Many of us overestimate our exercise levels – here's how to calculate how much you really do
Calculating Your Heart Rate: Normal And Maximum
- A healthy resting heart rate is usually in the range of 60 to 100 beats per minute (bpm) for an average adult.a
- The estimated maximum heart rate can be calculated by subtracting your age from the number 220. So if you are 4o years old right now, your maximum heart rate would be 180.
- Once the two figures are calculated, one can derive the bpm that one needs to maintain while exercising at moderate intensity. This can be done by subtracting the resting heart rate from the maximum heart rate, and then adding the desired heart rate reserve to your resting heart rate. This figure is usually above 40 percent of one’s heart rate reserve.

HIIT: high-intensity interval training
HIIT workouts generally combine short bursts of intense heart-pounding exercise (during which a person’s heart rate reaches at least 80 percent of its maximum capacity, usually for 1 to 5 minute...

...has to do with heart health: Intervals can boost cardio-respiratory health with a smaller time investment compared to continuous forms of exercise.
It's not about superior fat-burning capacity or bigger muscles, but about improved VO2 max, a measure of endurance that calculates the maximum volume of oxygen the body can use.
VO2 max is one of the best predictors of overall health.
HIIT and weight loss
People can burn comparable amounts of calories in HIIT routines lasting, compared to longer continuous exercise routines. But this doesn't mean that calorie burn translates into weight loss.
This is the problem with HIIT, just like with any other form of exercise: it’s much easier to lose weight by cutting calories in your diet than trying to burn excess calories.

Decrease in Human Strength
Historic evidence suggests that for many thousands of years, human beings were more active and stronger than today.
The early humans had increased movement and activity, like going for long and tiring hunts, walking long distances that took weeks, making the prehistoric humans fitter than the best athletes today.
Technology as the Culprit
Technological breakthroughs have reduced our activity to a great extent ( vacuum cleaners, washer-dryers, self-cleaning ovens, and even cars).
The rise of the internet gave us a whole lot of technology, curbing our need to move even more.

Incidental physical activities
Are physical activities undertaken as part of carrying out normal daily chores.
Brief sessions of 20 seconds of stair-climbing (60 steps) repeated 3 times a day on 3 days per week over 6 weeks for example can lead to measurable improvements in cardiorespiratory fitness.
Incorporating incidental physical activity into our routines
- Replace short car trips with fast walking, or cycling;
- Walk up the stairs at a fast pace instead of using the elevator;
- Vigorous walk at a pace of about 130-140 steps per minute;
- Look for opportunities to walk uphill;
- Take your dog to an off-leash area and jog for 30-90 seconds alongside the pup.
