honest about what 5x5 does and doesn’t do for direct calorie burning.

During the session

A 5x5 workout burns approximately 200-400 calories. Compare that to running (400-700 calories per hour) or cycling (300-600 per hour). On a pure calories-per-minute basis, 5x5 loses to cardio.

But that comparison misses the point entirely.

After the session

Resistance training elevates your metabolism for 24-72 hours after training through a process called excess post-exercise oxygen consumption (EPOC). Your body spends energy repairing muscle tissue, replenishing energy stores, and adapting to the training stimulus.

This afterburn effect from weight training is consistently higher than from steady-state cardio. You burn calories while watching television because you squatted that morning.

The metabolic rate advantage

Here’s where 5x5 wins decisively. Every kilogram of muscle you build or maintain burns roughly 13 additional calories per day at rest. That sounds small for one kilogram, but a beginner on 5x5 can add several kilograms of muscle in their first year.

More importantly, muscle tissue you preserve during a diet that would have otherwise been lost keeps your metabolic rate from dropping. A dieter who loses 5 kg of muscle (common without strength training) reduces their daily calorie burn by roughly 65 calories. Over a year, that’s nearly 3 kg of additional fat gained from the metabolic slowdown alone.

5x5 prevents this. Your metabolism stays intact while the fat comes off.

How to set up 5x5 for fat loss

Step one: create a moderate caloric deficit through diet

The deficit drives fat loss. Not the training. Aim for 300-500 calories below your maintenance intake.

Quick calculation: Bodyweight in kg x 33 = approximate maintenance calories. Subtract 300-500 from there.

Don’t go below a 500-calorie deficit. Larger deficits accelerate muscle loss, impair recovery from training, and cause the metabolic adaptation you’re trying to avoid. You should lose roughly 0.5-1% of bodyweight per week. Faster than that and you’re losing muscle.

For a detailed approach to creating and managing your deficit, read the cutting while lifting guide.

Step two: keep protein high

Protein is non-negotiable during fat loss. Aim for 2.0g per kg of bodyweight daily - higher than the standard recommendation for good reason.

High protein during a deficit:

Directly preserves muscle tissue
Increases satiety (you feel fuller)
Has a higher thermic effect (your body burns more calories digesting it)
Supports recovery from training

A 80 kg person cutting should eat at least 160g of protein per day, spread across meals. The complete nutrition guide for 5x5 covers protein sources and meal planning.

Step three: train 5x5 three days per week

Follow the standard program. Squat every session. Alternate between Workout A (squat, bench, row) and Workout B (squat, overhead press, deadlift). Add weight when you complete all prescribed reps.

Expectations during a cut:

Beginners will still add weight to the bar, especially early on
Intermediate lifters should aim to maintain current weights
Progression will slow or stall - that’s expected and acceptable
If recovery suffers after several weeks, drop to 3x5 instead of 5x5

Your goal is to maintain the stimulus on your muscles. The weight on the bar is the signal that tells your body to keep its muscle. Don’t voluntarily reduce it unless you absolutely must.

Step four: optional cardio on rest days

Walking is the most underrated fat-loss tool. Thirty to sixty minutes of walking on rest days burns 150-300 calories, supports recovery, and doesn’t interfere with strength training.

If you prefer more structured cardio, keep it moderate: light cycling, swimming, or the elliptical for 20-30 minutes. Avoid high-intensity interval training on your rest days - it competes for the same recovery resources as your 5x5 sessions.

Cardio is a supplement to your deficit, not the foundation of it. Diet creates the deficit. Strength training preserves muscle. Cardio is a bonus.

Why the scale lies to lifters

This is the section that saves people from quitting prematurely.

The body recomposition effect

A beginner doing 5x5 while eating in a moderate deficit can simultaneously build muscle and lose fat. This is called body recomposition, and it’s the holy grail of training - but it plays havoc with the scale.

Imagine you lose 2 kg of fat and gain 1.5 kg of muscle in a month. The scale shows 0.5 kg lost. You feel like you’re failing. But you’ve actually lost 2 kg of fat while adding lean tissue. Your body composition changed dramatically even though the number barely moved.

What to track instead

Waist measurement: Take it weekly, at the same time of day, at the navel. If this number is going down, you’re losing fat regardless of what the scale says.

Progress photos: Front, side, and back photos every two weeks in the same lighting and clothing. Changes that are invisible in the mirror become obvious in side-by-side photos over a month.

How clothes fit: Your jeans don’t care about body recomposition math. If they’re getting looser, the program is working.

Strength numbers: If your lifts are maintaining or going up while your waist is getting smaller, you’re doing everything right.

The scale is one data point. It’s affected by water retention, glycogen levels, food volume, hormones, and a dozen other variables. Don’t let a single number override all the other evidence that the program is working.

Realistic expectations

Month one

Body recomposition is in full swing. The scale might not move much. You might actually gain a pound or two as your muscles adapt. But your clothes start fitting differently. Your strength goes up noticeably in the gym.

This is the phase where most people quit because they’re watching the wrong number. Don’t be one of them.

Months two and three

Fat loss becomes more visible. The initial water and glycogen fluctuations settle down. If you’ve been consistent with your deficit, the mirror shows clear changes. Strength continues to climb - maybe not as fast as it would with more food, but it climbs.

Months four through six

This is where transformation becomes undeniable. People who knew you notice. The combination of added muscle and lost fat produces a dramatically different physique even if total weight loss is “only” 5-8 kg. Five kilograms of fat loss plus three kilograms of muscle gain looks like a completely different person.

The common mistake: too much cardio, not enough lifting

The default fat-loss approach for most people is: eat very little, do lots of cardio. This is the worst possible strategy for body composition.

Excessive cardio combined with an aggressive deficit sends your body every possible signal to shed muscle. You burn calories during the activity but fail to provide the stimulus that preserves lean tissue. You end up lighter on the scale but with a higher body fat percentage than when you started - the “skinny fat” outcome nobody wants.

Flip the priorities. Lift three days per week on 5x5. Eat in a moderate deficit with high protein. Walk on rest days. That’s it. This produces better body composition results than any amount of jogging on a treadmill.

The bottom line

5x5 doesn’t burn as many calories as running. It doesn’t torch fat in a single session. What it does is far more valuable: it builds and preserves the muscle that makes you look good, keeps your metabolism intact, and ensures that every kilogram you lose comes from the right place.

Combine 5x5 with a moderate caloric deficit and adequate protein, and you have the most effective body recomposition strategy available to beginners. Explore different program approaches to find the right fit. The results take longer to show on the scale, but they look dramatically better in the mirror and last far longer.
