32 Minutes A Week?!

​

You might wonder how anyone could “keep fit in just 32 minutes a week.” Well, I do it—and you can, too. In fact, it’s even easier than it sounds.

​

The weekly program includes three types of exercise: rebounding, whole-body vibration, and HIIT (High-Intensity Interval Training).

​

​

Rebounding

​

In my home, I keep a rebounder positioned at the edge of my “dining room.” Since I walk between the other rooms and the kitchen several times a day, I use those moments as quick workout opportunities. At least five times a day, I pause for a brief set of ten jumps. Each set takes no more than 12 seconds. So, being generous, that’s about two minutes a day. Multiply that by seven days a week, and you get a total of just 14 minutes.

​

Here are the benefits you can gain from doing this small amount of rebounding:

​

Rebounding in short, frequent bursts—like ten light bounces, five times a day—packs a surprising amount of full-body benefit into a tiny window of time. Each mini-session kick-starts your lymphatic system, which relies on gentle, rhythmic movement to clear cellular waste and strengthen immune function. Those quick acceleration–deceleration cycles also wake up your deep stabilizer muscles, sharpen your balance, and boost circulation without putting any strain on your joints. And because these bursts are scattered throughout your day, they act like little “metabolic reminders,” keeping your body from drifting into long stretches of inactivity.

​

Over the course of a week, these micro-sessions add up to real fitness gains: better cardiovascular tone, more engaged core muscles, improved posture, and a noticeable lift in overall energy. Regular rebounding also supports bone density through mild, consistent loading, enhances mood thanks to endorphin release, and may even aid digestion by gently stimulating abdominal movement. Each session may be tiny, but the routine—steady, daily, repeated movement—creates a surprisingly powerful and easy fitness foundation.

​

​

Whole Body Vibration

​

In my setup, the whole-body vibration machine sits right beneath my stand-up desk. Even as I’m writing this, it’s quietly humming away—gently sending beneficial vibrations through every part of my body. I use it for at least 30 minutes a day while I work, without carving out any extra time for exercise. In practical terms, the amount of time I spend on this activity is zero, because it happens seamlessly alongside whatever I’m doing on my computer.

​

Here are the benefits I experience from this weekly routine:

​

Standing on a whole-body vibration (WBV) machine for an active 30 minutes a day—seven days a week—delivers a surprisingly wide range of fitness and health benefits that steadily build over time. The rapid vibrations trigger your muscles to contract reflexively dozens of times per second, giving you an unexpectedly thorough workout even though you’re standing still. Over the course of a week, this consistent stimulation improves muscle tone, boosts circulation, and enhances lymphatic drainage, helping your body clear metabolic waste and reduce inflammation. WBV also provides gentle, repeated loading to your bones, supporting bone density and long-term skeletal strength without stressing your joints. Many people also notice better balance, coordination, and body awareness because the subtle instability constantly challenges the neuromuscular system.

​

But the benefits extend beyond muscles and bones. Daily vibration can increase flexibility, mobility, and overall range of motion, while the enhanced blood flow helps your tissues recover more quickly. The steady rhythmic motion also activates the parasympathetic nervous system, promoting relaxation and improving mood. And from a metabolic perspective, those daily 30 minutes help nudge energy expenditure upward and improve how your body uses glucose. When you stack these small advantages day after day, the result is a low-impact, time-efficient fitness habit that strengthens your body, builds resilience, and boosts everyday vitality—all without requiring strenuous effort.

​

​

High Intensity Interval Training

​

For HIIT, I follow the recommended structure: three 20-second all-out bursts, with rest in between, done three times on Monday, three times on Wednesday, and three times on Friday. There are many exercises that work well for HIIT, but mine is refreshingly simple. I hold a 3-kg (6.6 lb) ring dumbbell in each hand. With a countdown timer set for 20 seconds—and “Flight of the Bumblebee” blasting for motivation—I pump the weights up and down as fast as I can. For those 20 seconds, I go absolutely full-out; honestly, I couldn’t sustain that pace for much longer.

​

After each burst, I take at least a five-minute break to do something else, and by then I feel fully recovered and ready for the next round. Even counting the setup, each session takes less than two minutes. That adds up to six minutes per day—just 18 minutes a week.

​

Here are the documented benefits of a routine like this:

​

Research comparing moderate-intensity continuous training—think 30 minutes a day, five days a week—with very short bursts of high-intensity interval training (HIIT) shows that both methods can significantly boost cardiovascular fitness and metabolic health. The surprising part is that HIIT often delivers the same benefits in a fraction of the time. Meta-analyses consistently find that HIIT can produce equal or even greater improvements in VO₂ max (a key measure of aerobic fitness), along with similar reductions in body fat and waist circumference, compared to traditional moderate-intensity exercise.

​

In short, instead of spending 150 minutes a week on steady workouts, just a handful of well-executed, high-intensity bursts can offer nearly comparable improvements in major health and fitness markers.

​

Quod Erat Demonstrandum (Q.E.D.)

​

There you have it:

​

• Rebounding: 14 minutes a week

• Whole-Body Vibration: 0 minutes a week (yet yielding 210 minutes of actual WBV exercise)

• HIIT: 18 minutes a week

​

Total: just 32 minutes a week.

​

So tell me—why wouldn’t you start exercising when this is all it takes to reach the level of fitness I enjoy at age 81?

​

And just for fun: I’ve challenged several young men in China—students from my classes, regular gym-goers—to arm-wrestling matches. I managed to beat about 85% of them.
