Time-Saving Exercise Habits Starting from 1 Minute a Day [Morning Activity Burpee Research Journal] #285

Morning Activity Burpee Research Journal (2026/6/12)

Session Overview

• Set Name: 1-Minute Burpee (Normal Operation | Chest Strap | No PU - Alternating Flutter Kick Squats)

• Reps: 16 reps (First half 8 / Second half 8) / Second half maintenance rate=100% / Initial movement: 3 reps/10s (3.33 s/rep)

• Heart Rate: Start 76 → 30 seconds 127 → End 137 / Average 126, Max 140 / HRR60=47 / RPE=7.5

• 60-second average tempo: 60÷16 = 3.75 s/rep / ΔHR30=+51 bpm (76 → 127)

Sensory Notes

Yesterday was full burpees.
Because I did them thoroughly,
I wanted to start today with a slightly more relaxed approach.

Burpees performed alternately with flutter kick squats to cruise through lightly.

Recently, I felt this form
was easy to use as active recovery.
I can move a little.
But, I don't push too hard.
I thought I could aim for that kind of balance.

I set the timer for 1 minute and started.

While doing it,
I certainly had the feeling of "holding back."
At the very least,
it didn't feel like I was pushing myself to the limit.

The result was 16 reps.

・Max Heart Rate: 140
・Recovery Heart Rate (60 seconds): 47
・Aerobic Zone (HRR 80% or higher): 0 seconds
・Anaerobic Zone (HRR 90% or higher): 0 seconds

I realize it a little while after finishing.

Surprisingly, fatigue remains.

Here I thought again.
That once squat movements are included,
it doesn't become a complete rest for the body.

Of course,
it's not that I was trying to rest today.
I intended to move a little and get myself in order.
That was the plan.
It seems the content of that "little"
was more substantial than I thought.

In the end,
I think a burpee is a burpee.

The form changes.
The areas of stimulation change as well.
But the sense of load from the exercise itself
does not disappear easily.

That is both the interesting part
and the part that should not be underestimated.

Even if I intend it as active recovery,
burpees are still on the high-intensity side.
It was a morning where I felt that once again.

Today's Evaluation

• Distribution ◎ (8→8): No push-ups, no loss of speed with alternating flutter kick squats. Good content for a low-impact adjustment day

• Heart rate is modest: Average 126, Max 140, T80=0s. Today was not a day to chase cardio, but a day that prioritizedprecision in connecting movements and recovery.

• HRR60=47 is good: At RPE 7.5, the recovery is not bad either. A log that makes it easy to connect to the following days without accumulating too much fatigue

Metabolic Load Score

Standard: Karvonen (HRmax=185, HRrest=50, HRR=135)

Simple Metabolic Load (HR-TRIMP60) = 33.78 / 60
[███████████░░░░░░░░░] 56%

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

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

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

• ΔHR30: +51 bpm (76 → 127)

• Cost/rep (Karvonen): 2.11 (= ((126−50)/135)×(60/16)) )

Energy Estimation

PCr 3% / Glycolysis 14% / Aerobic 83% … Z4 not reached, primarily aerobic. Today, with no push-ups, alternating flutter kicks and squats rather than cardiopulmonary stimulation, it is good as a log focused on adjustment and recovery by connecting movements with low impact

Energy estimation: PCr 3% / Glycolysis 14% / Aerobic 83%
Cost/rep (Karvonen): 2.11

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.

For detailed instructions on how to do burpees, please see this article. You will learn how to do burpees that you can continue in a short time, even if you are not good at exercise. »
