How Many Calories Do You Burn During a Workout vs. After?

One of the most common questions we hear is, “How many calories did I burn from my workout?”

To help answer that question, let’s talk money.

The traditional method for making money is exchanging time for money. 

You finish a project or complete a few days of work, and you’re compensated for those hours or work that you completed. You work 40 hours in a week and you’re paid for that week in the following paycheck. It’s a one-time compensation for the work completed. This is the common model of making money, and the traditional lens through which people think about burning calories.

Another way to make money is receiving residual income. A person works to complete a product or service, then receives ongoing payments or royalties after the work is already done. An example of this is writing a book and receiving continued payments for the book as it continues to sell. 

For many, the most valued benefit of exercise is that it “burns” calories, which can help with weight loss or maintaining weight loss (calories are technically “expended,” but “burned” is the more popular phrase). 

Traditionally, we look at exercise through the “time for money” model. We judge exercise by how many calories we burned during the workout, as if a workout was a one-time payment. Viewing exercise in this way is both right and wrong. 

Exercise is exchanging time for calories burned, but workouts also have residual benefits where you continue to burn calories after the workout. This is especially true for exercise at The Perfect Workout.

Calories Burned During the Workout

Hustling through your session at The Perfect Workout must count for something, right? Yes! 

The effort you put into moving quickly through your exercises makes the training more beneficial in a few ways, including increasing the calories burned during your workout. 

According to data from Harvard Health Publishing, exercise similar to The Perfect Workout burns about 4-8 calories per minute. 

Calories burned per minute are influenced by whether a person truly reaches “muscle success” on each exercise, how quickly a person moves when transitioning between exercises, and by how much the person weighs (heavier people burn more calories when working at the same intensity).

Using the Harvard data, a 20-minute session could expend 80 to 160 calories.

Calories Burned After the Workout

As noted before, The Perfect Workout burns calories not only during the session but with residual calories after the workout as well. 

A study published in the European Journal of Applied Physiology showed that a single workout can increase metabolism up to 72 hours afterwards. The metabolism increase in the study was about 70-90 extra calories burned per day. 

This post-workout benefit doesn’t happen with all types of activity. Most activities, such as walking, riding a bike, and jogging, are limited to the calories burned only during the activity. 

Strength training’s intensity boosts metabolism for a prolonged period due to a few factors: 

  • replenishing stored glucose
  • converting lactic acid into glucose
  • elevated levels of some neurotransmitters and hormones
  • returning core temperature and breathing rate to normal levels

In slow-motion strength training workouts, you burn calories during the session and for days after. Evaluating The Perfect Workout through the traditional lens of only calories burned during the session would underestimate it’s value because you forget about all the calories you burn AFTER the workout. 

Combining the workout and post-workout estimates, a workout could burn anywhere from 200 to 340 calories. When considering that this all comes from a single 15-20-minute session, the calories spent for your work is definitely a return on investment.

Strength Training: Exercise for ALL Ages

Strength Training for All Ages

My friend recently decided to “retire” from playing full-court basketball. Since his 43rd birthday, he’s suffered a few aches, pains, and minor injuries after each day of full-court games with younger friends. He is now going to opt for half-court games with friends, which involves much less running. “Full-court basketball is a young man’s game,” he told me. “I had to stop playing at some point.”

Full-court basketball, all-nighters, dying one’s hair pink…there are some things that we enjoy in our teens and early 20s but aren’t a good fit for adulthood. Strength training…is NOT one of those things.

Strength training is a lifelong exercise choice. It’s safe and effective, regardless of age. The goals people have for strength training generally change with age. However, the probability of reaching those goals doesn’t change. Whether 35 or 95 years old, strength training will improve your health and fitness.

A Workout For All Ages

Whether you're a busy mom looking for something quick and efficient, or a senior in need of a safe way to exercise you age, we have a program for you. While each body is unique, our principles of exercise remain the same – this allows us to serve people of all ages and abilities. Select your age range below to learn more about The Perfect Workout for you.

Before we get to talking results, let’s talk safety. Strength training, especially using The Perfect Workout’s slow-speed method, is extremely cautious. Injuries in exercise and sports are caused by an excess of force on tendons, ligaments, bones, or other tissues in the body. The lack of bouncing, jumping, and rapid movements make strength training an activity with very little force, even when a very challenging weight is used. While the exercises are challenging, they do not put an extreme level of stress on the body. 

If strength training was dangerous, the highest risk population for experiencing injuries would likely be older adults. Therefore, let’s look at the injury rate for older adults who strength train. A research article published in the journal Sports Medicine discussed the results of 22 studies with adults, 75 years old and older. Out of the 880 older adults who strength trained in these studies, only one person had a negative health experience. Just one person! The conclusion: strength training is very safe and highly unlikely to cause injury. 

Safety is important, but we also want results. Strength training leads to many health and fitness benefits. The needs and goals for strength training often differ with age. Let’s discuss what strength training offers people at the various stages in their lives.

Strength Training in Your Twenties and Thirties

Strength training provides a range of benefits for younger adults. Men and women can gain strength and muscle within two months. That muscle also enhances male and female attractiveness, according to studies on physical characteristics that men and women find appealing.

Adult athletes also benefit from strength training. Long distance times, sprint speed, and vertical jump all improve after a few months of training. In addition to performance, athletes also become more resistant to injury.

The same athletic benefits apply to adults in their 40s and 50s. In addition to the aforementioned running benefits, men and women can improve their golf game through strength training. Three months of strength training increases driving distance by seven percent while also reducing the risk of common golf injuries (i.e. lower back pain). 

Reducing or preventing lower back pain, plus enhanced strength and muscle, are benefits for all adults in this age range. Other important benefits are preventing age-related weight gain, improving sleep quality, and reducing the risk of chronic diseases that often occur in this age range. Examples of those diseases include heart disease, many types of cancers, and type 2 diabetes.

Strength Training in Your Sixties and Afterwards

Muscles aren’t a “young man’s game.” Men and women of all ages can gain both strength and muscle. The previously mentioned research article from the journal Sports Medicine showed that just 1-3 days of strength training per week led to big improvements in strength and muscle size for adults who are 75 years old or older. Other benefits frequently experienced by those 60 years or older are stronger bones, improved balance, a lower fall risk, enhanced memory and focus, reduced blood pressure and blood glucose, and increased protection against the development of many chronic diseases.

Strength training offers a wide array of benefits, for fitness and health. While you might eventually retire from all-night parties and playing full-court basketball, there’s no need to retire from strength training. Strength training is safe and healthful exercise for life.
