Time-Saving Exercise Habits Starting from 1 Minute a Day [Morning Activity Burpee Research Journal] #182

Morning Activity Burpee Research Journal (2026/2/20)

Session Overview

• Set Name: 1-Minute Burpee (Normal Operation - Form Adjustment Training | Chest Strap)

• Reps: 18 reps (First half 9 / Second half 9) / Second half maintenance rate=100% / Initial movement: 3 reps/10s (3.33 s/rep)

• Heart Rate: Start 82 → 30 seconds 114 → End 141 / Average 123 / Max 141 / HRR60=40 / RPE=7.5

• 60-second Average Tempo: 60÷18 = 3.33 s/rep / ΔHR30=+32 bpm (82 → 114)

Sensory Notes

Today, I pushed myself just a little bit.

The last few days have been about re-learning form.
Scapular movement, core stability,
accuracy over speed.

The result was 18 reps.

・Max Heart Rate: 141
・Recovery Heart Rate (60 seconds): 40
・Aerobic Zone (HRR 80% or higher): 0 seconds
・Anaerobic Zone (HRR 90% or higher): 0 seconds

I increased the intensity just a little.
I didn't overdo it.
But I wasn't just playing it safe either.

Within the range where my form doesn't break down,
I shift up one gear.

In the past,
on days I pushed, I would go all out.
On days I played it safe, I would play it completely safe.

But now it's different.

I push carefully.

On top of the foundation built through training,
I add just a little bit of load.

If that doesn't break down,
I add a little more.

Don't rush.
But don't stop.

What is VILPA? Short-duration high-intensity exercise

VILPA (Vigorous Intermittent Lifestyle Physical Activity) refers to short bursts (30–120 seconds) of 'breathless' exercise incorporated into daily movement or chores. Actions such as running up stairs, jogging through a train station, or walking briskly while carrying heavy bags qualify as VILPA. In recent years, research using wearable accelerometers has progressed, and it has been reported that
even extremely short bouts of high intensity can be associated with reduced health risks if accumulated. Note 1

Today's Evaluation (Key Points)

• Pacing ◎ (9→9): 100% maintenance rate. Even with form adjustments, I was able to maintain the 'same rhythm until the end'

• Heart rate rose but did not peak: Max 141, T80=0s, intensity focused on technique + circulation rather than pushing to the limit

Metabolic Load Score

Standard: Karvonen (HRmax=182, HRrest=50, HRR=132)

Simple Metabolic Load (HR-TRIMP60) = 33.18 / 60
[███████████░░░░░░░░░] 55%

Z4 Duration (T80=0s)
[░░░░░░░░░░░░░░░░░░░░] 0%

Z5 Duration (T90=0s)
[░░░░░░░░░░░░░░░░░░░░] 0%

• Z-Load (Weighted Zone Seconds): 0 seconds (= 0 + 2×0 → 0%/60s)

• ΔHR30: +32 bpm (82 → 114)

• Cost/rep (Karvonen): 1.84 (=(( 123−50)/132)×(60/18)) )

Energy Estimation (Roughly)

PCr 4% / Glycolysis 16% / Aerobic 80% ... Z4 not reached, aerobic-dominant. Today is the perfect intensity for a 'tune-up and cycle' day.

Energy estimation: PCr 4% / Glycolysis 16% / Aerobic 80% / Cost/rep (Karvonen): 1.84

Those who lack time should try 1-minute bodyweight exercises

Due to the nature of my work, I travel often, and many people find it difficult to secure a block of time for training.

Even with 'just 1 minute of exercise,' you can create time to feel changes in your body. Burpees require no equipment or space. That is why you can do them in a hotel room. By facing your own body for '1 minute in the morning,' it becomes a habit that

allows you to start your day positively.

I explain the detailed method for burpees in this article.
Even if you are not good at exercise, you will understand how to do burpees that you can continue in a short time.
