Time-Saving Exercise Habits Starting from 1 Minute a Day [Morning Activity Burpee Research Journal] #254
“The body remembers repeated movements”
Morning Activity Burpee Research Journal (2026/5/9)
Session Overview
Set Name: 1-Minute Burpees (Standard to Rotation Burpees | Chest Strap | No PU)
Reps: 25 reps (First half 12 / Second half 13) / Second half maintenance rate=108.3% / Initial movement: 4 reps/10s (2.50 s/rep)
Heart Rate: Start 94 -> 30s 137 -> End 161 / Average 143, Max 161 / HRR60=45 / RPE=8.5
60-second average tempo: 60÷25 = 2.40 s/rep / ΔHR30=+43 bpm (94 -> 137)
Sensory Notes
Today I am doing Rotation Burpees. I have sealed off push-ups for the past two days.
Recently, I have been using the front side of my body too much.
I feel like the burden of pushing movements in particular has been accumulating.
For now, I am intentionally resting my arm techniques.
I set the timer to 1 minute and started.
Without the push-ups, the tempo definitely increases.
The number of reps also tends to grow naturally.
But it is by no means an easy burpee.
At first, I was a bit dismissive of it.
Thinking, 'It should be a bit lighter without the push-ups.'
But in reality, it was different.
It doesn't end with just the rotation.
After rotating, I return to the landing point.
Without letting my axis waver, without losing balance, I connect to the next movement.
Each time, my core and lower body are worked harder than I thought.
The result was 25 reps.
・Max Heart Rate: 161
・Aerobic Zone (HRR 80% or higher): 10 seconds
・Anaerobic Zone (HRR 90% or higher): 0 seconds
I beat yesterday's record.
I am genuinely happy that I reached 25 reps.
I feel like I truly understood the 'real difficulty' of rotation burpees today.
Instead of simple back-and-forth repetition, I change direction, return, and carve again.
When busyness piles up, the content feels heavier than it looks.
In exchange for giving my arms a little rest, the core strength and balance take center stage this time.
Burpees really do show a different face just by changing the form slightly.
The variation I started half-jokingly is training me more thoroughly than I expected.
Today's Evaluation
25 reps is quite strong: with rotation and direction changes,25 reps, and a12→13second-half build. Clearly high as a pure rep count standard
Heart rate is 'moderate' relative to rep count: Without push-ups, it's easier to increase the rotation speed, and today the value ofagility, movement switching, and leg rotationis greater than cardiopulmonary effort
Metabolic Load Score

Energy Estimation
PCr 5% / Glycolysis 19% / Aerobic 76% … Z4 is short at 10 seconds, but with rotations and changes in direction, 25 reps is quite a high rotation power. Today, the progress in agility and movement efficiency is greater than in cardiorespiratory fitness.

Those who lack time are the ones who should do 1-minute bodyweight exercises.
Due to the nature of their work, many people travel frequently and 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 even 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.
Detailed instructions on how to do burpees are explained in this article. You will learn how to do burpees in a time-saving way that you can continue even if you are not good at exercise. »
