Doing This One Thing While Strength Training Burns Twice As Many Calories, Science Says

Many people just beginning their fitness journey toward a lean, toned physique make the mistake of focusing solely on cardio and aerobics. Exercises like jogging, walking, and cycling are no doubt a major ingredient while cooking up a leaner look, but failing to add in some weightlifting is like serving a PB&J sandwich without the jelly. It just isn't going to work!

Indeed, if you still mistakenly believe the weight room is only for seasoned athletes or bodybuilders, you're sabotaging your lean body goals right from the start. "You may lose weight faster doing cardio only, but unfortunately it's the wrong kind of weight," Greg Justice, PT, told Women's Health. "Weight training builds lean muscle mass, which elevates your metabolism and burns more fat, even when you're not exercising."

Moreover, this study published in the International Journal of Sport Nutrition and Exercise Metabolism concludes that combining a clean diet with strength training is effective at simultaneously burning unneeded fat while preserving muscle mass. So, it's quite clear that strength training, in general, is helpful for weight loss. That being said, making one relatively minor adjustment to your weightlifting routine can potentially help you burn twice as many calories.

Prioritize more reps over heavy weight

It can be tempting to lift the heaviest weights you can handle, but science tells us that choosing to prioritize rep quantity over heavy weights helps burn significantly more calories.

This study released in the Journal of Strength and Conditioning Research tracked calories burned as a group of young men either performed lots of bench press reps with low weight or performed a much heavier bench press for just a few repetitions. Incredibly, subjects who performed more reps with lighter weights ended up burning close to double the calories as the others.

"What type of lifting 'burns' the most calories, muscular endurance (high reps), or strength-type training (heavy weight)? The answer appears to be muscular endurance-type exercise," the study concludes.

Another study published in Diabetes Care came to similar conclusions, discovering that those who performed just a few reps with heavy weights burned far fewer calories than others who performed more reps with lighter weights.

These findings shouldn't serve as an excuse to take it easy while working out. Your strength training sessions should still be strenuous. Instead of lifting the heaviest weights you can only handle for 1-5 reps at a time, go for lighter barbells in 15-25 rep increments. Your muscles should still be burning and exhausted afterward, but all of the extra energy used performing more reps will translate into extra calories burned.

You'll still build strength

If you're worried that lifting lighter weights will sabotage your big bicep dreams, put your mind at ease. Science tells us that a high-rep approach to weightlifting can build muscle and strength just as well as heavier weights and low reps.

Research published in the Journal of Applied Physiology tracked a group of experienced weightlifters as they either lifted heavy weights at low reps or performed more reps with lighter weights. After 12 weeks had passed the research team assessed both muscle mass and muscle fiber size. Gains were virtually identical between the two experimental cohorts.

The unifying factor here was that all the participants, regardless of reps or weight, lifted to the point of muscle failure. So, again, as long as you put serious effort into your workout and lift until your muscles are exhausted, choosing light weights and high reps will help build strength just as much as any other weightlifting approach. And you'll burn more calories!

"Fatigue is the great equalizer here," says senior study author Stuart Phillips, professor in the Department of Kinesiology at McMaster University. "Lift to the point of exhaustion and it doesn't matter whether the weights are heavy or light."

You'll have a lower risk of injury

Another advantage to a light weight, high rep approach to strength training is reduced risk of injury. It doesn't take much imagination to envision what can go wrong while lifting heavy weights. The stakes are much higher, as a simple slip of the hand or improper form can result in serious injury. Lighter weights are also easier on the joints, and lots of reps can help strengthen connective tissues.

"Working with light weights allows you to perform movements through your full range of motion properly and precisely," Ashley Verma, founder of boutique barre studio Define.London, told INSIDER. "Plus, the risk of injury is much lower… As we age, we can develop joint problems and this can also be exacerbated by the wrong kind of training. Using lighter weights and incorporating longer reps will only empower the body, not hit it abruptly."

Bonus: Compound exercises burn more calories too

Another great way to burn more calories while building muscle is to choose compound exercises over isolation exercises. A compound exercise, such as a lat pulldown or squat, simultaneously works out multiple muscle groups. Meanwhile, isolation exercises like bicep curls only target one muscle individually.

"The higher your metabolism, the more calories you burn," explains 19-time World Champion powerlifter Robert Herbst. "The best is weightlifting exercises that involve compound movements such as squats, lunges, bench press, and deadlifts that work the major muscle groups. These exercises keep the metabolism elevated for 48 to 72 hours afterward as the body repairs muscle that was broken down and builds new muscle."

These 5 Grocery Items Are Cheaper Than Ever Right Now

The grocery industry has been facing major disruptions. The combined effects of the pandemic, climate change, and economic uncertainty over the past couple of years have culminated in a series of supply chain breakdowns. For the consumer, this means supply shortages , shipping delays , and temporary store closures are becoming more commonplace – and all of the added production cost to suppliers is driving up food prices . The U.S. Bureau of Labor Statistics' Consumer Price Index report for January 2022 was released on Feb. 9, and it tells the story of cost trends for every spending category over the past year. Now the numbers are in, and since January 2021, "food at home" spending has increased 7.4%. Consumers should use this number as a benchmark, Phil Lempert, the consumer behavior analyst and founder behind Supermarket Guru , told Eat This, Not That! "Anything that's substantially less [than the 7.4% increase] is a deal," said Lempert. "When you

When Should I Take Creatine?

Creatine is probably the most well-researched supplement on the market today. Numerous studies have found positive adaptations in strength, power and muscle mass thanks to creatine supplementation—especially when it's combined with resistance training. Although the benefits of creatine are well-known to lifters, the best time to take it isn't common knowledge. Which leads us to some important questions:     Does an optimal time for consuming creatine exist?     If it does, should you take it before or after your workout? According to a new study published in the Journal of Exercise and Nutrition, the timing of creatine ingestion does indeed play a role in getting bigger and stronger. Creatine supplementation before resistance training increases muscular strength and lean muscle mass. Interestingly, taking creatine immediately after lifting weights results in greater muscle growth than taking it immediately before. However, in terms of strength gains, no difference betw

Best Smoothie Habits for Weight Loss, According to Dietitians

When it comes to trying to lose weight , most of us are rather poor math students. We mess up the addition and subtraction all the time. We'll try to subtract calories by skipping meals only to become ravenous later on and undercalculate how much food we've eaten to satisfy that gnawing hunger . That's where smoothies can shine as effective weight-loss tools. Research has found that meal replacement shakes, such as protein and fruit/vegetable smoothies, can help people reduce overall daily calorie consumption if used regularly in place of calorie-dense meals and snacks. Getting into the smoothie habit works for weight loss if you follow the right approach. We asked dietitians for the best strategies for getting the most benefit from your smoothie habit .
