Are Strength Training Workouts Good for Weight Loss? – Everyday Health

High-intensity interval training (HIIT) and other types of aerobic exercise get a lot of attention when talking about exercise for weight loss. But strength training whether free weights or bodyweight-only may help budge the number on the scale, too.

Read on to learn how. Then use our four-week plan to get started with strength training for weight loss.

Like other forms of exercise, strength training challenges your body, which increases your calorie burn (compared with just sitting still). Weight loss happens when you burn more calories than you consume over a period of time. So if you pair strength training with a moderate calorie restriction, you may lose weight over time.

Speaking strictly about calories burned, aerobic exercise generally wins over strength training. According to estimates fromHarvard Health, a 155-pound person burns roughly 108 calories in 30 minutes of general weight lifting. That same person burns 252 calories, cycling at a moderate intensity for the same time.

But strength training can bolster healthy weight loss beyond the simple equation of calories burned, explains Mike T. Nelson, PhD, an exercise physiologist in Minneapolis. Only looking at [resistance exercise] in terms of calories in, calories out is a little too reductionist for my taste.

Research suggests that resistance or strength training is part of a weight loss program (along with calorie restriction or aerobic exercise) for overweight or obese adults, those interventions are more effective. Thats because strength training helps promote muscle growth, while reducing overall body fat, more evidence shows.

Typically, weight loss efforts (calorie restriction plus aerobic activity) cause people to lose muscle in addition to fat, Dr. Lyon explains. But when youre resistance training, youre building muscle, so youre preserving that strength while burning extra calories. Aerobic activities (running, jogging, cycling, and others) also strengthen the muscles youre working, but generally less effectively than resistance training does.

The real benefit of strength training for weight loss lies in the maintenance of lean tissue, says Gabrielle Lyon, DO, a functional medicine practitioner and the founder of the Institute for Muscle-Centric Medicine in New York City.

In short: When youre resistance or strength training as part of a weight loss plan, the pounds that you lose are more likely to come from fat mass than muscle mass compared with weight loss plans that include calorie restriction alone or just calorie restriction and aerobic exercise.

Why do you tend to lose more fat mass than muscle mass when strength training is part of a weight loss plan? Theres the fact that youre building muscle. Plus, muscle is metabolically active tissue that requires energy (calorie expenditure) to maintain. In contrast, fat does not, per apast report.

Losing muscle has the undesirable effect of lowering your resting daily calorie burn, which can lead to weight gain over time (unless youre accordingly limiting calorie intake), Lyon explains. In fact, muscle loss is a key reason many people gain fat as they age, according topast research.

Strength training can help you keep your metabolism up and prevent unwanted fat gain, Dr. Nelson notes.

In a systematic review and meta-analysis published in September 2021 in Sports Medicine, researchers gathered data from 58 research papers that used highly accurate forms of body measurements like body scans (these differentiate between fat mass and lean mass). Their findings reveal that people in the studies lost an average of 1.4 percent of their total body fat after five months of only strength training.

Those results are similar to how much you might lose through cardio. The strength training programs differed between studies, but participants trained for roughly 45 to 60 minutes per session, an average of 2.7 times per week.

More importantly, the muscle you build through strength training helps your body use nutrients from food. When you contract skeletal muscles, they secrete myokines, proteins that help with directing and partitioning fuel like carbohydrates (glyocgen and glucose), Lyon says.

Researchshowsthat resistance training improves insulin resistance, which when your cells dont respond to insulin, a hormone your pancreas makes to help regulate blood sugar levels. When your body cant respond to insulin, your body has to make more, causing insulin levels to stay elevated. Elevated insulin levels can result in weight gain and diabetes, per theCleveland Clinic. By extension, improving insulin resistance may help with weight loss and weight maintenance.

For weight loss specifically, Lyon recommends strength training for 45 minutes three or four days per week, and working hard enough where youre close to total muscle fatigue for the muscle group youre working at the end of your sets (or the feeling like you couldnt do one more rep). This doesnt mean you have to lift heavy, but you have to put in enough effort to feel like youre being challenged, she adds.

You can start with fewer or shorter strength sessions, if needed. However, aim to perform at least two full-body strength workouts per week, as outlined in the U.S. Department of Health and Human Services (HHS) physical activity guidelines. Opt for bodyweight, resistance band, free weight, or exercise machine workouts.

Add 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity aerobic exercise (also included in the guidelines) per week for a balanced workout regimen.

Lyon also recommends incorporating high-intensity interval training (HIIT) a few times a week (which can count toward the HHS aerobic exercise recommendations). High-intensity interval training is a very efficient way to move the needle compared with steady-state cardio, which ends up taking a lot of time, she notes. Try alternating a 1-minute sprint on a stationary bike with a 1-minute recovery until you reach 10 minutes.

Before you start training or change your workout routine, get checked by your health care provider if you have a preexisting condition like hypertension, diabetes, osteoporosis, chronic obstructive pulmonary disease, a heart condition, or another issue that may interfere with your ability to safely exercise, says Robert Waskowitz, MD, an orthopedic surgeon and sports medicine specialist with Orthopedic Associates of Hartford in Connecticut. Your doctor can review your workout program and make suggestions in terms of what will be both safe and effective for you, he adds.

Once youre ready to begin, try this program approved by Lyon:
